Houston Public Works will lower Lake Houston by 6 inches on Monday, May 20th to allow contractors to begin a rehabilitation project on the dam. Lake Houston will be lowered another 6 inches on Tuesday, May 28th following Memorial Day weekend, for a total of 1 foot. Work on the dam will continue through the end of the year.
The levels in Lake Houston will naturally return to full and require lowering to 41.5 feet to continue the rehabilitation project. Property owners should be prepared, as advance notice may not be possible.
Separately, if Lake Houston is above 41.5 feet and the National Weather Service predicts greater than 3 inches of rain within a 48-hour period, the lake may be temporarily lowered to 41.5 feet before the storm. It takes 24-hours to lower Lake Houston by 12-inches. Lake Houston has a normal pool elevation of 42.5 feet.
