Houston, TX – Council Member Dave Martin would like to make Lake Houston Area residents aware that Houston Public Works is monitoring two tropical developments approaching the Gulf of Mexico labeled by the National Weather Service as Tropical Storms 13 and 14. If these storms develop, Houston Public Works is preparing for the potential release of possibly between 6 to 12 inches, which would lower the lake to 40.5 feet or 40 feet. Property owners should make arrangements now to secure boats and other items along the shoreline for a potential lowering of Lake Houston.

Current forecast models show potential landfall of the storms as early as Tuesday, however, forecasts can change quickly and residents should be prepared in the event Lake Houston needs to be lowered this weekend. Both lakes within the San Jacinto Watershed are approximately one foot lower than their conservation pool, which means immediate lowering is not necessary based on existing forecasts.

Lake Conroe’s current elevation 199.8 mean sea level (msl) with a conservation pool elevation is 201 msl. There is currently 22,672 acre-feet of storage available on Lake Conroe.  There are approximately 445 square miles of land draining to Lake Conroe. Lake Houston’s elevation is 41.75 msl with a conservation pool elevation of 42.4 msl. 

In the meantime, Houston Public Works, Houston Police Department, and the Houston Fire Department are making preparations to put in place high water vehicles as well as barriers near locations known to flood. All agencies are monitoring the weather closely and actively communicating on pre-storm procedures. Residents can help us prepare for this storm by making sure that all drains are clear, keeping our storm water lines free of debris.

FOR IMMEDIATE RELEASE
Date: 05/17/2019
HOUSTON –  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. To monitor current water levels at Lake Houston, visit:
www.coastalwaterauthority.org

Property owners should secure property along the shoreline.

For more information on the Lake Houston dam rehabilitation
project, contact Erin Jones.
