This dataset is a representation of the boundaries of the dry areas within the original claims (or water-righted areas) sourced from the Truckee River and tributaries, as identified by the U.S. District Court in the Orr Ditch Decree of 1944. The intended use of these data is to assist in identifying the general locations of the dry areas and associated claims, the claim number, and the source map produced by the Nevada Division of Water Resources (NDWR) and the Federal Water Master during the Truckee River Appurtenance Mapping Project. This mapping project was initiated in 1994 and continued into the early 2000's, with the final results being a series of maps identifying the location, size, and associated parcels of each claim of the Orr Ditch Decree, signed by the State Engineer and Federal Water Master. These maps are available on the NDWR website: https://water.nv.gov/RiverMapSearch.aspx. This GIS layer should not be considered a replacement of the signed maps and exists only as guide and starting point to identify the approximate locations of the water-righted areas in comparison to modern parcel boundaries. Further research is required to determine if a particular parcel originally had decreed water rights and has retained those rights. Please contact the Division of Water Resources for more information.
In order to produce a GIS depiction of the dry areas, the final signed maps were georeferenced to the most up-to-date version of Washoe County's parcel dataset. Each claim and associated dry area was then digitized from the boundaries shown on the georeferenced map and attributed with the assigned claim number, a link to the claim on the NDWR Permit Database, the source map number, and a direct link the source map on the NDWR website. As this layer is strictly a visual representation, no attempt was made to match the acreages listed on the source map or in the decree for each claim.

This dataset is a representation of the boundaries of the original claims (or water-righted areas) sourced from the Carson River and tributaries, as identified by the U.S. District Court in the Alpine Decree of 1980. The intended use of these data is to assist in identifying the general locations of the water-righted areas, the associated claim number, and the source map produced by the Nevada Division of Water Resources (NDWR) and the Federal Water Master during the Carson River Appurtenance Mapping Project.

These parcel datasets were provided by the Nevada State Demographer and standardized by the Division of Water Resources to have consistent fields. Not all counties provide a site city or site address. Web links to the county assessor webpage are available for individual parcels to access more detailed information. Esmeralda County does not have digital parcels.

The GIS data for county parcels cannot be shared outside the department as directed by NRS 250.

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.

Major Rivers were extracted from NHD_HydroPoints_USGS by using a definition query: HydroCat = 'River'

The Geographic Names Information System (GNIS) is the Federal standard for geographic nomenclature. The U.S. Geological Survey developed the GNIS for the U.S. Board on Geographic Names, a Federal inter-agency body chartered by public law to maintain uniform feature name usage throughout the Government and to promulgate standard names to the public. The GNIS is the official repository of domestic geographic names data; the official vehicle for geographic names use by all departments of the Federal Government; and the source for applying geographic names to Federal electronic and printed products of all types.
