Title	Habitat, hatcheries, and nonnative predators interact to affect juvenile salmon behavior and survival
Lead	University of California - Santa Cruz [UCSC]
Description	Chinook salmon are an iconic part of California’s environment and heritage, and important both economically and culturally. In the Sacramento River, the winter-run Chinook population is endangered, and there is strong interest in restoring these populations. To do so, resource managers need to better understand the pressures on wild populations. Predation by nonnative predators affects survival of young salmon but may also affect the behavior of salmon. Changes to salmon behavior also have costs but are not currently considered in management. Managers need information on how predators affect juvenile salmon behavior, how they might vary under different conditions, and how they scale up to affect populations.

Title	The Transport and Dispersion of Rafting Vegetation in the Sacramento-San Joaquin Delta
Lead	University of California - Berkeley [UC Berkeley]
Description	The research we are proposing here is focused on developing a thorough, mechanistic understanding of how rafting vegetation, such as hyacinths or egeria, is transported in the Sacramento-San Joaquin Delta. Our approach is to examine in detail the forces that act on rafts of vegetation, and the resulting raft accelerations, to establish a predictive model of raft pathlines. Our model development will be built around a series of field experiments that include measurements of raft movement using GPS-logging drifters integrated into rafts, tidal and wind-forcing using a boat mounted current profiler and an anemometer, and direct estimation of the water-induced shear stress using a point velocity meter incorporated into the actual rafts. These field observations will be used to critically evaluate a numerical model of both channel (tidal) flows and resulting raft movement. Our initial development will include a highly-resolved channel flow model, which will explicitly capture more lateral variability, including low velocity side “pockets”, than is typically resolved with Delta scale hydrodynamic models. Initially, this will allow us to carefully evaluate the quality of our raft tracking calculations. Once the approach is established to be accurate, however, these high-resolution flows will be used to numerically calculate the effective advection and dispersion of rafts in the Delta channel under consideration. This analysis will be focused on parameterizing the effects on raft transport of structures and processes that are unresolved in typical Delta hydrodynamics models. An example of a process that is likely to be important to parameterize is the trapping and retention of rafts along the perimeter of channels due to off-axis wind forcing, and the resulting along-channel dispersion of rafts. In order to examine the effective advection and dispersion of rafts in Delta channels, we propose to pursue this combination of field and numerical studies of raft transport in locations of increasing complexity: first in idealized, straight channels, then in a natural, sinuous channel and a channel junction, and finally throughout the entire Delta. Our research is strongly motivated by the desire to provide a predictive model of dispersion in the Delta for floating objects that respond to both wind and tidal forcing. Immediate applications involve the movement of hyacinth rafts and egeria to evaluate potential management strategies. Important future applications are likely to include consideration of other biological invasions, due to the potential for rafts to provide a transport pathway, and analysis of the movement of accidental or intentional releases of floating material in the Delta.

Title	Quantifying Factors Affecting Migration Routing and Survival of Juvenile Late-Fall Chinook Salmon in the Sacramento-San Joaquin River Delta
Lead	U.S. Geological Survey [USGS]
Description	Juvenile Chinook salmon emigrating from natal tributaries of the Sacramento River must negotiate the Sacramento-San Joaquin River Delta where they disperse among the Delta's complex channel network. Natural processes and water management actions affect the fraction of the population using different migration routes through the Delta and survival within those routes, but quantifying these relationships has proven difficult. Since 2006, acoustic telemetry techniques have been used to quantify both movement among migration routes and survival within routes, providing the first insights into how route-specific survival contributes to population-level survival in the Delta. In this project, we propose to use existing acoustic telemetry data from multiple sources to 1) Quantify factors affecting migration routing of juvenile salmon emigrating from the Sacramento River, 2) Quantify factors affecting survival of juvenile salmon within specific migration routes, and 3) Simulate population-level survival through the Delta under a limited number of historical and operational scenarios. Collating telemetry data from multiple sources over numerous years offers a unique opportunity to identify important relationships that might otherwise be difficult to detect for any particular study in a given year. Quantifying such relationships is critical to informing resource management that seeks to balance use of water resources with recovery of endangered salmon populations.

