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	National Water Level Observation Network [NWLON]
Lead	National Oceanic and Atmospheric Administration [NOAA]
Description	NOAAâ€™s Center for Operational Oceanographic Products and Services (CO-OPS) maintains the National Water Level Observation Network (NWLON), an observation network with more than 200 permanent water level stations on the coasts and Great Lakes. CO-OPS maintains three core observation and one modeling system. The National Water Level Observation Network (NWLON) is the foundation of the comprehensive system for observing, communicating, and assessing the impact of changing water levels nationwide. This system allows NOAA to provide the official tidal predictions for the nation. Accurate water level data is critical for safe and efficient marine navigation and for the protection of infrastructure along the coast. The NWLON also provides the national standards for tide and water level reference datums used for nautical charting, coastal engineering, international treaty regulation, and boundary determination. The NWLON is also widely recognized as the key federal component of the Integrated Ocean Observing System (IOOS).

Title	Local Maintaining Agency Annual Reporting
Lead	California Department of Water Resource [DWR]
Description	Additions to the Water Code include requirements for local levee maintaining agencies (Local Agencies) to submit to DWR, by September 30 each year, specific information relative to the Project Levees they operate and maintain. Local Agencies who maintain either (1) Project Levees or (2) Non-Project Levees that also benefit land within the boundaries of an area benefited by a Project Levee, are required to submit five categories of information annually. A Local Agency responsible for operation and maintenance of a levee not otherwise subject to these requirements may voluntarily prepare and submit to DWR or the CVFPB a flood management report for website posting The Flood Project Integrity and Inspection Branch (FPIIB) produces annual inspection reports using summarized levee data acquired through the Local Maintaining Agency Reporting Program.
Science topics	Levees, Stage, Tides, Flood

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	Levee Waterside Erosion Surveys
Lead	U.S. Army Corps of Engineers [USACE]
Description	The USACE, with DWR sponsorship, has contracted for waterside erosion surveys of the Sacramento River system since 1998. As stated earlier, FPIIB began conducting waterside erosion surveys of the San Joaquin River portion of the State-Federal flood protection system Project levees in September of 2006. The primary purpose of these surveys is to: a) inspect the waterside levees for erosion activity, b) document and report new erosion sites, c) document and report the current condition of previously identified erosion sites, and d) rank and rate the severity of erosion sites based upon the findings from the field survey. The USACE and its contractors generate the report on erosion found in the Sacramento River system;FPIIB staff supplements their inspection reports with the USACE data as it becomes available.

Title	Telemetered Stream Gauge Stations [Surface Water Monitoring]
Lead	U.S. Bureau of Reclamation [USBR]
Description	A network of stream gauges record and telemeter river stage information. Flow measurements by field crews help calibrate and confirm calculations. Data from stream gage telemetry requires careful consideration as field conditions and equipment malfunctions can provide erroneous readings. A more accurate assessment of actual flow rates requires a review of the flow record and processing to account for actual conditions.

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	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.

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.

Title	Atmospheric River Reconnaissance
Lead	University of California - San Diego [UCSD]
Description	CW3E works directly with water managers in the West to develop science and tools designed to better prepare for the variability inherent in the western US climate. Atmospheric River (AR) Reconnaissance (AR Recon) campaigns support improved prediction of landfalling ARs on the U.S. west coast. ARs are a type of storm that is key to the region's precipitation, flooding, and water supply. 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	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.

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.
