The feature dataset contains storm water projects planned in the future throughout California that involve groundwater recharge and direct use. It was used to develop storm water targets for the years 2020 and 2035 per directives to DWR in California Water Code Section 10608.50 (b). As of February 2018, projects included are those proposed to be constructed post 2014. Information from various databases was used to compile the project database. More details can be found in Appendix A of the DWR report “Determination of New Statewide Stormwater Targets for Groundwater Recharge and Direct Use Benefitting Urban Water Supply”. Expected public release: March 2018.

The feature datasets contain Phase 1 and Phase 2 municipal separate stormwater sewer system (MS4s) permittees in California. These draft layers are based on 2010 census data and they have not been updated since 2013 and there are no current plans to include them as a SWRCB web service. Most of the Phase 1 permittees encompass an entire metropolitan area. The Municipal Storm Water Program manages the Phase I Permit Program (serving municipalities over 100,000 people), the Phase II Permit Program (for municipalities less than 100,000), and the Statewide Storm Water Permit for the State of California Department of Transportation. The State Water Resources Control Board (State Water Board) and Regional Water Quality Control Boards (collectively, the Water Boards) implement and enforce the Municipal Storm Water Program.

This is a point feature class of all groundwater elevation monitoring stations (wells) maintained in the California Department of Water Resources’ (hereafter the Department) Enterprise Water Management database. Individual station information comes from a wide variety of sources, including and local and federal agencies, that conduct groundwater elevation monitoring within the state of California.

This dataset depicts contours of estimated change in groundwater piezometric surfaces in the unconfined or uppermost semi-confined aquifers, between two specified years, by season. Contours represent change in groundwater level (depth) by year and season (fall or spring). The contour interval is 10 ft.

This dataset depicts change in groundwater level at selected monitoring locations (wells) between two specified years, by season. Change values represent change in groundwater level (elevation) by year and season (fall or spring). Other information on the monitoring location is also included. Positive values indicate groundwater has risen (groundwater surface elevation has increased) from the early year to the late year, while negative values indicate groundwater level surface has fallen (decreased in elevation ) from the early year to the late year. Water level monitoring locations and measurements used are selected based on measurement date and well construction information, where available, and approximate groundwater levels in the unconfined to uppermost semi-confined aquifers.

Sustainable Groundwater Management Act (SGMA) 2019 Basin Prioritization for California's 515 groundwater basins. Groundwater basin geometry from i08_B118_CA_GroundwaterBasins joined to i08_ B118_SGMA_2019_Basin_Prioritization table, and then exported to create this feature class. The final results of SGMA 2019 Basin Prioritization were released on December 6, 2019.
