Kentucky Rivers

Miles along rivers and streams in the National Hydrologic Database (NHD) with a valid Geographic Naming Information System (GNIS) name and code. Many agencies in the Commonwealth of Kentucky use river mile points in various regulatory programs. This data set was built to provide these agencies with a consistent and more precise source of river miles.

Dye traces in karst areas of Kentucky. Associated layers include injection and recovery points, flow paths, inferred ground-water basins, sinking streams, and intermittent lakes.  Created at a scale of 1:100,000.  Should only be used for general guidance at larger scales.

These data were developed as a subset of the 24k NHD Blueline Streams. An additional field indicating whether the segment falls under the river miles included by USACE in public notice has been added. 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 USGS National Water Information System (NWIS) contains and provides access to inventory information about sites at stream reaches, wells, test holes, springs, tunnels, drains, lakes, reservoirs, ponds, excavations, and water-use facilities.Information for each site in the USGS data base can be retrieved for viewing and for download and import into other software, including GIS software. Includes links to all water data available for individual sites. Download Link: https://ky.box.com/v/kymartian-nwis-locations
