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.

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 (elevation) by year and season (fall or spring). The contour interval is 10 ft. The contours represent lines of equal change in groundwater level surface. 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. For 'Elevation' type contours, contours represent lines of equal elevation of the estimated groundwater level surface above mean sea level. Higher contour values indicate higher elevations of the estimated groundwater level. Water level measurements used for contouring are selected based on measurement date and well construction information, where available, and approximate groundwater levels in the unconfined to uppermost semi-confined aquifers.

,The Central Valley Flood Protection Plan (CVFPP) recommends that the California Department of Water Resources (DWR) develop a system for tracking performance of the flood system, including the following actions:,• Track the outcomes from flood investments to demonstrate value.,• Monitor and track outcomes of multi-benefit projects over time.,• Create a tracking system of operations and maintenance investments and outcomes to demonstrate the value that Local Maintaining Agencies attain for their investments.,• Track and report changes in the hydrologic and sea level rise conditions and subsidence over time through updates to the Flood System Status Report (FSSR),These recommendations stem from progressive work during the development of the 2012 CVFPP and subsequent 2017 CVFPP update. The DWR Flood Performance Tracking System tracks the CVFPP outcomes related to: (1) improving flood risk management and (2) enhancing ecosystem vitality. This tracking system has the ability to track the status, trends, and changes over time of the ecosystem (including the Conservation Strategy’s Measurable Objectives [CSMOs] as of 2016) outlined in the Conservation Strategy document here: https://cawaterlibrary.net/wp-content/uploads/2017/10/ConservStrat-Nov2016.pdf along with the Flood System metrics outlined in the Flood System Status Report here: https://water.ca.gov/Programs/Flood-Management/Flood-Planning-and-Studies/Central-Valley-Flood-Protection-Plan.,The associated data are considered DWR enterprise GIS data, which meet all appropriate requirements of the DWR Spatial Data Standards, specifically the DWR Spatial Data Standard version 3.1, dated September 11, 2019.,This data set was not produced by DWR. Data were originally developed and supplied by ESA, under contract to California Department of Water Resources.

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.

Developed exclusively for Central Valley Flood Protection Plan (CVFPP) work. Specifically, this area has been delineated in an effort to define the analysis area for environmental analyses of various kinds. Once finalized, a two-mile buffer will be added and form the basis of the potential environmental impacts delineation for CEQA work. Systemwide Planning Area includes lands subject to flooding under the current facilities and operation of the Sacramento-San Joaquin River Flood Management System CWC§ 9611, CWC§ 9641(d, e) (completely contains the State Plan of Flood Control (SPFC) Planning Area). The CVFPP describes facilities and flood management problems in this area and proposes solutions, while not extending the State's responsibility (CWC§ 9603(b)). This feature class represents the Systemwide Planning Area. It is one of the three CVFPP Planning Areas. It is comprised of the following layers:,

From the DAU boundaries in i03_DAU_county_cnty24k09 dataset: “Detailed Analysis Unit-(DAU) Convergence via County Boundary cnty24k09_1_poly, (*See metadata for CAL-FIRE cnty24k09_1_poly), State of California. The existing DAU boundaries were extracted via cnty24k09_1_poly, Northern Region Office (NRO) via ArcMap 10.1. DAU’s were sent out to: Northern Region Office (NRO), North Central Region Office (NCRO), South Central Region Office (SCRO) and Southern Region Office (SRO) respectively. Collaboration by Department of Water Resources, Region Office personnel, Michael L. Serna, NRO, Jason Harbaugh - NCRO, Cynthia Moffett - SCRO and Robert Fastenau - SRO with the final merge of all data into a cohesive feature class. This version was derived because a preexisting “dau_v2_105 nad27” Detailed Analysis Unit feature class that contained a multitude of variant sliver acreages along all DAU and county boundary lines through-out the State of California. Each Region Office was sent their respective features where they exposed the DAU’s sliver anomalies. They subsequently merged the variant slivers into the proper DAUs. Upon completion, the DAU feature classes were sent back for assemblage. These features are reachable by County\DAU. This allows the county boundaries, the DAU boundaries and the State of California Boundary to match Cal-Fire cnty24k09_1_poly.”
