In the southern half of the county, more than three-quarters of the drilled wells in uplands are adequate for a domestic supply. Yields as high as 50 gallons per minute have been reported from wells penetrating large solution channels. In the low-lying areas of the West Fork of the Red River, and the Little River and its major tributaries, most wells are inadequate for domestic use, unless the well intercepts a major solution opening in the limestone, in which case the yield could be very large. Groundwater in the northern half of the county is not as prevalent as in the southern half, except in the area west of U.S. 41 between Hopkinsville and Crofton. Most drilled wells in the west-central section of the county that obtain water from fault zones are adequate for a domestic supply, and sometimes yield up to 100 gallons per minute. Most wells in the rest of the northern half of the county are inadequate for a domestic supply. Some wells in sandstone formations yield enough water for a domestic supply. Springs with flows ranging from a few gallons per minute to 3,000 gallons per minute are found in the county. Minimum flow generally occurs in early fall, maximum flows in late winter. |
