In the limestone-rich area of Green County, more than three-quarters of the drilled wells in the 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 in the Green and Barren River Valleys, only a few wells yield enough water for a domestic supply. Springs with flows ranging from a few gallons per minute too 318 gallons per minute are found in the county. Minimum flow generally occurs in early fall, maximum flows in late winter. |
