Title	Next Generation Multi-Hazard Levee Risk Assessment
Lead	University of California - Los Angeles [UCLA]
Description	In June 2004, a 350-foot levee section gave way west of Stockton, flooding crops and more than a dozen homes, and challenging state officials to protect the state's water supply. What is the risk of that happening again somewhere in the Delta? In light of agricultural fields sinking, the sea level rising, more frequent and severe floods occurring, and earthquakes looming, improvements are estimated to cost $3.8 - $4.3 billion over the next few decades. This study combines 3-D representations with information on the levee’s structure to analyze how different levees respond to floods, sea level rise, and earthquakes. State officials released the last Delta Risk Management Strategy a decade ago. Since then, scientists have collected significant amounts of data and have developed new procedures to compute the risk of failure. This work will produce new Delta-wide data sets important for characterizing the hazards coming from floods and earthquakes. It will also develop the best method to conduct levee hazard assessments. Applying this new method will ensure wise investments and effective threat mitigation Delta-wide.

Title	Recreational Hunting as an Ecosystem Service of Restoration in the Bay-Delta Watershed
Lead	Santa Clara University
Description	Ecological restoration in the Bay-Delta watershed provides increased access to hunting opportunities for recreational hunters in the region in addition to benefitting native flora and fauna. While increased hunting is not always considered an economic benefit, it is a dividend from investments in habitat restoration. This research will quantify in dollars the economic impact of restoring sites and opening them for hunting. The study will survey members of the public at restored sites in the Bay-Delta and Sacramento River regions that have resulted in new and/or improved hunting access. In addition to the economic analysis, the survey will shed light on two other issues: 1) whether there is a tradeoff among recreational usage, carbon storage, and habitat quality for restored sites, and 2) whether current users perceive an unmet need for recreational access in the region. These analyses will be useful in explaining multi-benefit restoration projects to stakeholders and policymakers, and informative to future decision-making.

Title	Surface Water Quality Monitoring
Lead	California State Water Resources Control Board [SWRCB]
Description	Within the ILRP, growers can opt to acquire one of 2 types of permit coverage: Coalition coverage and Individual coverage. If the coalition option is chosen, a grower is allowed to share the cost of compliance, monitoring and reporting with other members of the coalition and reduces/eliminates grower interactions with the Central Valley Water Board (CVWB). The CVWB will then undertake the water quality monitoring. Ambient water and sediment quality monitoring for agricultural discharge will occur using three types of monitoring: Core Monitoring, Assessment Monitoring, and Management Plan Monitoring. Combined, these three levels of monitoring are designed to characterize the discharge from irrigated agriculture as a result of irrigation and storm water runoff.

Title	Drinking Water Well Monitoring
Lead	California State Water Resources Control Board [SWRCB]
Description	On 7 February 2018 the State Water Board revised the Waste Discharge Requirements (Order) for the Eastern San Joaquin River Watershed. The revised Order includes a new drinking water well monitoring requirement. Beginning 1 January 2019, East San Joaquin Water Quality Coalition (ESJWQC) members must monitor drinking water wells on enrolled parcels for nitrates. High levels of nitrates found in drinking water wells impact public health. Excess nitrates (NO3) in soil are often found in rural and agricultural areas. The most common sources of nitrate are fertilizer, livestock waste, and septic systems. Nitrates in soil are highly mobile and can be easily transported to groundwater. The purpose of Drinking Water Well Monitoring is to identify drinking water wells that have nitrate concentrations exceeding the drinking water standard and notify any well users of the potential health risks.

Title	Grasslands Bypass Project Monitoring
Lead	U.S. Bureau of Reclamation [USBR]
Description	The Grassland Bypass Project has been under waste discharge requirements (WDRs) since 1998. Historically, subsurface agricultural drainage water (tile drainage) and surface runoff (irrigation tail water) from the Grassland Watershed was discharged to the San Joaquin River through Salt Slough and/or Mud Slough (north). These two sloughs are tributary to the San Joaquin River and serve as the primary drainage outlets for the Grassland Watershed. With the start of the Grassland Bypass Project in 1996, all tile drainage from a 97,000 acre area known as the Grassland Drainage Area is consolidated and conveyed through San Luis Drain to Mud Slough, eliminating discharges of drainage water from the Grassland Drainage Area into Salt Slough and wetlands. Reducing selenium in wetland channels is the primary goal of the Project, as elevated concentrations of selenium have been documented to be hazardous to wildlife. The Project prevents discharge of subsurface agricultural drainage water into wildlife refuges and wetlands in central California . The drainage water is conveyed instead through a segment of the San Luis Drain to Mud Slough, a tributary of the San Joaquin River. The Project improves water quality in the wildlife refuges and wetlands, sustains the productivity of 97,000 acres of farmland, and fosters cooperation between area farmers and regulatory agencies in drainage management reduction of selenium and salt loading. The Project is operated by the Bureau of Reclamation and the San Luis & Delta-Mendota Water Authority (Authority).

