2011 and 2012 Georgiana Slough Non-Physical Barrier Performance Evaluation - GSNPB-12_Legacy_Reports v2

DWR implemented a large-scale experimental testing program in 2011 and 2012 to assess the effectiveness of a non-physical barrier as a method for guiding downstream migrating juvenile salmonids. The experimental design of the 2011 and 2012 tests included the use of acoustically tagged juvenile late fall-run Chinook salmon (2011 and 2012) and steelhead (2012), released upstream of the nonphysical barrier when the barrier was on and when it was off, to determine the effectiveness of the barrier. This report presents the results of the experimental tests conducted in 2012 with additional discussion of the results of tests conducted at Georgiana Slough in spring 2011.

California Central Valley Groundwater-Surface Water Simulation Model – Fine Grid (C2VSimFG)

## C2VSimFG Version 1.5

(Released on June 6, 2025) Version 1.5 of the California Central Valley Groundwater-Surface Water Simulation Model – Fine Grid (C2VSimFG) is a major update to Version 1.01, which was released in April 2021.
C2VSimFG is a numerical model developed by the California Department of Water Resources (DWR) to simulate the movement of water through the linked land surface, groundwater, and surface water flow systems of California’s Central Valley. The model is built using DWR’s Integrated Water Flow Model Version 2024 (IWFM-2024.2.1594).
Version 1.5 includes updated monthly historical data for stream inflows, surface water diversions, precipitation, evapotranspiration, and land use from October 1973 through September 2021. It dynamically estimates crop water demands and determines how those demands are met through contributions from precipitation, soil moisture, and surface water diversions, calculating the groundwater pumping required to meet any remaining demand. The model simulates the historical response of the Central Valley’s water system to observed stresses and can also be used to evaluate responses to future conditions.
DWR makes C2VSimFG Version 1.5 available as an optional tool for Groundwater Sustainable Agencies and other interested parties engaged in developing and implementing Groundwater Sustainability Plans under the Sustainable Groundwater Management Act.

## C2VSimFG Web Application

California Central Valley Groundwater–Surface Water Simulation Model—Fine Grid (C2VSimFG) Web Application, an interactive online tool for exploring outputs from C2VSimFG Version 1.5. Released on April 30, 2026, the application provides users with streamlined access to simulation results from the updated C2VSimFG version 1.5.
Developed for Groundwater Sustainability Agencies (GSAs) and interested parties, the application is designed to support users with little to no modeling experience in exploring and analyzing C2VSimFG results. Through a user-friendly interface, the web application enables users to visualize model outputs without running the model by generating hydrographs, water budgets, and zonal budget charts on demand using the latest simulated results.
The application also allows users to compare simulated outputs with compiled historical observation data from Water year 1974 through 2021, providing additional context for evaluating model performance.

**Note:** This dataset was previously available via the BLM Navigator system, which was decommissioned in 2022 and replaced by the BLM GBP Hub. The California-specific Wilderness Study Areas polygon arcs dataset is not currently accessible on the replacement platform. For current data availability, contact BLM California at BLM_CA_Web_SO_GIS@blm.gov.

BLM CA Land Status Surface Management Agency

The Surface Management Agency (SMA) Geographic Information System (GIS) dataset depicts Federal land for the United States and classifies this land by its active Federal surface managing agency. A Federal SMA agency refers to a Federal agency with administrative jurisdiction over the surface of Federal lands. Jurisdiction over the land is defined when the land is either: Withdrawn by some administrative or legislative action, or Acquired or Exchanged by a Federal Agency. The GIS data contained in this dataset represents the polygon features that show the boundaries for Surface Management Agency and the surface extent of each Federal agency's surface administrative jurisdiction. SMA data depicts current withdrawn areas for a particular agency and (when appropriate) includes land that was acquired or exchanged and is located outside of a withdrawal area for that agency. The SMA data do not illustrate land status ownership pattern boundaries or contain land ownership attribute details. The LND_SurfaceEstate data is edited and maintained in a single polygon feature class. Whenever possible, BLM lands are constructed from the Public Land Survey System (PLSS). Alignment of BLM data with the PLSS is a continual process, as the accuracy and density of PLSS data continues to improve and develop. Issues of misalignment with the PLSS are more common with non-BLM management areas. These discrepancies are being addressed at the BLM California State office based on U.S. Department of Interior priorities throughout the State of California.

This dataset is linked to the CNRA Open Data Platform from the BLM Geospatial Business Platform (GBP) Hub as the California-specific version of the national Surface Management Agency dataset.

BLM CA Land Use Planning Area Boundary Polygons

This polygon feature class shows the boundaries for anticipated, in-progress, existing, and historic BLM Land Use Planning Areas (LUPAs) in California. Land Use Planning Areas are geographic areas within which BLM makes resource management decisions during a land use planning effort. A LUPA shifts from 'in-progress' to 'existing' status when the Land Use Plan is approved and a Record of Decision (ROD) date is established, at which point the previous plan is moved to a 'historic' status. 

This California state dataset is part of the national BLM Land Use Planning Area dataset hosted on the BLM GBP Hub. Data are maintained by the BLM California State Office and updated per the national data standard schedule.