Title	Impact of Urbanization on Chinook Salmon, Steelhead Trout, and Their Prey: a Case Study of the American River
Lead	University of California - Berkeley [UC Berkeley]
Description	The American River provides spawning/rearing habitat for Chinook salmon and steelhead, yet passes through 30 miles of dense urban development. Urban runoff contains pyrethroid insecticides that cause the river to become toxic to standard testing species with every storm event. This study will go beyond observed toxicity, and address toxicity to chironomids, caddisflies, and mayflies, key diet components of juvenile fish in the river. A bioenergetic model will be used to evaluate effects of food web changes on young salmonids. Our key approach is the use of river-side systems with flowing river water that allow us to replicate realistic pesticide exposures, while controlling other variables. We will determine sensitivity to pyrethroids and fipronil of salmonid prey taxa, and expose them, as well as standard testing species, in the flow-through systems through six storm events. We will maintain experimental streams containing riverine benthic invertebrate communities, and measure response to the pyrethroid pulses. To supplement analyses of the indirect, food web-mediated effects, we will measure endocrine effects through vitellogenin induction in salmon and steelhead. Finally, one treatment includes river water from which organic contaminants have been removed by activated charcoal, to help establish cause of toxicity. The goal is to determine if known toxicity in the American River is a threat to benthic invertebrates and, through the food web, to salmon and steelhead.

Title	Habitat Values of Native SAV [Submerged Aquatic Vegetation] in the Low Salinity Zone of San Francisco Estuary
Lead	San Francisco State University [SFSU]
Description	We will investigate the importance of native submerged aquatic vegetation (SAV) in providing food web support for native fish species in the low salinity zone of the San Francisco Bay-Delta. These SAV beds, composed primarily of Stuckenia pectinata (sago pondweed), are an extensive feature along many of the islands in Suisun Bay and the west Delta, yet almost nothing is known of their seasonal or interannual patterns, their invertebrate communities, or how their physical structure or food resources influence use by native fishes. We hypothesize that the position of these beds in the shallow subtidal zone along the islands increases habitat options adjacent to wetlands and channels for numerous fish species, including species of concern such as delta smelt and chinook salmon. The objectives of this project are to: 1) characterize patterns in habitat structure, community composition, and productivity of SAV beds in four locations in Suisun Bay and the western Delta over a three year period (with comparisons to non-native Egeria densa beds), 2) document the epifaunal invertebrate community composition and abundance in the Stuckenia beds, 3) assess fish use of these beds through seining and acoustic monitoring of hatchery-tagged fish, 4) utilize stable isotope analyses to evaluate food web relationships within and among the beds, and 5) begin preliminary evaluation of the potential to restore native SAV to subsided lands in this region.

Title	Physiological Mechanisms of Environmental tolerance in Delta Smelt [Hypomesus transpacificus]: From Molecules to Adverse Outcomes
Lead	University of California - Davis [UC Davis]
Description	The proposed project directly addresses priority research detailed by the Delta Science Program to protect native fishes that depend on the Bay-Delta system focusing on adaptations to local habitats and physiological tolerances to key environmental stressors;in delta smelt (Hypomesus transpacificus). Temperature and salinity changes associated with anthropogenic climate change are likely to further exacerbate delta smelt population declines. We hypothesize that delta smelt tolerance to forecasted temperature rises and salinity intrusions into the Bay-Delta system can be assessed at a mechanistic level, and that acclimation thresholds can be established by means of genomic responses. This proposal builds upon successful development of a cDNA microarray for delta smelt containing approximately 2000 individual gene fragments, and the subsequent application of biomarkers for assessing the effects of chemical stressors on larval development with links to swimming behavior. We propose to develop a Next Generation oligonucleotide microarray in delta smelt, with ca. 15K genes, in order to assess mechanistic tolerance to changes in gemperature and salinity. Genomic studies will be conducted integrating effects on energetic activity and swimming performance studies, in an interdisciplinary approach that will permit the establishment of links between tolerance mechanisms and adverse outcomes.

Title	Integrating Ecosystems, Flood Control, Agriculture, and Water Supply Benefits: An Application to the Yolo Bypass
Lead	University of California - Davis [UC Davis]
Description	The Yolo Bypass presents an opportunity to develop mechanisms governing the management of flows across floodplains that balance ecosystem services with economic and recreational functions, and to study the untapped potential of such floodplains to play a role in conjunctive surface and groundwater management. Analysis to the necessary high degree of spatial resolution for such management decisions is generally lacking for the Yolo Bypass. This proposal seeks funding for an interdisciplinary study to better understand the economic, hydrologic, and ecological functioning of land and water across the bypass, and to develop tools that use this knowledge in identifying promising strategies for the timing and configuration of spring inundation. Agronomic, economic, and hydraulic models will be used with formal interviews to study the relationship between flooding and six Yolo Bypass functions: (1) Agricultural Economics, (2) Waterfowl management, (3) Native Fish habitat, (4) Flood Control, (5) Groundwater storage, and (6) Recreation. Data from these first efforts will be incorporated into an optimization model that identifies promising inundation alternatives for ecosystem services which minimize costs to landowners and waterfowl managers, and maximize potential conjunctive use benefits. This synthesis answers the Delta Science Program's request for coupled hydrologic and ecosystem models, and for water and ecosystem management decision support system development.

