Note générale :	Four recharge tests were conducted by injecting water from playa lakes through wells into the Ogallala formation. Injection was by gravity flow and by pumping under pressure. At one site, 34-acre feet of water was injected by gravity and produced a signifiant increase in field of the well. At a second site, gravity injection of only 0.58 acre-feet caused a signifiant decrease in permeability due to plugging by pumping 6 and 14 acre-feet respective by resulted in discharge of water at the surface and in perching of water above the water table.
