Artificial-Recharge Tests in Upper Black Squirrel Creek Basin, Jimmy Camp Valley, and Fountain Valley, El Paso County, Colorado

Abstract: Nine artificial-recharge pits were excavated in the alluvium in upper Black Squirrel Creek basin, Jimmy Campy Valley, and in the alluvium overlying the Widefield aquifer in Fountain Valley. Each artificial-recharge site was instrumented to measure inflow, stage fluctuations, and water-table fluctuations. Artificial-recharge tests conducted in upper Black Squirrel Creek basin indicated that the average adjusted rates of infiltration for the three sites ranged from 1.6 to 2.4 feet (0.5 to 0.7 meter) per day. Tests conducted in Jimmy Camp Valley indicated that the average adjusted rates of infiltration for the two sites ranged from 3.8 to 24.7 feet (1.2 to 7.5 meters) per day. Tests conducted on the Widefield aquifer indicated that the average adjusted rates of infiltration for four sites ranged from 2.3 to 12.9 feet (0.7 to 3.9 meters) per day.
