Lake Houston Level Now Being Lowered in Advance of Hurricane Laura

Mayor Pro Tem Dave Martin announced at 4:31 p.m. Tuesday that Houston Public Works will initiate the temporary lowering of Lake Houston within the hour. The City made this decision after taking into account the fast-changing nature of Hurricane Laura. The Coastal Water Authority will lower Lake Houston to 41.0 ft from 41.59, another six tenths of a foot, which is 18 inches below full pool.

Laura should arrive late tomorrow or early Thursday as a Category 3 storm. Hurricane conditions are expected in Chambers and Liberty County – with 45-60 mph winds east of I-45 throughout the Lake Houston Area.

2 to 4 Inches Expected

The National Hurricane Center predicts that Hurricane Laura will bring 2 – 4 inches of rain to the Lake Houston Area in the next few days. Isolated areas could receive 6 inches. These rainfall amounts exceed the 3 inch trigger to lower Lake Houston, said Martin. 

Lake to Be Lowered Another 7.2 inches

As a result of these predicted rainfall amounts in addition to the rainfall that will be accumulated to our east, the Lake will be lowered gradually overnight from the current level, which is 41.6 ft down to an elevation of 41.0 ft. Six tenths of a foot is 7.2 inches.

The Lake will be maintained at a level of approximately 41.0 ft while there is an immediate inclement weather threat. Once that weather has moved out of our area, the Lake will be allowed to naturally refill from the storm’s runoff.

Some fluctuations in Lake level can be attributed to high winds so please keep that in mind when checking Lake levels.

Secure Shoreline Property NOW If You Have Not Already

Property owners were given notice Friday afternoon to secure property along the shoreline for a potential temporary lowering of Lake Houston. If you have not already done so now is the time to take action to secure your shoreline property.

The lake will be lowered at a cautious rate so as to not impact those living downstream. At the completion of this temporary lowering effort the total reduction in the level of Lake Houston from normal pool of 42.5 ft to 41.0 ft will be 1.5 feet. 

For More Information

Residents may monitor the lowering of Lake Houston by visiting the Coastal Water Authority website or visiting Mayor Pro Tem Martin’s Facebook page for updates from the District E office.

No Mention of SJRA

Martin’s press release made no mention of the SJRA or Lake Conroe. Lake Conroe, which is farther west should receive less rain than Lake Houston from Laura.
