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.

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

This is a shapefile of the streamflow network. This dataset contains the SFR segment and reach data along with the non-calibrated Streamflow-Routing (SFR) package parameter values.

This data release contains a shapefile of streamflow gage locations in the Russian River watershed and an excel document with the daily timeseries of streamflow for these gages.

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

This shapefile is 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.

This data release contains 2 shapefiles used in the Russian River Integrated Hydrologic Model (RRIHM). These shapefiles are: 1) groundwater wells (with measured ground water levels), and 2) streamflow gages. It also includes a comma separated values (CSV) file of measured daily streamflow (in cubic feet per second).

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.

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) Reference: Harbaugh, A.W., 2005, MODFLOW-2005, the U.S. Geological Survey modular ground-water model -- the Ground-Water Flow Process: U.S. Geological Survey Techniques and Methods 6-A16. https://doi.org/10.3133/tm6A16 Konikow, L.F., Hornberger, G.Z., Halford, K.J., and Hanson, R.T., 2009, Revised multi-node well (MNW2) package for MODFLOW ground-water flow model: U.S. Geological Survey Techniques and Methods 6–A30, 67 p.
