The Two Rivers Dam is a dry dam in southeastern New Mexico, sixteen miles west-southwest of the city of Roswell. The dam is actually two dams separated by an area of higher land approximately 1.5 miles wide. Normally, no water is impounded behind the dams; they are strictly for flood control. However, during the spring runoff water will back up behind the northern dam. This has created a small oasis in the lowlands behind the dam.
Both dams are earth-fill dams with coarse rubble on the faces to prevent erosion. The tops of both dams are 4058 feet above sea level. During a flood, each dam's reservoir is separate until the water reaches 4000 feet above sea level, at which point the two reservoirs combine to form a single large reservoir.