Title	CASCaDE II: Computational Asessments of Scenarios of Change for the Delta Ecosystem
Lead	U.S. Geological Survey [USGS]
Description	This proposal builds upon an existing model-based effort to develop a holistic view of the Bay-Delta-River-Watershed system. CASCaDE I developed a set of linked models to assess Delta ecosystem response to climate change. In CASCaDE II, we propose to refine and extend those modeling capabilities to assess Delta ecosystem response to changes in climate and physical configuration. With a new state-of-the-art hydrodynamic and sediment model at its core, CASCaDE II will link models of climate, hydrology, hydrodynamics, sediment, geomorphology, phytoplankton, bivalves, contaminants, marsh accretion, and fish. Our goals are to apply these linked models to 1) better understand Delta ecosystem function, 2) assess possible futures of the Delta under scenarios of climate and structural change, and 3) provide science-based information to support the DSC in its co-equal goals of water supply and ecosystem protection. The tools developed will provide an objective basis for anticipating and diagnosing Delta ecosystem responses to planned and unplanned changes. Experiments using the linked models are designed to address questions such as: How will climate change, together with new conveyance structures or increased flooded island habitat, alter water flow and drinking water quality? With projected changes in residence time, turbidity, temperature, and salinity, how will primary productivity, invasive bivalves, marsh processes, contaminant dynamics, and fish populations respond?

Title	Quantifying the contribution of tidal flow variations to survival of juvenile Chinook salmon
Lead	U.S. Geological Survey [USGS]
Description	The purpose of this project is to quantify how tides in the Delta influence survival of juvenile salmon. Juvenile salmon survival increases when there is more flow and the river is less tidally influenced. We hypothesize that the increase in survival is because of reduced travel times causing less exposure to predators. This project will test this hypothesis using multiple models including ones that can predict how management actions that modify tidal patterns affect juvenile salmon survival.

Title	CASCaDE: Computational Asessments of Scenarios of Change for the Delta Ecosystem
Lead	U.S. Geological Survey [USGS]
Description	Agencies of the CALFED Bay-Delta Authority (CBDA) face tough decisions as they search for strategies to meet their programmatic goals of stabilizing water supplies in California, providing safe drinking water to a growing population, and sustaining diverse populations of native species and their supporting ecosystem functions. The challenge of finding balanced solutions to these goals is daunting because of the enormous complexity of the San Francisco Bay-Delta system and its tributary rivers and their watersheds. The challenge grows as we consider the additional layer of complexity imposed by the certainty that all the key forces that drive dynamics of this ecosystem (climate, hydrology, water management, land use, sea level) will change significantly in future decades. This proposal describes a model-based approach for developing a long view of the Bay-Delta-River-Watershed system. The long view will be developed through simulations with linked models to project changes under a range of plausible scenarios of global warming, hydrologic responses, land-use change, reconfigurations of within-Delta habitats, and sea level rise. Our goals are to develop and apply a model-based approach of ecological forecasting to project future states of the Delta ecosystem under prescribed scenarios of change, and to communicate the outcomes of those scenarios to resource managers facing the daunting challenge of meeting CBDP goals in a continually changing world.

