Elephant Butte Dam or Elephant Butte Dike, originally Engle Dam,[2] is a concrete gravity dam on the Rio Grande near Truth or Consequences, New Mexico, in the United States. The dam impounds Elephant Butte Reservoir, which is used mainly for agriculture but also provides for recreation, hydroelectricity, and flood and sediment control. The construction of the dam has reduced the flow of the Rio Grande to a small stream for most of the year, with water being released only during the summer irrigation season or during times of exceptionally heavy snow melt.
