Elephant Butte Lake: 8.7% full as of 2022-11-27

Elephant Butte Lake (located in New Mexico) is governed by the Rio Grande Compact. The Rio Grande Compact is an interstate compact signed in 1938 between the states of Colorado, New Mexico and Texas and approved by the U.S. Congress, to equitably apportion the waters of the Rio Grande Basin. Water from the lake supplies irrigation water as well as a portion of El Paso's supply when available.
