Elephant Butte Reservoir is located about 125 miles north of El Paso, Texas on the Rio Grande. The reservoir is approximately 35 miles long with a narrow neck, called the Narrows, about 15 miles upstream from the dam. Historically this reach of Rio Grande where the reservoir is located has been aggrading before the reservoir was built. High inflows have increased the aggradation rate at the upper end of the reservoir. The increased rate of river bed aggradation has resulted in a delta formation and has created a complex sediment management and water delivery problem to the reservoir. The reach of the reservoir modelled in this study extends from the upper end of the reservoir to the Narrows. The HEC-6T model (Thomas, 1994) was used for this simulation.
