The dam is an earthfill embankment with variable height and cross section. The average bottom width is about 90 feet and the top width is about 18 feet, with top elevation at 21.5 feet above mean sea level. The reservoir has a capacity of 26,500 acre-feet encompassing a surface area of 2,490 acres at the conservation pool elevation of 17.5 feet above mean sea level. Water level is maintained by pumping from the Rio Grande during off-season irrigation demands.
