Elephant Butte: The Dam That Made the Desert Bloom
Near Truth Or Consequences, New Mexico
The butte out in the water does look like an elephant, or did before the reservoir swallowed its base. That basalt outcrop gave its name to the largest dam project the Bureau of Reclamation had ever attempted when construction began in nineteen eleven. Engineers plugged the Rio Grande here, building a concrete gravity dam that stood about three hundred one feet tall.
When it was finished in nineteen sixteen, Elephant Butte Reservoir was the largest reservoir in the world, holding more than two million acre-feet of Rio Grande water. It was also the first American dam requiring an international treaty, because its storage directly affected Mexico's water rights downstream. A small town called Elephant Butte sprang up to house construction workers and got its own post office in nineteen nineteen.
The workers left, but the lake stayed, eventually becoming New Mexico's largest body of water and the centerpiece of a state park that draws boaters and anglers from across the Southwest.