Title	North Delta Flow Action: Role of Improved Yolo Bypass Flows on Delta Food Web Dynamics
Lead	California Department of Water Resource [DWR]
Description	Description In a collaborative effort between CA Department of Water Resources, US Bureau of Reclamation, CA Department of Fish and Wildlife, United States Geological Survey, San Francisco State University, and UC Davis, this study will investigate the role of augmented summer and fall flows in the Yolo Bypass and North Delta areas on lower trophic food web dynamics and the benefits to listed fish species. Using both continuous and discrete sampling approaches, this study will relate hydrologic patterns to chlorophyll-a, nutrients and primary productivity, plankton densities and composition (phytoplankton and zooplankton), contaminant concentrations, as well as water quality parameters such as electrical conductivity, turbidity, temperature, and dissolved oxygen. In addition, caged hatchery Delta Smelt will be monitored to determine the effects of the managed flow action and increased food web productivity on fish survival, growth, and behavior. Need Due to the food-limited nature of the San Francisco Estuary, it is critical to understand mechanisms that result in successful food web productivity including phytoplankton blooms. Food limitation is one of the primary hypothesized causes of the Pelagic Organism Decline. In 2011 and 2012 there was evidence that a moderate Yolo Bypass flow pulse during fall agricultural drainage periods was followed by phytoplankton blooms in the lower Sacramento River. Managed flow actions in the following years showed an increase in food web productivity could be repeated;however, results varied across years and flow actions indicating more research is warranted to understand correlations between flow and abiotic conditions, and the biological response of the food web. The increases of summer/fall flows in North Delta, has been considered a management strategy as part of complying with USFWS Delta Smelt Biological Opinion Action 4. The augmentation of flows through the Yolo Bypass/North Delta is also included as one of several Delta Smelt Resiliency Strategies by Natural Resources Agency. Objectives • Determine if managed flow actions through the Yolo Bypass stimulate increased primary productivity locally and downstream, and if it is repeatable. • Characterize how nutrients, chlorophyll and plankton (composition and density) in the Toe Drain, Cache Slough Complex, and lower Sacramento River change in response to flow pulses. • Determine if nutrient subsidies of the source water and downstream are limited by abiotic and biotic factors. • Characterize spatial differences and transport of pesticide contaminants in the Yolo Bypass in response to the flow actions. • Determine survival, growth and behavior of caged hatchery Delta Smelt before and after the flow action in the Yolo Bypass.

Title	Effect of Outflow Alteration upon Delta Smelt Habitat, Condition and Survival
Lead	U.S. Bureau of Reclamation [USBR]
Description	Description The Directed Outflow Project (DOP) is a continuing collaborative effort among a dozen state, federal and non-governmental groups. The DOP will employ a focused spatial and temporal approach to evaluate mechanistic hypotheses directly related to the rationales provided for the summer Delta outflow action and Yolo Bypass Toe Drain action to benefit Delta Smelt, with direct relevance to the fall outflow action. Paired data collections (same location and time) of abiotic and biotic habitat constituents to test specific hypotheses will assist in avoiding prior shortcomings of using data collected for different studies/hypotheses and/or across variable spatial/temporal scales (as discussed in MAST [2015] and elsewhere). Sampling will occur during the Delta Smelt juvenile rearing-stage, a period known to be associated with the location of the low salinity zone (LSZ). Results should strengthen our understanding of the mechanisms and drivers impacting Delta Smelt vital rates and associated habitat features with a focus on outflow conditions. Results should assist in evaluating the benefit and feasibility of future flow augmentation actions for managers and decision makers. Results from this and other related studies will inform evaluations on which particular outflow-related action or group of actions provides the most benefit for Delta Smelt. Need Requests and plans for water management actions related to augmentation of Delta outflow have proceeded and are expected to proceed in the future. However, there is uncertainty and disagreement regarding the mechanistic relationship of Delta outflow during the rearing period to Delta Smelt vital rates and habitat, and the hypothesized benefit of outflow alteration for Delta Smelt. Delta outflow has experienced reductions in recent years, coinciding with the collapse of the Delta Smelt. Reduced outflow has been linked to reductions in habitat suitability in Suisun Bay and Marsh and movement of the LSZ to the Confluence of the Sacramento-San Joaquin River where little connection to shallow open water habitats exists. Objectives The DOP’s main objective will be to evaluate the hypothesized benefit of outflow alteration for Delta Smelt and its habitat in coordination with all stakeholder groups. The following process and product related sub-objectives will facilitate progression toward this evaluation objective. • Test mechanistic hypotheses addressing the rationale behind outflow-based actions to benefit Delta Smelt. • Concurrently sample fish and measure abiotic/biotic habitat conditions at each randomly selected location along the salinity and habitat gradient of the north to western Delta along the Sacramento River during the summer and fall.

