The Russian River Watershed (RRW) covers about 1,300 square miles (without Santa Rosa Plain) of urban, agricultural, and forested lands in northern Sonoma County and southern Mendocino County, California. Communities in the RRW depend on a combination of Russian River water and groundwater to meet their water-supply demands. Water is used primarily for agricultural irrigation, municipal and private wells supply, and commercial uses - such as for wineries and recreation. Annual rainfall in the RRW is highly variable, making it prone to droughts and flooding from atmospheric river events. In order to better understand surface-water and groundwater issues, the USGS is creating a Coupled Ground-Water and Surface-Water Flow Model (GSFLOW; Markstrom and others, 2008) of the RRW. This model will include climate, geology, surface-water, groundwater, and land-use data.
This data release is a shapefile of the 2014 agricultural fields from the California Department of Water Resources intersected with the Russian River Integrated Hydrologic Model (RRIHM) grid. Spatially, this data shows the boundaries of the 2014 agricultural fields with the model grid dissected into the fields. The shapefile attribute table shows the data from both the agricultural fields and the model grid shapefiles. The RRIHM grid can be found in it's own data release on the Russian River Integrated Hydrologic Model (RRIHM) Coupled Ground-Water and Surface-Water Flow Model Science Base community page.