Title	Endangered Species Project
Lead	California Department of Pesticide Regulation [DPR]
Description	In California, DPR has been studying endangered species protection issues with federal funding since 1988. DPR activities include mapping sites occupied by federally listed species, evaluating pesticide exposure risks to inhabited sites, classifying risk and developing protection strategies to minimize risk as needed. There are currently 359 federally listed species in California including federally protected endangered and threatened species, proposed endangered, proposed threatened and Category 1 candidate species (that await only administrative processes to become protected species). Collectively, the federally listed species may occupy about 16 million acres, or about 16 percent of the land area of the state, albeit at very low densities. Of all federally listed species in California, the San Joaquin kit fox has by far the greatest overlap with agricultural areas, accounting for about 10 million acres in 14 counties, mostly in the agriculturally rich southern San Joaquin Valley. Other species that are interspersed with agricultural areas include birds, mammals, reptiles, amphibians, crustaceans and many plants.

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	Levee Inspections
Lead	California Department of Water Resource [DWR]
Description	DWR, under the authority of Water Code Â§ 8360, Â§ 8370, and Â§ 8371, performs a verification inspection of the maintenance of the SRFCP levees performed by the local responsible agencies, and reports to the USACE periodically regarding the status of levee maintenance accomplished under the provisions of Title 33, Code of Federal Regulations (CFR), Section 208.10. While there are no specific water code provisions directing DWR to inspect and report on Maintenance of the San Joaquin River Flood Control System, DWR has performed inspections and provided reports for many years as a matter of practice that is consistent with Title 33, CFR. The inspections thus verify, for both river basins, that local agencies are performing their legal and statutory responsibilities pursuant to Water Code Â§ 12642 and Â§ 12657, and are meeting their legal obligations under assurance agreements with the State to operate and maintain their flood control projects â€œon any stream flowing into or in, the Sacramento Valley or the San Joaquin Valleyâ€. The State inspects and reports only on the status of maintenance practices and on observable levee conditions. The State does not routinely conduct field studies to assess the structural integrity of the levees or their foundations as part of its annual inspection program. Beginning in 2003, the DWR Flood Project Inspection Section (FPIS) and subsequently the Flood Project Integrity and Inspection Branch (FPIIB) has conducted a field survey of the waterward erosion sites and reported them. In addition, the obvious signs of structural weakness such as longitudinal cracks in the crown or slope of the levee, sloughing, or any other noticeable sign of movement within the cross section of the levee are also reported.

Title	Aquatic Invasive Species Program [CDFW]
Lead	California Department of Fish and Wildlife [CDFW]
Description	The mission of the Invasive Species Program is to reduce the negative effects of non-native invasive species on the wildlands and waterways of California. We are involved in efforts to prevent the introduction of these species into the state, detect and respond to introductions when they occur, and prevent the spread of invasive species that have become established. Our projects address problems with introduced animals and plants, both terrestrial and aquatic. More fundamentally, we try to identify and address the ways by which the species are introduced, typically inadvertently, by human activities.

Title	Water Quality in the Nation's Stream and Rivers
Lead	U.S. Geological Survey [USGS]
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	National Wetland Condition Assessment [NWCA]
Lead	U.S. Environmental Protection Agency [USEPA]
Description	The National Wetland Condition Assessment (NWCA) is a statistical survey that begins to address some of the gaps in our understanding of wetland health by providing information on the ecological condition of the nationâ€™s wetlands and stressors most commonly associated with poor condition. The NWCA is designed to answer basic questions about the extent to which our nationâ€™s wetlands support healthy ecological conditions and the prevalence of key stressors at the national and regional scale. It is intended to complement and build upon the achievements of the U.S. Fish and Wildlife Service Wetland Status and Trends Program, which characterizes changes in wetland acreage across the conterminous United States. Paired together, these two efforts provide government agencies, wetland scientists, and the public with comparable, scientifically-defensible information documenting the current status and, ultimately, trends in both wetland quantity (i.e., area) and quality (i.e., ecological condition).

