Regional Watershed and Stormwater Management
Across Doña Ana and Sierra counties there are 2,400 square miles of watershed stretching from the Black Range northwest of the Caballo Dam, south to the NM-TX state line. For 800 square miles, or one-third of the area, there is no existing infrastructure to manage stormwater. This results in severe erosion, flooding, and large quantities of sediment and debris being dumped on residences, farm fields, highways, and streets during severe weather.
