The headwaters of the Pecos River are located north of Pecos, New Mexico, United States, at an elevation of over 12,000 feet on the western slope of the Sangre de Cristo mountain range in Mora County[1]. The river flows for 926 miles through the eastern portion of that state and neighboring Texas before it empties into the Rio Grande near Del Rio. The river's drainage basin is approximately 44,300 square miles (114,736 km2) in size.[2]

ModificationsEdit

There are multiple dams along the Pecos River. Santa Rosa Lake is 117 miles/188 kM east of Albuquerque. Sumner Lake is located between Santa Rosa and Fort Sumner, NM. Two dams are located north of Carlsbad, New Mexico, at Avalon Reservoir and Lake McMillan, to help irrigate about 25,000 acres (10,117 ha) as part of the Carlsbad reclamation project (established in 1906). Texas has also dammed the river at the Red Bluff Dam in the western part of that state to form the Red Bluff Reservoir. The portion of the reservoir that extends into New Mexico forms the lowest point in that state.

HistoryEdit

The river played a large role in the exploration of Texas by the Spanish. In the latter half of the 19th century, "West of the Pecos" was a reference to the rugged frontiers of the Wild West.

New Mexico and Texas disputed water rights to the river until the federal government settled the dispute in 1949 with the Pecos River Compact. The Pecos River Settlement Agreement was signed between New Mexico and Texas in 2003.

Wild and Scenic RiverEdit

On June 6, 1990, 20.5 miles (33 km) of the Pecos River—from its headwaters to the townsite of Tererro—received National Wild and Scenic River designation. It includes 13.5 miles (22 km) designated "wild" and 7 miles (11 km) designated "recreational."[3]

Pecos River FlumeEdit

The Flume is a modern aqueduct carrying irrigation water over the Pecos River. Construction took place from 1889 to 1890 and was part of the Pecos River Reclamation Project. It was originally constructed of wood and spanned 145ft. It carried water at a depth of 8 feet. In 1902, a flood destroyed the Flume and it was subsequently rebuilt using concrete. In 1902, it was the largest concrete structure in the world.

The Flume and its surrounding area have been reclaimed by the city of Carlsbad and has been transformed into a tourist attraction with park improvements along the river and spot lights to give a spectacular nightly view.