Title	Moderate resolution imaging spectro radiometer MODIS
Lead	National Aeronautics and Space Administration [NASA]
Description	MODIS (or Moderate Resolution Imaging Spectroradiometer) is a key instrument aboard the Terra (originally known as EOS AM-1) and Aqua (originally known as EOS PM-1) satellites. Terra's orbit around the Earth is timed so that it passes from north to south across the equator in the morning, while Aqua passes south to north over the equator in the afternoon. Terra MODIS and Aqua MODIS are viewing the entire Earth's surface every 1 to 2 days, acquiring data in 36 spectral bands, or groups of wavelengths (see MODIS Technical Specifications). These data will improve our understanding of global dynamics and processes occurring on the land, in the oceans, and in the lower atmosphere. MODIS is playing a vital role in the development of validated, global, interactive Earth system models able to predict global change accurately enough to assist policy makers in making sound decisions concerning the protection of our environment.

Title	Sacramento River Water Quality Monitoring
Lead	Woodland-Davis Clean Water Agency
Description	The Woodland-Davis Clean Water Agency (WDCWA)â€”a cooperative partnership between the City of Davis and the City of Woodlandâ€”was formed to implement the Davis-Woodland Water Supply Project (DWWSP) and construct a new surface water treatment plant to treat water from the Sacramento River which, once complete, will largely replace the Citiesâ€™ current groundwater supply. In October 2013, CH2M-Hill was selected as the Design-Build-Operate (DBO) Company for this project. In anticipation of this new surface water treatment facility, the WDCWA began an extensive source water monitoring program in August 2009. The purpose of this monitoring program was to characterize the quality of Sacramento River water at the DWWSP intake, to assist in the selection of an effective treatment process train, and to provide the required raw water data necessary for obtaining a Domestic Water Supply Permit from the State Water Resources Control Boardâ€™s Drinking Water Program (DWP;formerly under the California Department of Public Health (CDPH)). After fulfilling the initial one-year monitoring program agreed to by CDPH, a scaled down sampling program was initiated to better understand seasonal trends in water quality, and to fill the time gap between the initial 2009-2010 monitoring efforts and startup of the new Regional Water Treatment Facility (RWTF).

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.

Description	Agricultural lands are mapped in the state of California each year, beginning in 2014. In 2014, DWR contracted LandIQ to undertake a comprehensive mapping project for the the state of California. Field-scale assessment of agricultural land use and urban/managed wetland boundaries were determined, and these 2014 data are publicly available on the DWR Land User Viewer interactive map. Following this 2014 work, LanIQ was subsequrntly contracted to continue mapping in and around the state of California, focused on mapping agricultural lands only (2014-ongoing). Aerial imagery provided by the United States Department of Agriculture (USDA) National Agriculture Imagery Program (NAIP) was collected throughout the summer of 2014 by the USDA and used for field delineation, classification and QA/QC of the final product. Multiple Landsat 8 images were used for the initial crop classification. Imagery from the Landsat 8 satellite is free and available every 16 days and provided for temporal analysis throughout the growing season. Ground truth data were collected during the 2014 growing season prior to the initiation of this project. These data were used for training and validation of the mapping analysis. Field data from over 15% of all irrigated land in the Central Valley was collected. 25% of the ground truth data were set aside for independent validation. Analysis in areas that lacked ground truth data was performed using imagery and classification approaches established in areas that were informed by training data.

Description	The USGS National Water Use Science Project (NWUSP), a component of the Water Availability and Use Science Program (WAUSP), facilitates the 5-year compilation of water use estimates for the United States as part of the National Water Census (NWC). The NWC, implemented as part of the SECURE (Science and Engineering to Comprehensively Understand and Responsibly Enhance) Water Act (Subtitle F of Public Law 111-11, the Omnibus Public Land Management Act), provides data and tools designed to support water managers in the accurate assessment of water availability at regional and national scales (https://water.usgs.gov/ watercensus/). Water managers across the United States require more complete, timely, and accurate water-availability information to support policy and decision-making, specifically, data associated with water withdrawals and consumptive use. Recognizing the limitations of current water-use data, the SECURE Water Act authorized a program that supports activities related to data collection and methods research and development at the State level. The USGS Water-Use Data and Research program (WUDR) will provide financial assistance through cooperative agreements with State water resource agencies to improve the availability, quality, compatibility, and delivery of water-use data that is collected or estimated by States. The Act requires that these State water use and availability datasets be integrated with appropriate datasets that are developed and/or maintained by the USGS.

