In the southern half of Logan 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 day have been reported from wells penetrating large solution channels. In the low-lying areas of the Red River and its main tributaries, most wells are inadequate for domestic use, unless the well intercepts a major solution opening in the limestone, and then the yield may be very large. Groundwater is not as prevalent in the northern half of the county as it is in the southern half of the county. Only a few wells in the northern half of the county yield enough water for a domestic supply. Springs with flows ranging from a few gallons per minute to 2,636 gallons per day are found in the county. Minimum flows generally occur in early fall, maximum flows in late winter. |