Title	Pesticide Use Reporting
Lead	California Department of Pesticide Regulation [DPR]
Description	California's pesticide use reporting program is recognized as the most comprehensive in the world. In 1990, California became the first state to require full reporting of agricultural pesticide use in response to demands for more realistic and comprehensive pesticide use data. Under the program, all agricultural pesticide use must be reported monthly to county agricultural commissioners, who in turn, report the data to DPR. California has a broad legal definition of "agricultural use" so the reporting requirements include pesticide applications to parks, golf courses, cemeteries, rangeland, pastures, and along roadside and railroad rights-of-way. In addition, all postharvest pesticide treatments of agricultural commodities must be reported along with all pesticide treatments in poultry and fish production as well as some livestock applications. The primary exceptions to the reporting requirements are home-and-garden use and most industrial and institutional uses.

Title	San Francisco Bay Bathymetry
Lead	U.S. Geological Survey [USGS]
Description	USGS has conducted bathymetric analyses in San Francisco Bay, Suisun Bay, and the Delta intermittently since 1867 based on bathymetry data primarily collected by NOAA"s National Ocean Service (NOS) (formerly the United States Coast and Geodetic Survey (USCGS)). Since the days of hydraulic gold mining, sedimentation in San Francisco Bay has changed drastically. From the 1850's until at least the late 1800's, debris from hydraulic mining in the Sierra Nevada filled the Bay. As hydraulic mining practices ceased, the amount of sediment deposited decreased. In the latter half of the 20th century an increase in the implementation of flood control and water distribution projects in the Central Valley caused the Bay to be erosional due to the reduction of the frequency and duration of peak flow conditions, which in turn decreased sediment supply to the Bay. They have used this information to locate deposits of sediment-associated contaminants, restore wetland areas, and to provide the observable linkage between anthropogenic modifications of the landscapeâ€”such as evolving land use practices, flood control, and water diversionsâ€”and natural forces of climate-driven river flow, sea level change, tides, and wind. In 1999, USGS assessed how sedimentation in the Suisun Bay has changed between 1867 and 1990 (see info sources). They have also worked collaboratively with DWR, using their more recent bathymetry data to produce a high-resolution DEM of the Delta region (see info sources). It is not clear whether USGS will continue their bathymetry surveys. The latest survey is from 2005, and took place in the South of San Francisco Bay (outside the Delta study area).

Title	Mokelumne River Fish Hatchery
Lead	East Bay Municipal Utilities District
Description	The Mokelumne River supports Central Valley fall-run Chinook salmon (Oncorhynchus tshawytscha) (fall-run), which is the only salmon run known to naturally occur in this waterway (Clark 1929). Fall-run are listed as a Species of Concern under the federal Endangered Species Act (NMFS 2004). Camanche Dam, which impounds Camanche Reservoir is the upper limit of anadromous fish migration in the Mokelumne River. East Bay Municipal Utility District (EBMUD) initiated construction of Camanche Reservoir in 1963. As mitigation for blocking access to spawning grounds for salmonids, EBMUD provided funding for the original construction of the MOK in 1964.The MOK is located on the south bank of the Mokelumne River at the base of Camanche Dam. While EBMUD provides funding for fall-run production, the California Department of Fish and Wildlife (CDFW) administers and operates the hatchery. The Commercial Salmon Stamp Fund provided funding for an additional MOK building built in 2002 and continues to financially support the MOK. On an annual basis the MOK produces fall-run for mitigation (Mitigation Element) and for ocean salmon enhancement (Ocean Enhancement Element). The annual MOK production goal is 6,400,000 fall-run smolts (3,400,000 for Mitigation Element and 3,000,000 for Ocean Enhancement Element). The hatchery operations are involved with tagging and monitoring fish to assess the success of the hatchery program.

Description	In 1991, Congress established the National Water-Quality Assessment (NAWQA) Project to address where, when, why, and how the Nation's water quality has changed, or is likely to change in the future, in response to human activities and natural factors. A prominent feature of NAWQA is the development of long-term consistent and comparable information on streams, rivers, ground water, and aquatic systems. The NAWQA Project is designed to answer these questions: 1. What is the current condition of our Nation's streams, rivers, and groundwater? 2. How are these conditions changing over time? 3. How do natural features and human activities affect these conditions, and where are those effects most pronounced? Under the National Water-Quality Assessment (NAWQA) project, there are several surface water and ecology studies, including the Regional Stream Quality Assessment (RQSA) (a baseline assessment of streams), and current conditions and long-term trends monitoring.