Title	Seismic Hazards Program
Lead	California Department of Conservation [DOC]
Description	The Seismic Hazards Program delineates areas prone to ground failure and other earthquake-related hazards including soil liquefaction (the failure of water-saturated soil), earthquake-induced landslides, surface fault rupture, and tsunami inundation. Cities and counties are required to use these maps in their land-use planning and building permit processes so that these hazards are identified and mitigated for development projects prior to the next major earthquake. Additionally, the program reviews and provides comments on geologic and seismic hazards that apply directly to the design and construction of essential and critical facilities around the state. These facilities include schools, hospitals, nuclear power plants, hazardous waste repositories, and others, typically under contract to other state agencies. The program compiles information about past earthquakes, the potential for earthquakes on major faults, and rates of deformation across California to estimate the potential for future earthquakes. The Seismic Hazards Program works closely with the U.S. Geological Survey to produce earthquake shaking maps that are used in development of building codes and in earthquake damage and loss estimates.

Title	California Cooperative Snow Surveys [CCSS] program
Lead	California Department of Water Resource [DWR]
Description	Established in 1929 by the California Legislature, the California Cooperative Snow Surveys (CCSS) program is a partnership of more than 50 state, federal, and private agencies. The cooperating agencies not only share a pool of expert staff but share in funding the program, which collects, analyzes and disseminates snow data from more than 265 snow courses and 130 snow sensors located throughout the Sierra Nevada and Shasta-Trinity mountains. California is the only western state to perform this function on its own. In the other western states, snow surveys are done by the federally funded Natural Resources Conservation Service, which began its program in the mid-1930s. Both programs are similar, and there is a high degree of cooperation between the two entities. DWR is the lead agency in coordinating the CCSS program, which includes: -Maintaining snow surveying and sampling equipment -Training for our partner agencies -Course measurement schedules and data collection -Fiscal and staff resource needs for the various partners within the program. While monitoring doesn't occur in the Delta, snowmelt estimates are used to develop streamflow forecasts for the Sacramento and San Joaquin Rivers that flow through the Delta.

Title	Physical Oceanographic Real-Time System [PORTS]
Lead	National Oceanic and Atmospheric Administration [NOAA]
Description	PORTSAÂ® is an integrated system of sensors concentrated in seaports that provide commercial vessel operators with accurate and reliable real-time information about environmental conditions. PORTAÂ® measures and disseminates observations, predictions and nowcast/forecasts for water levels, currents, bridge air gap, salinity and meteorological parameters (e.g., winds, waves, atmospheric pressure, visibility, air and water temperatures). This data improves navigation safety by reducing groundings and collisions by up to 60% for commercial and recreational vessels and preventing oil spills. It can also increase shipping efficiency by reducing transit delays and allowing mariners to optimize their cargo load. Mariners need these data, tools, and services to make critical navigation decisions, especially as significantly larger vessels transit through U.S. ports because of the Panama Canal expansion.

Title	Mid-Winter Waterfowl Survey [MWS]
Lead	U.S. Fish and Wildlife Service [USFWS]
Description	Some geese and ducks are not adequately monitored during the spring and summer because they nest in areas not well covered by breeding population surveys. Abundance indices for these species are obtained from surveys on wintering areas. Most of these surveys are targeted at specific species or populations. A nationwide effort to survey all waterfowl is conducted annually in January. This, the Mid-winter Waterfowl Survey, provides information on population trends for some species, distribution on the wintering grounds, and habitat use. The Mid-Winter Waterfowl Survey is conducted cooperatively by the states and the U.S. Fish and Wildlife Service.

Description	The Central Valley Joint Venture (CVJV) is a self-directed coalition consisting of 21 State and Federal agencies, private conservation organizations and one corporation. This partnership directs their efforts toward the common goal of providing for the habitat needs of migrating and resident birds in the Central Valley of California. The CVJV was established in 1988 as a regional partnership focused on the conservation of waterfowl and wetlands under the North American Waterfowl Management Plan. It has since broadened its focus to the conservation of habitats for other birds, consistent with major national and international bird conservation plans and the North American Bird Conservation Initiative. The Central Valley Habitat Joint Venture was formally organized in 1988 and was one of the original six priority joint ventures formed under the NAWMP. Renamed the Central Valley Joint Venture in 2004, the Management Board now consists of nineteen public and private members. The CVJV is currently administered through a coordination office within the U.S. Fish and Wildlife Service, and is guided by a Management Board that receives input and recommendations from a variety of working committees.

