Summary

The shapefile in this data release is the updated Central Valley Hydrologic Model (CVHM2) model grid cells with yearly land use from 1921 to 2019. Historical land use data shows the Central Valley land use prior to agricultural development. The rise of agriculture in the Central Valley is visible over time in this data set. Existing land use maps covering the Central Valley were used as sources and were assigned to model grids cells for their observed land use year. This source data was used to estimate land use over time for years where no land use map was available. This was accomplished by comparing land use cells between two years where source data is available. Cells where there is no land use change remain the same and are assigned [...]

Purpose

Historical land use data was collected for the updated Central Valley Hydrologic Model (CVHM2). Data covering the entire model area for years 1874 and 1945 was obtained from California State University Chico, and the United States Bureau of Reclamation, respectively. Additionally, county level land use updates were made for the following counties for the specified years using data from the California Department of Water Resources (DWR) Land Use Survey: Butte (2004), Sutter (2004), Yuba (2005), Kern (2006), Tulare (2007), Yolo (2008), East Fresno (2009), and Madera (2011). Non-DWR datasets were classified for CVHM2 using the 12 DWR class-1 categories, and the augmented general classes used by the original Central Valley Hydrologic Model (Faunt and others, 2009). This data set can be used to visualize land use trends in the Central Valley.
