Recommendations to evacuate are anticipated for Houston area residents near the Addicks and Barker reservoirs. In a no-win situation, officials are planning to open the reservoirs on Monday morning, to prevent catastrophic flooding in the area. Unfortunately, this will trigger an additional 4″ to 6″ per hour of water into Buffalo Bayou.
Army Cops of Engineers, Col. Lars Zetterstrom, said the Addicks Reservoir will be released around 2:00 AM, followed by the Barker Reservoir at 11:00 AM. Nearby homes would begin to be inundated around 2:00 PM.
“This flood event will exceed the 2016 tax day flood elevations,” Zetterstrom told Click 2 Houston. “Structures will be impacted upstream from both locations; the number of structures affected will depend on weather conditions.”
Zetterstrom explained that, while the dams are functioning, they must be released to avoid catastrophic flooding in the area. Engineers and officials from Houston City, Harris County, and Fort Bend County are coordinating to identify areas that will need to be evacuated.
Emptying the reservoirs will take around three months. The released water will travel around the dam, over a spillway, and affect the northern end of the Addicks Reservoir and both ends of the Barker Reservoir.
