Geography. The Kentucky River 205 005 watershed lies along the boundary between Clark County and Madison County. The land is in the Bluegrass physiographic region, characterized by hilly or undulating terrain, medium to very rapid rates of surface runoff, and slow to medium groundwater drainage. Parts of the watershed lie over easily weathered clay shales that store water but allow little groundwater flow. There are also areas of interbedded shales and limestones (these are 20% limestone; water conduction is poor because of the clay content of the shale). The rest of the watershed lies above interbedded clay shales and siltstones.

Waterways. This watershed includes the section of the Kentucky River between the Red River and Lower Howard Creek (Lisletown). Among the creeks that feed it are Twomile Creek, Indian Creek, and Bull Run. Water from the Otter Creek, Fourmile Creek, Upper Howard Creek, Red River (lower), and Kentucky River 204 080 watersheds also flow into this watershed.

Land and water use. Land in the watershed is about 70% agricultural and 30% rural and wooded. The surface waters of the watershed supply the drinking water for the municipal system in Winchester. Four businesses and organizations hold permits for discharges into the creeks. See tables for details.

Agency data assessment. The assessed segment of the river in this watershed does not support some or all of its designated uses, based on biological and/or water-quality data. Pathogens contribute to the impairment of the segment. See tables for details.

Watershed rankings. The ranking formula provides a preliminary ranking by synthesizing a broad spectrum of watershed characteristics, current conditions, and threats. This watershed ranks in the group with the highest need for protection and/or restoration. This rating is for the watershed on average: particular sites and particular waters within the watershed may vary widely. See tables for details.

Volunteer data. There is a volunteer site on Twomile Creek. See tables for details.
