Recent rains have given Lake Amistad a significant boost, raising the reservoir by more than 3 feet in a week.
The lake’s average water level climbed from 1,056.42 feet above sea level Sept. 28 to 1,059.55 feet Oct. 5, according to the Texas Water Development Board.
The latest available reading Monday morning placed the lake slightly higher, at 1,059.57 feet, still approximately 57.4 feet below its conservation pool elevation of 1,117 feet.
According to the board, Texas’ share of Amistad’s conservation storage was 43.5% full Monday, up from 40% a week earlier.
The board listed reservoir storage at approximately 839,705 acre-feet, an increase of about 67,500 acre-feet since Sept. 28.
The gains are even greater over the past three months.
On July 5, the lake’s average elevation was 1,047.89 feet, reservoir storage stood at 614,113 acre-feet and Texas’ share of conservation storage was 29.7% full.
Since then, the lake has risen approximately 11.7 feet and added about 225,600 acre-feet of reservoir storage, while Texas’ share of conservation storage has increased by 13.8 percentage points.
Despite the recent gains, Amistad remains well below its conservation pool elevation.
The figures are provisional and subject to revision as additional measurements become available.
