Title	Groundwater Monitoring
Lead	U.S. Bureau of Reclamation [USBR]
Description	The SJRRP has installed 211 groundwater monitoring wells with 48 locations measuring groundwater temperature. Most monitoring wells are manually measured weekly and results from fourteen key monitoring wells are available online. Groundwater levels in many of these wells will be measured electronically at a high frequency (hourly) and manual measurements will be made periodically to assure the quality of data recorded by the instruments. Generally weekly/monthly manual groundwater level measurements will be made, with more frequent weekly measurements made in priority wells. Several key wells will be telemetered, transmitted real-time to a central database, and posted on CDEC, with links from the SJRRP website (restoresjr.net).

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	California Irrigation Management Information System [CIMIS]
Lead	California Department of Water Resource [DWR]
Description	The California Irrigation Management Information System (CIMIS) is a program unit in the Water Use and Efficiency Branch, Division of Statewide Integrated Water Management, California Department of Water Resources (DWR) that manages a network of over 145 automated weather stations in California. CIMIS was developed in 1982 by DWR and the University of California, Davis (UC Davis). It was designed to assist irrigators in managing their water resources more efficiently. Efficient use of water resources benefits Californians by saving water, energy, and money.

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.

Title	Water Conservation and Production Reports
Lead	California State Water Resources Control Board [SWRCB]
Description	Since June 2014, the State Water Board has been tracking water conservation for each of the state's 409 larger urban water suppliers (those with more than 3,000 connections) on a monthly basis with a goal of documenting the reduction in water use. Water "production" is defined as urban water deliveries to customers. Conservation is calculated over time by reduced deliveries. The program has not been mandatory since 2017. However, many of the urban suppliers have continued to report on a voluntary basis. There is an effort to consolidate and streamline reporting under AB 1668 and SB 606 that will likely replace this system of reporting.

Title	National Water Use Science Project [NWUSP]
Lead	U.S. Geological Survey [USGS]
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	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.
