Russian River Integrated Hydrologic Model (RRIHM): Wells

The Russian River Watershed (RRW) covers about 1300 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 part of the larger Russian River Integrated Hydrologic Model (RRIHM) community of data releases (https://www.sciencebase.gov/catalog/item/62ffdd40d34ed6dc55924a4b). It contains 4 shapefiles and a comma separated values (.csv) file. The data release includes municipal and industrial wells represented in the MODFLOW Multi-Node Wells package, along with rural domestic wells represented in the MODFLOW Wells package (Harbaugh, 2005; Konikow, L.F., et al., 2009)
