GOODENOUGH SPRINGS. The Goodenough Springs, also called Hinojosa Springs, are now submerged by Amistad Reservoir on the Rio Grande west of Del Rio in Val Verde County (at 29°32' N, 101°15' W). Before 1968, when they were inundated by Amistad, they were the third largest group of springs in Texas, with an average annual flow of 3,900 liters per second. In the early 1900s the springs powered a waterwheel used to raise irrigation water to the top of the adjacent high bluff. The springs rise from limestone under artesian pressure but are now on the northeast side of the lake at a pointnormally beneath forty-six meters of water; this submergence has considerably reduced the springs' flow. In winter, when the springwater is warmer than the lake water, it rises to the surface and produces a smooth area. The springs' location is marked by a buoy.