Title	Harmonizing pesticide risk management of the Bay Delta watershed
Lead	University of California - Santa Barbara [UCSB]
Description	Objective One: Employ high-resolution irrigation data to predict pesticide risks in the Bay Delta Watershed (BDW). This effort will enable more accurate prediction of health hazards given irrigation is a key driver of pesticide transport to surface and ground water. The effects of irrigation methods to pesticide transport vary significantly in their contribution of pesticides to runoff/leachate due to effects on pesticide build-up/wash-off and soil moisture conditions antecedent to precipitation. Objective Two: Provide harmonized species indicators of pesticide toxic burden releases for the Bay Delta which consider diverse resident taxa and human health. California benefits from a plethora of academic researchers, environmental advocacy groups, municipalities, and government groups working to protect the environment. Due to the complexities of this work, efforts often focus on a particular taxa or environmental compartment. This introduces a significant challenge in evaluating the pros and cons of any particular pesticide use. Currently, 79 of the 208 watersheds near the Delta which receive agricultural pesticide applications have increasing pesticide toxic burdens to aquatic taxa. Enabling evaluation of chemical alternatives which reduce toxic burdens across taxa is important to restoring ecosystem health. Objective Three. Quantify the variability of pesticide degradation and the significance to pesticide risk in the BDW. The degree to which pesticides remain in the soils of the BDW increases their probability for accumulation, transport, and nontarget affects. Degradation is highly variable in soils; an investigation of 10 pesticides in 8 soil types under equivalent conditions demonstrated a mean difference of 540% in the minimum and maximum rate of degradation for pesticides evaluated. Yet, researchers and regulators often only employ the median observed rate of degradation which may under predict risks to waterbodies of the BDW.

Title	Developing a Delta Residents Survey: Understanding the Beliefs and Behaviors of Sacramento-San Joaquin Delta Residents on Natural Resource Management Challenges
Lead	California Sea Grant
Description	The Delta Residents Survey (DRS) was a household survey conducted in the Sacramento-San Joaquin Delta in Northern California in 2023 to better understand residents' attitudes on key social and environmental challenges in the region. The data were collected via a survey (available online through Qualtrics or as a print version), with survey invitations sent by mail to a random sample of 82,000 household addresses in the rural “Primary Zone” of the Delta (survey Zone 1), the suburban and urban “Secondary Zone” of the Delta (survey Zone 2) and Delta-adjacent “EJ Communities” in South Sacramento and South Stockton (survey Zone 3). Maps of the survey zones are available in project documentation and the Results Summary Report. The survey was available in English and Spanish. Over 2,300 responses were received, constituting a 2.9 percent response rate. The survey included 43 multiple choice and short response questions, broken up into five sections around key themes: Sense of place and way of life Regional priorities, concerns, and quality of life Environmental and climate change experiences, concerns, and policy preferences Civic engagement and good governance Demographics The research was conducted by a collaborative team of environmental social scientists across multiple research universities (UC San Diego, UC Davis, UC Berkeley, Oregon State University, and Sacramento State University) and was funded by the Delta Stewardship Council's Delta Science Program (a California State Agency). Significant community engagement and partnership efforts were carried out to improve the relevancy of survey questions and interpretation of data. Additional resources, including summary report of results and other research products using the data, are posted on our project website as they become available: https://ktomari.github.io/DeltaResidentsSurvey/. We also have a GitHub repository, where R scripts (and accompanying plain-text descriptions of the functions used that can be translated into other programming languages) are posted, which provide the easiest way for reading in the data and ensuring variable types are set correctly. We highly recommend using or referencing these scripts for the easiest and most accurate use of the data: https://github.com/ktomari/DeltaResidentsSurvey.

Title	FutureTracts: Leveraging Agent-Based Models to Forecast Land Use Changes in California's Central Valley
Lead	University of California - Santa Cruz [UCSC]
Description	The proposed project is driven by the need to understand how land use has changed historically in California's Central Valley due to various drivers including environmental changes and socio-economic developments. Given the region's dependency on agriculture and its vulnerability to climate change—marked by shifts in precipitation patterns and water availability—it's crucial to model these dynamics accurately to forecast future conditions and plan effectively. Using Agent-Based Modeling (ABM) provides a sophisticated means to dissect past interactions between land use and environmental factors at a granular level. This historical understanding is pivotal as it sets the stage for projecting future scenarios. Additionally, the integration of future hydrology data generated from the CalSim3 model and socio-economic scenarios allows for a comprehensive analysis of potential future states. This analysis aims to explore strategic land use modifications that can meet future socio-economic goals under varying water availability scenarios. This research supports several key science actions, making it highly relevant to current policy discussions. It provides actionable insights into large-scale experiments (Science Action 1C), assesses the impact of climate on ecosystems (Science Action 6A), and explores water allocation strategies (Science Action 6E), thereby equipping policymakers and stakeholders with the necessary tools for informed decision-making. These decisions are crucial for maintaining ecological flows and ensuring the longterm viability of both the agricultural sector and the natural ecosystems upon which they depend.
