OVERVIEW

Geography. The Clear Creek watershed covers northwest Jessamine County and southern Woodford County. The land is in the inner subregion of the Bluegrass physiographic region, characterized by undulating terrain and moderate rates of both surface runoff and groundwater drainage. The watershed lies above thick layers of easily dissolved limestone that form carbonate aquifers. Groundwater flows through channels in the limestone, so caves and springs are common in regions with this geology.

Waterways. Clear Creek empties into the Kentucky River just below Lock and Dam Number 6. Among the creeks that feed it are Tanners Creek, Spring Creek, and East Fork Clear Creek.

Land and water use. Land in the watershed is mainly agricultural; almost 5% is rural and wooded, and 2% is residential. One business holds a permit for discharges into the creeks. See tables for details.

Agency data assessment. The assessed creek segments in this watershed include one designated as threatened, based on biological and/or water-quality data. 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 a moderate 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. Both volunteer monitoring sites on Clear Creek showed phosphorus levels elevated enough to cause potential nutrient enrichment problems (> 0.1 mg/L). One site also exhibited high levels of bacteria indicative of fecal contamination (above 200 colonies/ml). Thallium was also elevated at this site. See tables for details.
