About the Refuge

Sunset over Bitter Lake National Wildlife Refuge's wetlands/USFWS

Straddling the Pecos River, Bitter Lake National Wildlife is a wetland oasis inhabited by a diversity of wildlife.


The refuge protects and provides habitat for some of New Mexico's most rare and unusual creatures such as the least shrew, Noel's amphipod, least tern, Pecos sunflower, and Roswell spring snail.

Located where the Chihuahuan Desert meets the Southern Plains, Bitter Lake National Wildlife Refuge is one of the more biologically significant wetland areas of the Pecos River watershed system.  Established in 1937 to provide wintering habitat for migratory birds, the refuge plays a crucial role in the conservation of wetlands in the desert Southwest.
