Historical Data

Why does the lake level fluctuate? The reservoir is a man-made pool created to store water and prevent flooding. It is normal for water levels at Amistad Reservoir to fluctuate due to increased rainfall or ongoing drought and greater demand for water from the Rio Grande.

From 1992-2002, the reservoir dropped and remained low during an extended drought. A tropical storm system in 2003-2004 brought increased rain to southwest Texas. By 2005, the lake was near the conservation pool level of 1117 feet above mean sea level.

The reservoir maintained near conservation pool levels into 2011, before beginning to decrease. Historic low lake levels were reached in 2013 due to the most recent period of drought. The International Boundary and Water Commission continues to release water from Amistad Dam to provide for municipal use and irrigation for both US and Mexican communities downstream along the Rio Grande.
Boat Ramp Status

Many boat ramps at Lake Amistad were closed as a result of the historic low lake levels in 2013. Now that the lake levels are rising, the National Park Service is opening boat ramps as lake levels allow and it is safe to launch a boat from the ramp.

The Southwinds Marina boat ramp was the first ramp that we have been able to re-open as a result of the rising lake level. We will post the status of the boat ramps on this page so visitors can find out which boat ramps are open and available for use.

The lake reached its lowest point on May 23, 2013, at a level of 1055.93 feet above mean sea level, which was 61.07 feet below the reservoir's conservation pool level of 1117 feet. One year later on May 23, 2014, the lake is at 1070.79 feet above mean sea level; up 14.86 feet from the historic low.
