The gray redhorse is also found in the Brazos and Rio Grande drainages of Texas, western tributaries of the Rio Grande below the Big Bend region in Mexico, and south on the Atlantic slope in the Rio Sota da Marina drainage, Tamaulipas. The gray redhorse formerly occured in the Rio Grande downstream from Elephant Butte Reservoir, the Pecos River downstream from Roswell, and the Black River. Adults most often occupy medium to large pools, with cobble, gravel, silt, or sand bottoms.
