Recent storms packed the mountains of southern Colorado and northern New Mexico with healthy snow levels, and meteorologists anticipate El Niño conditions will persist through the spring. This is welcome news after last year’s dry conditions. But in the long term, forecasters and farmers still remain cautious. That’s because long-term drought has dried out the state’s soils. And reservoirs remain low, particularly on the Rio Grande and its tributary, the Chama River.
On the downstream side of Elephant Butte Dam, U.S. Bureau of Reclamation employees navigate a stairwell above the Rio Grande, passing scat from the ring-tailed cats that like to hang out here, and enter through a door into the 300-foot tall concrete dam. Built in the early twentieth century, Elephant Butte Dam holds back water stored for farmers in southern New Mexico, the state of Texas and Mexico. At full capacity, the reservoir is about 40 miles long and can retain more than 2,000,000 acre feet of water. Jesse Higgins, an electrician who manages the powerplant at the dam, goes first and flips on the lights, which flicker and fire up after a few minutes. Labyrinthine tunnels burrow throughout, and water drains along the sides of the narrow, elevated path.
Right now, New Mexico’s largest reservoir is at about three percent capacity, with just 62,573 acre feet of water in storage as of September 20. Elephant Butte Reservoir’s low levels offer a glimpse of the past, as well as insight into the future. Over the past few decades, southwestern states like New Mexico have on average experienced warmer temperatures, earlier springs and less snowpack in the mountains. And it’s a trend that’s predicted to continue. “There was no spring runoff this year.
