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.

Division of Water (DOW) Priority Watersheds receive greater consideration for funding and technical support in state agency programs, including USEPA 319 (Nonpoint Source) Grant Program Funding, state revolving funds for water and wastewater infrastructure, and state agricultural cost-share programs. DOW Priority Watersheds are distributed throughout the state, consisting of both 319 Program Basin Priorities, and Nutrient Priorities. Each DOW Priority area is scaled to a HUC-12 watershed. These focused investment areas consisting of both 319 Program Basin Priorities, and Nutrient Priority Areas.  Basin Priorities reflect areas with a demonstrated need for investment (impaired waters, environmental justice considerations, TMDLs, nutrient priorities, sourcewater, or local high-quality waterways), and sufficient local capacity (watershed plans) to improve water quality.  Nutrient Priorities reflect areas of high aquatic nutrient concentrations (yields), locations of repeat confirmed Harmful Algal Blooms (HABs), and sensitive drinking water sources.  Combined, these two data sets represent a data-driven prioritization effort to address specific local water quality needs.

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 layer includes data that identifies compensatory mitigation projects in the Commonwealth. These projects are restorations of streams or wetlands performed to compensate for unavoidable impacts to streams and wetlands. The project areas are protected in perpetuity and are either under construction, monitoring post construction or have been released from monitoring and considered stable. Active and released mitigation sites.

Section 305(b) of the Clean Water Act requires states to assess the condition of the Waters of the US. The Kentucky Division of Water, in cooperation with other agencies, collects biological and water quality data to assess the condition of the resource and reports this to Congress every two years in the Integrated Report to Congress. (https://eec.ky.gov/Environmental-Protection/Water/Monitor/Pages/IntegratedReportDownload.aspx) These data represent the assessment results for surface waters of the Commonwealth of Kentucky.

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.
