Lake Houston will be lowered for work on the dam.

Houston Public Works lowered Lake Houston by 6 inches on Monday, May 20, to allow contractors to begin a rehabilitation project on the dam. Lake Houston will be lowered another 6 inches on Tuesday, May 28 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. To monitor current water levels at Lake Houston, visit

Property owners should secure property along the shoreline.
