Tularosa Valley Watershed Overview. 5 Tularosa Valley Watershed (HUC8 13050003) Overview The Tularosa Valley Watershed is located in southern-central New Mexico and in the northwestern part of Texas. It covers 4,292,993 total acres (17,373 sq. km). Portions of the Tularosa Valley Watershed are in Dona Ana, Lincoln, Otero, Sierra, Socorro, and Torrance counties in New Mexico and in El Paso and Hudspeth counties in Texas.

Tularosa Valley Watershed acreage distribution. Tularosa Valley Watershed (HUC8 13050003) Physical Setting Geology: The Tularosa Valley HUC has a northern boundary near Kerr Well near Gran Quivira. It is bounded on the west side by Chupadera Mesa, the Oscura Mountains, the San Andres Mountains, the Organ Mountains, and the Franklin Mountains. It is bounded on the east side by Atkinson flats, Gallinas Peak, Rough Mountain, Tecolote Peak, the Sacramento Mountains, the Vera Cruz Mountains, the Sacramento Mountains from Sierra Blanca to Culp Peak, Otero Mesa, and the Hueco Mountains. The Tularosa Valley is an enclosed basin with no external outlet and is part of the Rio Grande Rift. A playa called Lake Lucero is the remains of the Pleistocene Epoch Lake Otero remains. Lake Lucero playa is rich in gypsum and other salts. The San Andres Mountains, Chupadera Mesa, Oscura Mountains, Sacramento Mountains Otero Mesa, and the Hueco Mountains are composed of Pennsylvanian Period limestone at the crest, which changes to Permian Period limestones, sandstones, siltstones, anhydrite, gypsum, halite and dolomite until the valley floor is encountered. The limestone is porous. The Organ Mountains, Gallenas Peak, Rough Mountain, Tecolote Peak, Carrizo Mountain, Sierra Blanca, the Vera Cruz Mountains, and the Jarilla Mountains are Tertiary Period granite intrusions. Surrounding Sierra Blanca are middle Tertiary Period volcanics. Along the western mountains and especially the southern portion of the valley floor, Quaternary-Tertiary Period partly compacted sands and gravels of the Santa Fe group occur. The Santa Fe Group consists of alluvial fans, river channel deposits and inter-bedded volcanic rocks preserved in a complex of depressed fault blocks within the Rio Grande depression. Quaternary Period piedmont alluvial sediments form alluvial fans along the mountains. In the north the Corrizozo lava
