ACE addresses both terrestrial and aquatic data. The ACE model combines and analyzes terrestrial information in a 2.5 square mile hexagon grid and aquatic information at the HUC12 watershed level across the state to produce a series of maps for use in non-regulatory evaluation of conservation priorities in California. The model addresses as many of CDFWs statewide conservation and recreational mandates as feasible using high quality data sources. High value areas statewide and in each USDA Ecoregion were identified. The ACE maps and data can be viewed in the ACE online map viewer, or downloaded for use in ArcGIS.

Water Plan Water Balance Data

Department of Water Resources California Water Plan program computes applied, net, and depletion water balances for California. Water balances are simplified water budgets for a water year based on analyses of developed and dedicated water supplies, water uses by sector, water reuses, operational characteristics for an area, and inflows and outflow for a study area that occur above the root zone.  Dedicated and developed water supplies include surface water, groundwater, reused and recycled water.  Water uses by sector for these analyses include parameters for agriculture, urban, managed wetlands, Wild and Scenic river annual volumes, minimum required instream flows, and minimum required delta outflow, recognizing that water is often used multiple times and benefits multiple sectors. Water balance results show what water was applied to actual uses so that use equals supply.  Recent data provided includes water uses and supplies for WYs 2002-2022 at Detailed Analysis Unit by County (DAUCO), Planning Area (PA), Hydrologic Region (HR), and Statewide spatial scales. Computation and aggregation equations for applied, net, and depletion water balances are included in the Standard Operating Procedures (SOPs) for data management and analyses.  Zipped data files are in .CSV format. 

The California Water Plan Update 2023 Water Balances Supporting Document includes water use and supply discussion, graphics, and links to files and folders of water use and supply data for 1998-2020, and related information.  The Update 2023 Standard Operating Procedures (SOPs) for Water Balances Automation includes detailed technical information, diagrams, equations, controlled vocabulary, and definitions.  

California Water Plan Update 2028 is underway and will include data through WY 2024.

California Groundwater Elevation Monitoring (CASGEM) Program

Since 2009, the [California Statewide Groundwater Elevation Monitoring (CASGEM) Program](https://water.ca.gov/programs/groundwater-management/groundwater-elevation-monitoring--casgem) has tracked seasonal and long-term groundwater elevation trends in groundwater basins statewide. 

The program’s mission is to establish a permanent, locally-managed program of regular and systematic monitoring in all of California's alluvial groundwater basins. 

Senate Bill x7-6, passed by the legislature in 2009, established collaboration between local monitoring parties and DWR to collect statewide groundwater elevations, to be made available to the public. In response to the law, we developed the CASGEM program. 

Collecting and evaluating these groundwater data on a statewide scale is a fundamental step toward improving management of California's groundwater resources. The CASGEM program relies and builds upon the many previously established local long-term groundwater monitoring and management programs. Our role is to coordinate the CASGEM program, to work cooperatively with local entities, and to maintain the collected elevation data in a readily and widely available public database.

Earthquake Zones of Required Investigation Maps and Reports

<p style='text-align:justify;'>The Alquist-Priolo Earthquake Fault Zoning Act (1972) and the Seismic Hazards Mapping Act (1990) direct the State Geologist to delineate regulatory &quot;Zones of Required Investigation&quot; to reduce the threat to public health and safety and to minimize the loss of life and property posed by earthquake-triggered ground failures. Cities and counties affected by the zones must regulate certain development &quot;projects&quot; within them. These Acts also require sellers of real property (and their agents) within a mapped hazard zone to disclose at the time of sale that the property lies within such a zone. </p><p style='text-align:justify;'>Fault Evaluation Reports are available for those areas covered by a Regulatory Map however there are reports available for areas outside the Regulatory map boundary.