Title	Bioassessment Program
Lead	California Department of Fish and Wildlife [CDFW]
Description	Biological assessment (bioassessment) is an evaluation of the condition of a waterbody based on the organisms living within it. It involves surveying the types and numbers of organisms present in the water and comparing the results to established benchmarks of biological health. Scientists and managers around the world use this approach to directly and quantitatively measure the ecological health of a waterbody and to monitor the cumulative impacts of environmental stressors on surface waters. Benthic macroinvertebrates (BMIs) and benthic algae are the primary biota used for bioassessments in California. BMIs are a diverse group of small but visible animals that live at the bottom of rivers and streams. They are comprised mostly of aquatic insects but also include crustaceans, mollusks, and worms. BMI assemblages are found in most waterbodies and are reliable indicators of biological health because they are relatively stationary and respond predictably to a variety of environmental stressors. Benthic algae are also sensitive to environmental stressors and provide environmental condition information that is often complementary to that derived from BMI assemblages. Because of their short lifespans and rapid reproduction rate, algae can respond quickly to changing water conditions. They are also more directly responsive to nutrients (such as nitrogen and phosphorus) and are therefore suited for monitoring nutrient runoff, one of the major environmental stressors in California. SWAMP began conducting bioassessment in 2000. The program continues to work closely with the California Department of Fish and Wildlife's (CDFW) Aquatic Bioassessment Laboratory, which has been the primary producer of this technical work.

Title	Central Valley Chinook Adult Escapement Monitoring Project
Lead	California Department of Fish and Wildlife [CDFW]
Description	The Central Valley Chinook Salmon In-river Escapement Monitoring Plan is a science-based collaborative approach to improve monitoring of adult Chinook salmon returning from the ocean to spawn in CV streams (escapement) and harvested in freshwater. Accurate estimates of escapement are critical to sound management of ocean and inland harvest and monitoring the recovery of listed stocks. A result of requests from fisheries resource managers, the development of this plan was funded in 2007 by the CALFED Ecosystem Restoration Program. The comprehensive monitoring plan includes a spatially and temporally balanced sampling protocol that when implemented will allow for statistically defensible estimates of population status. The plan incorporates an adaptive management strategy, and recommends a standardized database structure, as well as standardized reporting techniques.

Title	Soil Survey Geographic Database [SSURGO]
Lead	U.S. Department of Agriculture [USDA]
Description	The SSURGO database contains information about soil as collected by the National Cooperative Soil Survey over the course of a century. The information can be displayed in tables or as maps and is available for most areas in the United States and the Territories, Commonwealths, and Island Nations served by the USDA-NRCS. The information was gathered by walking over the land and observing the soil. Many soil samples were analyzed in laboratories. The maps outline areas called map units. The map units describe soils and other components that have unique properties, interpretations, and productivity. The information was collected at scales ranging from 1:12,000 to 1:63,360. More details were gathered at a scale of 1:12,000 than at a scale of 1:63,360. The mapping is intended for natural resource planning and management by landowners, townships, and counties. Some knowledge of soils data and map scale is necessary to avoid misunderstandings. The maps are linked in the database to information about the component soils and their properties for each map unit. Each map unit may contain one to three major components and some minor components. The map units are typically named for the major components. Examples of information available from the database include available water capacity, soil reaction, electrical conductivity, and frequency of flooding;yields for cropland, woodland, rangeland, and pastureland;and limitations affecting recreational development, building site development, and other engineering uses. SSURGO datasets consist of map data, tabular data, and information about how the maps and tables were created. The extent of a SSURGO dataset is a soil survey area, which may consist of a single county, multiple counties, or parts of multiple counties. SSURGO map data can be viewed in the Web Soil Survey or downloaded in ESRIÂ® Shapefile format. The coordinate systems are Geographic. Attribute data can be downloaded in text format that can be imported into a MicrosoftÂ® AccessÂ® database.

Description	The Groundwater Ambient Monitoring and Assessment (GAMA) Program is California's comprehensive groundwater quality monitoring program that was created by the State Water Resources Control Board (State Water Board) in 2000. It was later expanded by Assembly Bill 599 - the Groundwater Quality Monitoring Act of 2001. AB 599 required the State Water Board, in coordination with an Interagency Task Force (ITF) and Public Advisory Committee (PAC) to integrate existing monitoring programs and design new program elements as necessary, resulting in a publicly accepted plan to monitor and assess groundwater quality in basins that account for 95% of the state's groundwater use. The GAMA Program is based on interagency collaboration with the State and Regional Water Boards, Department of Water Resources, Department of Pesticide Regulations, U.S. Geological Survey, and Lawrence Livermore National Laboratory, and cooperation with local water agencies and well owners.

