This data was created to depict portions of state-owned Sovereign Lands that are under the jurisdiction of the California State Lands Commission. Data coverage is currently limited to reaches 1A, 4A and 4B1 of the San Joaquin River, other sections are pending survey or digitization.

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).

The California State Lands Commission (CSLC) may issue leases or permits on state lands under its jurisdiction. Additional information regarding CSLC leasing can be found at: https://www.slc.ca.gov/leases-permits/. This is a point feature dataset indicating the approximate locations, often represented by a center point, of the general lease area of lands leased by the CSLC on state sovereign lands and school lands, including coastal marine areas, bays, rivers, and lakes. This dataset is to be considered incomplete as new leases are being entered into the CSLC database, and existing leases are modified or terminated, on an ongoing basis. Many marine areas, bays, rivers, and lakes are not under the leasing jurisdiction of the CSLC because they have been legislatively granted in trust to other government entities. Additionally, some leases are not shown at all for a variety of reasons. Many point features in this dataset provide links to maps and/or land descriptions used in the CSLC lease approval process. These documents are hosted on the CSLC archives website at https://www.slc.ca.gov/archives/. In some cases, these documents provide reliable, current lease boundary information, while in other cases, additional information is necessary to properly define lease boundaries. Additionally, revisions to lease boundaries may have occurred subsequent to CSLC approval, as in the case of as-built locations that differ from originally approved alignments. Further, the boundary of some leases may be the mean high tide line, which in a state of nature is both ambulatory, and in the absence of a survey conducted by a licensed land surveyor, not readily locatable.,

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.
