Geography. The Griers Creek watershed is in west-central 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. Griers Creek empties into the Kentucky River just above Tyrone. Its several branches drain the area south of downtown Versailles.

Land and water use. Land in the watershed is about 80% agricultural, more than 10% rural and wooded, and the remainder residential, commercial, or industrial. Four businesses and organizations hold permits for discharges into the creeks. See tables for details.

Agency data assessment. The assessed creek segment in this watershed only partially supports its designated uses, based on biological and/or water-quality data. A variety of factors contribute to the impairment of these streams. 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. Phosphorus levels in Griers Creek were elevated enough to cause potential nutrient enrichment problems (> 0.1 mg/L). A significant amount of the triazine herbicide atrazine was detected (>1 microgram per liter); however, the concentration of atrazine was below the EPAís maximum contaminant level of 3 micrograms per liter. See tables for details.