Title	Anadromous Fish Abundance and Trends
Lead	Pacific States Marine Fisheries Commission [PSMFC]
Description	In 1998, the Pacific States Marine Fisheries Commission, the California Department of Fish and Game, and the National Marine Fisheries Service began a cooperative effort to collect, archive, and enter into standardized database formats the information generated by fisheries resources agencies throughout California. Data for this project have been collected from a variety of government sources, such as the Department of Fish and Game and the US Forest Service, and non-government sources, such as tribal fisheries monitoring, university research, local watershed stewardship programs, and numerous additional fisheries stakeholders. The database contains a significant amount of information regarding the current and historic status of California's anadromous fish. The building and expansion of the cooperative anadromous fisheries abundance dataset is largely dependent on funding, support, and sharing the vision that this type of program in California is imperative. The wealth of this type of information that has already been compiled into the CalFish database demonstrates what can be accomplished through interagency cooperation.

Title	Freshwater CyanoHABs Program [Blue-Green Algae Harmful Algal Blooms]
Lead	California State Water Resources Control Board [SWRCB]
Description	Observations of harmful algal blooms (HABs) and algal toxins have increased globally in recent years. HABs are problematic because they can affect multiple beneficial uses including recreation, aquatic life, and drinking water by reducing aesthetics, lowering dissolved oxygen concentration, causing taste and odor problems, and producing potent toxins. Water Board staff are working with state and local entities to identify and respond to HAB incidents throughout California. The Water Board first began to formally address this issue in 2005 when it formed the Blue Green Algae Work Group, later renamed the California Cyanobacteria Harmful Algal Bloom Network (CCHAB). An initial product of this group was the Voluntary Guidance Document (original release 2010, updated 2016). Subsequently, SWAMP prepared California Freshwater HAB Assessment and Support Strategy to articulate a coordinated program to assess, communicate and manage HABs in California.

Title	Smelt Larva Survey
Lead	California State Water Resources Control Board [SWRCB]
Description	The Smelt Larva Survey provides near real-time distribution data for longfin smelt larvae in the Delta, Suisun Bay and Suisun Marsh. Sampling takes place within the first two weeks in January and repeats every other week through the second week in March. Each 4-day survey consists of a single 10-minute oblique tow conducted at each of the 35 survey locations (see map) using an egg and larva net. The 505-micron mesh net is hung on a rigid frame shaped like an inverted-U, which in turn is attached to skis to prevent it from digging into the bottom when deployed. The net mouth area measures 0.37 m2. The conical net tapers back from the frame 3.35 m to a 1-liter cod-end jar, which collects and concentrates the sample. Immediately after each tow, juvenile fishes are removed, identified, measured and returned to the water immediately, and the remaining larvae are preserved in 10% formalin for later identification in the Lab in Stockton.

Title	Spring Kodiak Trawl Survey
Lead	California Department of Fish and Wildlife [CDFW]
Description	The Spring Kodiak Trawl Survey (SKT) has sampled annually since its inception in 2002. The SKT determines the relative abundance and distribution of spawning delta smelt (Hypomesus transpacificus). The SKT samples 40 stations each month from January to May. These 40 stations range from San Pablo Bay upstream to Stockton on the San Joaquin River, Walnut Grove on the Sacramento River, and the Sacramento Deep Water Ship Channel. Each 'Delta-wide' survey takes approximately 4 - 5 days per month to complete. Historically, 'Delta-wide' surveys were followed by a 'Supplemental' survey two weeks later to intensively sample areas of highest delta smelt concentration to estimate the proportion of male and female delta smelt that were in pre-spawning, spawning and spent maturation stages. Beginning in 2008, in an effort to minimize take of spawning adults, routine 'Supplemental' surveys were discontinued and are now only conducted under the recommendation of the Smelt Working Group and the approval of managers.

