Title	Operation Baseline Project 2B: Phytoplankton, CSU Maritime Academy
Lead	California State University Maritime Academy
Description	Planned upgrades to the Sacramento Regional wastewater treatment plant (Regional San) between 2019 and 2021 will reduce total nitrogen inputs by >60% and shift the dominant form of nitrogen entering the Delta from ammonium (NH4) to nitrate (NO3). These changes will affect the Delta in ways unforeseeable with existing knowledge. The focus of this project is to quantify the links between wastewater nitrogen and phytoplankton standing stock, community composition and carbon and nitrogen production. Working in collaboration with the other two Operation Baseline projects, we will: 1. validate in situ monitoring approaches for phytoplankton standing stock and community composition (i.e. using size-fractionated chlorophyll-a and diagnostic phytopigments via HPLC) and 2. provide estimates of ambient and nitrogen-saturated phytoplankton NH4 and NO3 uptake rates as well as C uptake. Phytoplankton N and C uptake rates will be made along spatial gradients in nitrogen and water residence time (Task 1) and in three wetland habitats with varying influence from wastewater nitrogen (Task 3). Together with the other proposals, this project will provide much needed baseline characterization of nutrient processes in the Delta prior to Regional San upgrades.

Title	Operation Baseline Project 2C: Zooplankton, Romberg Tiburon Center, SFSU
Lead	San Francisco State University [SFSU]
Description	This project will examine responses of zooplankton (copepods) to variations in the foodweb attributable to nutrient sources. At each wetland site we will determine spatial abundance patterns and rates of reproduction, growth, and mortality. These will be integrated with information on phytoplankton and physical dynamics to determine how population dynamics responds to nutrient conditions. Stable isotopes will be used to assess nutrient source contributions to growth.

Title	Do light, nutrient, and salinity interactions drive the “bad Suisun” phenomenon? A physiological assessment of biological hotspots in the San Francisco Bay-Delta
Lead	University of California - Santa Cruz [UCSC]
Description	This project assessed the physiological basis for reduced phytoplankton growth in Suisun Bay, prior to the major upgrade at the Sacramento Regional Wastewater Treatment Plant (SRWTP), which is responsible for 90% of the nitrogen released into the bay. The work involved analyzing almost three decades of historical eld data from the bay-delta and using it to build a model to evaluate environmental drivers of phytoplankton biomass. Discoveries from the eld data were then tested through laboratory culturing experiments. By illuminating the interacting e ects of bottom- up drivers (light, nutrients, salinity) on phytoplankton, this research helps provide a fundamental understanding of this complex ecosystem.

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	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	A Multi-Stock Population Dynamics Framework for the Recovery of Sacramento River Chinook Salmon
Lead	University of Washington [UW]
Description	The purpose of this project is to construct a multi-stock salmon population model and management strategy evaluation (MSE) tool that addresses the cross-linkages between water use and fishery ecosystem response. Recent federal court judgment concluded that insufficient evidence was provided for prescribing specific flow restrictions in two recent conservation measures. The inability to provide adequate evidence was a byproduct of not having the correct quantitative tools at hand. We propose to build these tools by furthering technological developments of previous analyses of Central Valley Chinook population dynamics. Specifically, our work will integrate multiple salmon populations together into a single model that can reconstruct historical population dynamics such that environmental conditions and water resource use can be used as predictors of biological responses of multiple populations. Our goal is to integrate populations into a single model so that the effect of water management and fishery management policies can be examined in light of all fish populations simultaneously. This pertains to the biological interactions between the populations as well as the way in which fisheries impact individual populations depending on growth and maturation rate of each population. All analysis will be framed in the context of historical and proposed water use patterns.

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	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.

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	Periodic Groundwater Level Measurements
Lead	California Department of Water Resource [DWR]
Description	Since 2009, the California Statewide Groundwater Elevation Monitoring (CASGEM) Program has tracked seasonal and long-term groundwater elevation trends in groundwater basins statewide. The program's mission is to establish a permanent, locally-managed program of regular and systematic monitoring in all of California's alluvial groundwater basins. This early attempt to monitor groundwater continues to exist as a tool to help achieve the goals set out under the Sustainable Groundwater Management Act (SGMA). Senate Bill x7-6, passed by the legislature in 2009, established collaboration between local monitoring parties and DWR to collect statewide groundwater elevations, to be made available to the public. In response to the law, we developed the CASGEM program. Collecting and evaluating these groundwater data on a statewide scale is a fundamental step toward improving management of California's groundwater resources. The CASGEM program relies and builds upon the many previously established local long-term groundwater monitoring and management programs. Our role is to coordinate the CASGEM program, to work cooperatively with local entities, and to maintain the collected elevation data in a readily and widely available public database.

Forecasts of landfalling ARs are critical to precipitation prediction and yet are in error by +/- 400 km at even just 3-day lead time (see figure to the right;Wick et al. 2013). The concept for AR Recon was first recommended in a report to the Western States Water Council (Ralph et al. 2014) that was prepared by a broad cross-disciplinary group in 2013. AR Recon was conducted with 3 missions in 2016, 6 in 2018, and 6 in 2019. USACE and the California Department of Water Resources were key sponsors of the AR Recon 2018 and 2019 campaigns. Aircraft that are normally used for hurricane reconnaissance were deployed over the northeast Pacific to collect observations to support improved AR forecasts. The data were assimilated by global modeling centers in real-time.

Title	Advanced Hydrologic Prediction Service - Precipitation Monitoring
Lead	National Oceanic and Atmospheric Administration [NOAA]
Description	"Observed" data is a byproduct of National Weather Service (NWS) operations at the 12 CONUS River Forecast Centers (RFCs), and is displayed as a gridded field with a spatial resolution of roughly 4x4 km. "Normal" precipitation is derived from PRISM climate data, created at Oregon State University. The PRISM gridded climate maps are considered the most detailed, highest-quality spatial climate datasets currently available. The 30 year PRISM normal from 1981-2010 is used for precipitation analysis since 2004. Prior to 2004 the 30 year PRISM normal from 1961-1990 is used.

Title	Streamflow Monitoring
Lead	U.S. Geological Survey [USGS]
Description	The USGS works in partnership with more than 1,400 Federal, regional, State, Tribal, and local agencies or organizations to maintain and manage a multipurpose network of streamgages that monitor streamflow and (or) water level. Approximately 8,200 of the more than 10,000 USGS streamgages in the network continuously monitor streamflow year-round and are collectively referred to as the National 'Streamflow' Network (NSN). Approximately 40% of the NSN is made up of Federal Priority Streamgages (FPS), which are considered critical for long-term tracking and modeling/forecasting to ensure that Federal water priorities and responsibilities can be met. Such priorities and responsibilities include forecasting hydrologic events (floods and droughts);managing interstate agreements, compacts, court decrees, and other legal obligations;and tracking streamflow in major river basins and across borders.
