Lake Lowering to Begin at Noon – Sunday, September 12

Mayor Pro TemDave Martin would like to make Lake Houston Area residents aware that Lake Houston will be lowered down to 41.5 feet beginning at Noon tomorrow, Sunday, September 12. Houston Public Works, Coastal Water Authority, and San Jacinto River Authority are working together closely and monitoring the tropical system approaching the Gulf of Mexico this weekend and early next week.

Property owners should make arrangements now to secure boats and other items along the shoreline of Lake Houston. Lowering will start at Noon tomorrow and it only takes 24 hours to lower Lake Houston one foot.

National Weather Service Houston-Galveston is now forecasting 3+ inches of rain for our watershed on Monday evening. Houston Public Works will adhere to our standard lake lowering procedure which is to lower Lake Houston by one foot to 41.5 ft. when three inches of rainfall is predicted for our region. Should the forecasted rainfall amounts exceed 6 inches of rainfall in our area, additional lowering may be conducted at that time.

Lake Houston is currently at 42.29 ft, normal pool is 42.4 ft. Lake Houston lake levels may be monitored by visiting www.coastalwaterauthority.org. Lake Conroe is currently 199.74 ft, which is just over one foot lower than their normal pool of 201 ft. Lake Conroe lake levels can be monitored by visiting www.sjra.net.