Description	Staff of the Striped Bass Study calculate adult Striped Bass abundance, relative abundance, harvest rate, and survival rate by using data from Commercial Passenger Fishing Vessels (Party Boats;CPFV), various creel surveys, and a mark-recapture program. We monitor the relative abundance of adult Striped Bass by calculating catch per unit effort (CPUE) from data submitted by Commercial Passenger Fishing Vessels. The Department's Marine Region compiles the data, we request the data at intervals, and we calculate CPUE. By applying tags to adult Striped Bass and monitoring the subsequent ratio of tagged fish to untagged fish, we calculate adult Striped Bass abundance, relative abundance, harvest rate, and survival rate. During April and May we use large traps near Knights Landing and nets near Antioch to collect adult Striped Bass, then we tag and release them on-site. Each tag includes our mailing address and a unique code, and some tags include a reward value. By posting "Tagged-fish Wanted" posters around the Estuary and making presentations, we encourage anglers to return tags to us. We also recover tags by talking with anglers during various creel surveys.

Title	Summer Townet Survey
Lead	California Department of Fish and Wildlife [CDFW]
Description	The Summer Townet (STN) Survey was initiated in 1959 to determine relative distribution and abundance of young of the year (age-0) striped bass (Morone saxatilis) in the Delta. To predict fishery recruitment, the survey calculates an index to measure age-0 striped bass year class strength. This index is based on abundance when age-0 striped bass attain a mean length of 38.1 mm. In contrast, the delta smelt (Hypomesus transpacificus) index is the average of the first two survey indices. The delta smelt index was developed about 1990 in response to declining delta smelt abundance. It has proven valuable in gauging the health of the estuary;delta smelt abundance trend data was used as supporting evidence for their listing as threatened in 1992 under the Federal and State Endangered Species Acts. It appears that zooplankton data are also collected.

Description	The California breeding population survey is modeled after the continental breeding survey. Though most of the wintering waterfowl in California breed outside of the state, California still has a significant number that both breed and winter here. CDFW and California Waterfowl Association (CWA) biologists conduct the California survey. Surveyed areas include wetland and agricultural areas in northeastern California, throughout the Central Valley, the Suisun Marsh, and some coastal valleys. CDFW biologists and warden-pilots use a fixed-wing aircraft to fly all of the transects while CWA completes the "ground" portion of the survey using a helicopter. This survey also utilizes a visibility correction factor. For the most part, ducks that only winter in California comprise most of the harvest, but CDFW augments the continental survey assessment with the estimates of California's breeding population for developing hunting regulation recommendations.

Lead	U.S. Geological Survey [USGS]
Description	Our group at the USGS continuously monitors suspended-sediment concentration (SSC), turbidity, dissolved oxygen, temperature, salinity, and water level at many sites throughout the San Francisco Bay (Bay) and the Sacramento-San Joaquin Rivers Delta (Delta). Our work began in 1988 to explore the spatial and temporal variability of water quality and sediment transport and to provide decision makers, resource managers, and the public with the most up-to-date knowledge. Topics we study include water quality, sediment transport, water clarity, erosion and deposition, sediment-associated contaminants and habitat quality, wetland restoration, and sea level rise.
Science topics	Water operations / exports, Water storage, Water conveyance / infrastructure, Surface water / flow, Stage, Velocity, Suspended sediment, Bedload, Deposition, Erosion, Chemistry, Toxicity, Salinity, Water temperature, Dissolved oxygen, Turbidity, Other discharge contaminants, Intertidal / transition zones, Main channels, Sloughs, Open water, Riparian wildlife, Conductivity, Water use / demand, Water intakes, fish screens & passage

Title	Western Regional Climate Center [WRCC] - Weather Monitoring
Lead	National Oceanic and Atmospheric Administration [NOAA]
Description	THE WESTERN REGIONAL CLIMATE CENTER (WRCC) is one of six National Oceanic and Atmospheric Administration (NOAA) Regional Climate Centers across the nation. The WRCC has been housed within DRI's Division of Atmospheric Science since its inauguration in 1986. WRCC acts as a repository for high-quality historical climate data and information for the western U.S., a region covering the eleven westernmost states, including Alaska, Hawaii, and the U.S. Affiliated Pacific Islands. WRCC offers value-added tools and maintains climate services staff to support the analysis and interpretation of climate data in support of decision-making. WRCC also helps to coordinate climate-related activities at local, state, regional, and national scales. Federal partners such as the National Integrated Drought Information System, the National Centers for Environmental Information, the Southwest Climate Adaptation Science Center, and the California Nevada Applications Program support some of WRCC's major activities. In addition to climate services, WRCC staff engage in applied research on a variety of weather and climate topics.
Science topics	Air temperature, Precipitation, Wind, Solar irradiance, Extreme heat, Extreme storms, Non-forested vegetation, Evaporation / evapotranspiration
