Water Supply
 
Aquifers occur in the sandstone, limestone, and coal in the watershed. The groundwater is used as a domestic drinking water supply as well as for watering livestock and other farm activities. In hilltop and hillside areas, the aquifers are unconfined and commonly have insufficient yield. Valley areas have partly confined and confined aquifers. The range of depth typical for water wells in the watershed is 50-300 feet. Yields are usually 1-30 gallons per minute (gpm), but may exceed 200 gpm. The groundwater is hard to very hard, alkaline, and has large iron concentrations locally.
