Overview | ||
In this highly karstic, limestone-rich county, most of the drilled wells in the southern half of the county are adequate for a domestic supply. Yields as high as 50 gallons per minute have been reported from wells penetrating large solution channels, with adequate wells producing as deep as 500 feet. In the uplands of the northern half of the county, less than half the drilled wells yield enough water for a domestic supply. In low-lying areas of the Nolin River, Bear Creek, and Dog Creek and their main tributaries, most wells are inadequate for domestic use, with the exception of a few wells that yield enough for a domestic supply from depths of 150 feet or more. Springs with flows ranging from a few gallons per minute to 50,000 gallons per minute are found in the county. Minimum flows generally occur in early fall, maximum flows in late winter. |
