Title	Juvenile Salmonid Monitoring - Red Bluff Diversion Dam
Lead	U.S. Fish and Wildlife Service [USFWS]
Description	The Red Bluff Fish and Wildlife Office (RBFWO) established a juvenile fish monitoring program using rotary-screw traps at the Red Bluff Diversion Dam (RBDD) in 1994. The primary objectives of this project at present are to (1) obtain juvenile winter Chinook production indices and to correlate these indices with estimated escapement from adult estimates provided by the winter Chinook carcass survey, (2) define seasonal and temporal patterns of abundance of winter, spring, fall and late-fall run Chinook salmon and steelhead trout passing RBDD and (3) obtain relative abundance information (catch per unit volume) for green sturgeon and lamprey to monitor trends in abundance.

Title	Yolo Bypass Fish Monitoring
Lead	California Department of Water Resource [DWR]
Description	California Department of Water Resources (DWR) has operated a fisheries monitoring program in the Yolo Bypass, a seasonal floodplain and tidal slough, since 1998. The objectives of the Yolo Bypass Fish Monitoring Program (YBFMP) are to: (1) collect baseline data on lower trophic levels (phytoplankton, zooplankton, and aquatic insects), juvenile fish and adult fish, hydrology, and water quality parameters;(2) investigation of the temporal and seasonal patterns in chlorophyll-a concentrations, including whether high concentrations are exported from the Bypass during agricultural and natural flow events and the possibility of manipulating bypass flows to benefit listed species like Delta Smelt (Hypomesus transpacificus) and Chinook salmon (Oncorhynchus tshawytscha). The YBFMP operates a rotary screw trap and fyke trap, and conducts biweekly beach seine and lower trophic surveys in addition to maintaining water quality instrumentation in the bypass. The YBFMP serves to fill information gaps regarding environmental conditions in the bypass that trigger migrations and enhanced survival and growth of native fishes, as well as provide data for IEP synthesis efforts.
Science topics	Surface water / flow, Stage, Velocity, Direction, Tides, Flood, Chlorophyll A / B, Phytoplankton, Other zooplankton, Water temperature, Dissolved oxygen, pH, Turbidity, Other discharge contaminants, Mudflats, Intertidal / transition zones, Main channels, Chinook Salmon, Steelhead Trout, Green sturgeon, White Sturgeon, Delta Smelt, Longfin Smelt, Sacramento Splittail, Insects, Striped bass, Conductivity, Saltwater / freshwater marshes, Fish, Invasive / non native species

Title	Continuous Monitoring of Water Quality & Suspended-Sediment Transport [Bay-Delta]
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	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.
Science topics	Water operations / exports, Water storage, Water conveyance / infrastructure, Wastewater discharge, Surface water / flow, Stage, Velocity, Direction, Flood, Main channels, Sloughs, Backwater, Stormwater runoff / drainage, Water use / demand

Title	Assessing sea-level rise and flooding changes in the Sacramento/San Joaquin Delta using historical water-level records
Lead	California State University [CSU]
Description	The project aims to recover, digitize, and analyze more than 1300 station years of ‘lost-and-forgotten’ water level records collected from 1857 to 1982 in the Sacramento-San Joaquin Delta. These measurements, augmented by modern data, will improve our understanding of tidal, flood, and sea level trends in the system. By determining ‘hotspots’ of habitat and flood risk sensitivity, the results may be used to better focus future scientific and management priorities, to protect the environment, manage flood risk, and enhance community resilience to climate change
Science topics	Backwater, Climate change, Environmental drivers, Estuaries, Land elevation, Levees, Outflow, Sea level rise, Stage, Subsidence, Surface water / flow, Tides, Velocity, Vessels and shipping channels, Water, Wind

Title	Continuous Flow and Water Quality Monitoring Network in the Sacramento-San Joaquin Delta
Lead	U.S. Geological Survey [USGS]
Description	This project envisions the continuation, expansion, and further integration of high frequency monitoring for flow, water quality (including chlorophyll and nutrients), sediment, as well as biological responses at key locations in the Delta and Suisun Bay. The physical properties monitored by the fixed-station network are the primary drivers of the habitat conditions and biological responses that management actions hope to achieve. Nutrient dynamics are explicitly measured at select stations to improve our understanding of how physical dynamics, water quality and landscape features shape the base of Delta food webs. These data will provide information about drivers linked to food quantity and quality as well as potential toxins production by harmful algae. Suspended-sediment monitoring provides an understanding of the inputs and internal exchanges between regions, locations of sources and sinks, and provides insight into the underlying cause of turbidity variability in the study area. Suspended-sediment measurements gage the availability of suspended sediment for existing marshes and for proposed large-scale marsh restoration efforts in the Delta. There are a total of 5 sub-tasks in this project: • Task 1: Hydrodynamics Team – Fixed Station Network Operation and Maintenance • Task 2: BioGeoChemistry Team -- Fixed Station Network Operation and Maintenance • Task 3: Delta Sediment Team – Fixed Station Network Operation and Maintenance • Task 4: Bay Sediment Team – Fixed Station Network Operation and Maintenance • Task 5: Project Management
Science topics	Chlorophyll A / B, Conductivity, Dissolved oxygen, Flows, Nutrients, pH, Phytoplankton, Sediments, Stage, Surface water / flow, Tides, Turbidity, Velocity, Water operations / exports, Water temperature
