Dayflow

Dayflow is a computer program developed in 1978 as an accounting tool for determining historical Delta boundary hydrology.  It presently provides the best estimate of historical mean daily flows: (1) through the Delta Cross Channel and Georgiana Slough; (2) past Jersey Point; and (3) past Chipps Island to San Francisco Bay (net Delta outflow). The degree of accuracy of Dayflow output is affected by the Dayflow computational scheme and the accuracy and limitations of the input data. The input data include the principal Delta stream inflows, Delta precipitation, Delta exports, and Delta gross channel depletions. Both monitored and estimated values are included as described in this Dayflow program documentation. Currently, flows are not routed to account for travel time through the Delta. All calculations involving inflows, depletions, transfers, exports, and outflow are performed using data for the same day. All Dayflow summary reports distributed through January 1985, providing flow data through August 1984, and data for September 1984 reported herein were generated according to the algorithm described in the Computational Scheme section.

DWR Community Groundwater Level Monitoring Program

The Community Groundwater Level Monitoring Program is a voluntary, locally driven effort designed to strengthen drought resilience and fill critical groundwater data gaps across the region. The program is built around three complementary components: domestic wells, schools, and small water systems. Community members with domestic wells can participate by collecting simple water-level measurements using equipment and training provided free of charge by the Department of Water Resources (DWR). In exchange, participants agree to submit their data to DWR’s public groundwater databases, helping create a more complete and transparent picture of groundwater conditions in areas where monitoring is limited.

The school and small water system components support implementation of SB 552, which requires improved drought planning and early warning capabilities for vulnerable water supplies. By partnering with schools and small water systems to install dedicated monitoring equipment and collect consistent data, the program provides timely information that can be used for drought preparedness, resource planning, and community outreach. Together, these three components form a flexible, community-centered network that expands groundwater understanding and supports long-term water reliability for all.

Sustainable Groundwater Management Act (SGMA) Water Year Type Dataset

The following dataset has been developed to assist the Groundwater Sustainability Agencies (GSAs) in their water budget development per the Groundwater Sustainability Plan Regulations §354.18. GSAs may choose to use this dataset but are not required. GSAs have the option to develop their own water year types based on best available data. For information on how the SGMA Water Year Type Dataset was developed, please see the SGMA Water Year Type Dataset Development Report.

Questions or comments can be directed to the Sustainable Groundwater Management Office at sgmps@water.ca.gov.

Scripps's Murrelet Range - CWHR B241 [ds1510]

<div style='text-align:Left;'><div><div><p style='margin:0 0 14 0;'><span><span>Vector datasets of CWHR range maps are one component of California Wildlife Habitat Relationships (CWHR), a comprehensive information system and predictive model for California's wildlife. The CWHR System was developed to support habitat conservation and management, land use planning, impact assessment, education, and research involving terrestrial vertebrates in California. CWHR contains information on life history, management status, geographic distribution, and habitat relationships for wildlife species known to occur regularly in California. Range maps represent the maximum, current geographic extent of each species within California. They were originally delineated at a scale of 1:5,000,000 by species-level experts and have gradually been revised at a scale of 1:1,000,000. For more information about CWHR, visit the CWHR webpage (</span><a href='https://www.wildlife.ca.gov/Data/CWHR' style='text-decoration:underline;' rel='nofollow ugc'><span>https://www.wildlife.ca.gov/Data/CWHR</span></a><span>). The webpage provides links to download CWHR data and user documents such as a look up table of available range maps including species code, species name, and range map revision history; a full set of CWHR GIS data; .pdf files of each range map or species life history accounts; and a User Guide.</span></span></p></div></div></div>

Groundwater Trading

The Water Resiliency Portfolio (2020) tasked the four State agencies to “create flexibility for GSAs to trade water within basins by enabling and incentivizing transactional approaches, including groundwater markets, with rules that safeguard natural resources, small- and medium-size farms, and water supply and quality for disadvantaged communities.” This direction is spelled out as Action 3.6. In 2021, the California Water Commission (Commission) was tasked to take initial steps to advance Action 3.6, and in 2022, the Commission's White Paper (https://cwc.ca.gov/-/media/CWC-Website/Files/Documents/2022/05_May/May2022_Item_10_Attach_1_WhitePaper_Final.pdf) identifies potential State actions and suggests that “with DWR as the lead agency, [the four State agencies] develop a workplan for implementing Action 3.6…”.

This data is current as of October 13, 2025. The file is in ESRI geodatabase format and is intended for use with compatible GIS software. Groundwater basins are represented as polygon features and designated on the basis of geological and hydrological conditions - usually the occurrence of alluvial or unconsolidated deposits. When practical, large basins are also subdivided by political boundaries, as in the Central Valley. Basins are named and numbered per the convention of the Department of Water Resources.</span></span></p>

2025 UWMP Reporting

This DWR Open Data Publication includes the necessary reporting materials to complete the 2025 Urban Water Management Plan (UWMP). Urban Water Management Plans (UWMPs) are prepared by urban water suppliers every five years. These plans support the suppliers’ long-term resource planning to ensure that adequate water supplies are available to meet existing and future water needs.

The publicly available PDF files include the Final 2025 UWMP Guidebook and Appendices A through P. 

The requirements for UWMPs are found in two sections of California Water Code, §10610-10656 and §10608.  Every urban water supplier that either provides over 3,000 acre-feet of water annually, or serves more than 3,000 urban connections is required to submit an UWMP.
Find more information here: https://water.ca.gov/Programs/Water-Use-And-Efficiency/Urban-Water-Use-Efficiency/Urban-Water-Management-Plans

Once the reporting process is complete in 2026 calendar year, the five-year period reporting datasets for all Urban Water Suppliers made available here.
