Houston officials closely monitor Lake Houston water levels as dam rehab project proceeds
Property owners near Lake Houston will deal with varying water levels through fall 2020 as the city completes the $10 million Lake Houston Spillway Dam Rehabilitation Project.
The water levels were lowered by 6 inches on Monday to allow contractors to start on the rehabilitation project and will be lowered another 6 inches on May 28.
It is important that water levels will be lowered to 41.5 feet throughout the entirety of the project, Houston City Councilmember Dave Martin said in a statement. If at any time the waters levels are to rise above 41.5 feet, it will be immediately lowered back, he noted.
The project is expected to be completed by fall 2020. The estimated construction cost of $10 million is being funded completely by the Coastal Water Authority’s Special Equity funds, which includes monies designated specifically for Houston infrastructure improvements. No funds from Houston’s coffers will be used on the project, city officials said.

The Coastal Water Authority is a conservation and reclamation district created by the state legislature to manage water resources for the City of Houston, such as Lake Houston.
The Lake Houston Spillway Dam Rehabilitation Project will provide increased stability to the dam through the installation of a new reinforced concrete training wall, according to Martin’s office.
This project also includes partial demolition of a splitter wall, which is the device used to break up the flow of water over the spillway. Contractors with Thalle Construction Company will build new concrete anchor blocks at the bottom of the training wall and elevate the Ogee and Stilling pool weirs by 7 feet, thus altering the water flow from the spillway.
