Elephant Butte Reservoir

Prolonged drought in the southwestern United States has affected many water bodies, such as Elephant Butte Reservoir along the Rio Grande River, north of Truth or Consequences, New Mexico. The hydroelectric reservoir has had declining water levels over the past 20 years, as indicated in these Landsat images.

In 2009, the Bureau of Reclamation established a plan to implement conservation measures to restore water levels in the reservoir.

Landsat images are useful in monitoring water bodies for change over time and provide decision makers a visual effect of the declining water levels.
