Red Bluff Reservoir is a reservoir on the Pecos River 40 miles (64 km) north of Pecos, Texas. The reservoir extends into Loving and Reeves Counties in Texas, and Eddy County in New Mexico. The northern shoreline of the reservoir is the lowest point in the state of New Mexico. The reservoir was formed in 1936 by the construction of a dam by the Red Bluff Water Control District to provide water for irrigation and hydroelectric power.
