How We Calculate These Numbers

Daily history for Elephant Butte Reservoir uses the Bureau of Reclamation's daily elevation values from RISE.

The same-day mean at Elephant Butte Reservoir uses 11 readings on this calendar day from 2015 through 2025 and equals 4,306.10 ft. All of these figures come from station 332. Percent full is shown only when an agency published it; it is never estimated by dividing elevation by a pool elevation.
