This dataset is a feature class identifying all dams currently under the jurisdiction of the Division of Safety of Dams (DSOD). The dataset is extracted from DSOD internal records and contains basic information about the dam including the type of construction, basic dimensions such as height, length, and maximum storage capacity; abbreviated owner information to identify the entity legally responsible for the dam; an assessment of the downstream hazard associated with the dam; an assessment of the current condition of the dam; and indication as to whether the dam is operating at a restricted storage level. Several dams span rivers that define county boundaries, so DSOD references the right abutment of the dam to identify the location of the structure and to associate it with a singular administrative subdivision 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:,

This feature class represents the Systemwide Planning Area. It is one of the three Central Valley Flood Protection Plan (CVFPP) Planning Areas. It is comprised of the following layers:Below are layers that delineate the boundary.1. Levee Flood Protection Zones (LFPZs) developed by DWR as a first estimate of areas potentially inundated due to State Plan of Flood Control (SPFC) levee failure. There are no frequencies associated with these areas. LeveeFloodProtectionZone_20100301 (DWR)2. Comprehensive Study 500 year floodplain delineation (CS_FP_500YR_Dissolve.shp) (DWR)3. 200 year floodplain developed by DWR for the reaches of the Sacramento River upstream of Woodson Bridge which was the limit of the floodplain development for the Comprehensive Study. DWR_FloodPlain_200YR (DWR)4. American River Economic Reevalulation Report (ARERR) 500 Year Floodplain.5. legal_delta.shp6. A 50ft buffer of streams defining the hydrologic connections between multi-purpose or dedicated flood control reservoirs within the WPA.7. Added the multipurpose/Flood Control Reservoirs (MultipurposeReservoirs_20100902.shp)8. If Hydrologic features (Rivers, Channels, bypasses, etc) have SPFC Project levees on BOTH sides of the features… Include areas between two levees.9. If Hydrologic features (Rivers, Channels, bypasses, etc) have SPFC Project levees on ONE sides of the features… Include areas from centerline of the feature to the levees.10. Middle Creek, Adin, and North Fork Feather River project have been added.11. HEC-FDA Impact Areas (the latest version developed with no holes/overlaps) were added as a way of filling in and smoothing the ragged boundaries of the Comprehensive Study 500yr Floodplain.12. Data holes were filled using an automated process and supplemented by visual inspection and manual additions/subtractions.13. Added USACE (Sacrametonto Office - SPK) provided protection areas that intersected the existing SPA except those outside of the Sacramento and San Joaquin Hyrdologic Regions (as defined by CA DWR CalWater 2.2).

,This is a line dataset that delineates the extent of State Water Project construction divisions. The locations of the construction divisions were derived from DWR records.,This dataset is current as of 3/20/2024.,

Dataset represents centerlines of major water project canals that are managed by local area government agencies or entities. This dataset does not contain major State or Federal canals. The original data were from many sources including NHD,USBR,DWR, and contained errors in the attributes and locations. These errors were rectified by Jeff Galef of DWR Delta Levees Special Investigations Branch, using 2005 and 2006 NAIP imagery and Central Valley Aerials Express. These updates were as of 2009. Conflicts between this original data source and any new linework added was resolved using NAIP imagery from 2012. Digitizing was done at approximately 1:9000 scale. Many unnamed canals were identified using USGS topo maps and ESRI Street Map. Additional canal features were added in November 2017 which were inadvertently not included in the initial dataset.

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 document provides a map of California and at each county a pie-chart depicts the proportion of utility-scale electrical production capacity coming from small or large hydroelectric facilities. The second page provides the same county-level data except each county's total hydroelectric capacity (megawatts) is also given. The total statewide capacity generated from these sources is depicted as well as the total contribution from each source. All data is from 2019.
