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. These data are daily maximum and minimum temperature data from 8 stations in the Russian River watershed for 1990-2015.

This dataset provides crop coefficients from the Sonoma County water agency. Crop coefficients are used to estimate the water requirements of different crops and are essential for efficient irrigation management. The data in this dataset can be used by farmers and water managers to optimize water use and improve crop yields in Sonoma County.

These climate data are temperature, precipitation, solar radiation, and reference evapotranspiration observations from stations in the Russian River watershed. These data were used for the Russian River Integrated Hydrologic Model (RRIHM).

There is one station for each of the 15 zones in the Russian River Integrated Hydrologic Model (RRIHM).

This data release is a shapefile of USGS streamgage locations in the Russian River watershed and the outflow point of the Russian River.

This dataset provides a shapefile of the surface water diversions to agricultural ponds in the Russian River Coupled Groundwater and Surface-Water Flow Model (GSFLOW) model.

This data release is a subset of the National Hydrography Dataset (NHD) flowlines covering the Russian River watershed and the Russian River Integrated Hydrologic Model (RRIHM). The majority of this metadata was modified from the source metadata. Abstract from the NHD metadata: The National Hydrography Dataset (NHD) is a feature-based database that interconnects and uniquely identifies the stream segments or reaches that make up the nation's surface water drainage system. NHD data was originally developed at 1:100,000-scale and exists at that scale for the whole country. This high-resolution NHD, generally developed at 1:24,000/1:12,000 scale, adds detail to the original 1:100,000-scale NHD. (Data for Alaska, Puerto Rico and the Virgin Islands was developed at high-resolution, not 1:100,000 scale.) Local resolution NHD is being developed where partners and data exist. The NHD contains reach codes for networked features, flow direction, names, and centerline representations for areal water bodies. Reaches are also defined on waterbodies and the approximate shorelines of the Great Lakes, the Atlantic and Pacific Oceans and the Gulf of Mexico. The NHD also incorporates the National Spatial Data Infrastructure framework criteria established by the Federal Geographic Data Committee. The National Hydrography Dataset is a comprehensive set of digital spatial data that encodes information about naturally occurring and constructed bodies of water, paths through which water flows, and related entities. The information encoded about features includes a feature date, classification by type, other characteristics, a unique common identifier, the feature length or area, and (rarely) elevation of the surface of water pools and a description of the stage of the elevation. For reaches, encoded information includes a reach code. Names and their identifiers in the Geographic Names Information System, are assigned to most feature types. The direction of flow is encoded for networked features. The data also contains relations that encode metadata, and information that supports the exchange of future updates and improvements to the data. The names and definitions of all feature types, characteristics, and values are in the Standards for National Hydrography Dataset: Reston, Virginia, U.S. Geological Survey, 1999.
