The dam surrounding the reservoir at the Lewis Creek Power Station near Willis continues to hold with no seepage or breaches. Workers are continuing to make repairs to areas where persistent heavy rains have caused the dam's soil to become saturated to the point of sloughing off.

According to San Jacinto River Authority, the issues concerning Entergy's dam will have no impact on the Lake Conroe Dam. Montgomery County, however, will be sending first responders to give notifications to specific neighborhoods that fall within an area of concern (click here for map) related to the ongoing repair work to the Entergy Lewis Creek Dam. Those neighborhoods are: Pelican Bay, Lakeside Place, Point Aquarius, Lake Conroe Hills, Walnut Cove, Lake Conroe Bay, Shadow Bay, Country Run, Enchanted Waters, and Bishop's Landing.

Entergy Texas, Inc. officials note that a dam failure remains only a possibility. But the company has committed to take every possible step to prevent failure. Additional workers have been brought in to make repairs.

Continued rainfall is the greatest threat to completing repairs. To address the potential for rainfall this weekend and into next week, more than eight acres of protective covering is being installed to shield affected areas of the dam. Steps are also underway with the addition of berms, including one of crushed concrete and lime which, when added to the toe of the levee, will stabilize the soils and prevent further slides.

The reservoir level continues to be lowered to ease pressure on the dam and it is being monitored by geotechnical engineers who are on site around the clock.

At this time, Entergy is reducing the water level of the lake to reduce the stress being applied to the dam. Entergy repair crews are also taking measures to prevent further dam deterioration. Emergency Management, Law Enforcement, Fire, and EMS met with Entergy officials this morning to discuss planning and response efforts that may be necessary pending any further deterioration of the dam.
