The USACE Galveston District will close the Addicks and Barker reservoirs for varying periods to obtain a specific non-flooding pool elevation to take flow measurements through the new outlet structures. A new outlet structure at Barker Dam was put into operation on February 14, 2020, and a new outlet structure at Addicks Dam on March, 24, 2020. The closures will allow the Galveston District to take field measurements that will be used to validate and calibrate the outflows from the dam’s new outlet structures. The tests will ensure the dams are in compliance with USACE policy for the operation of both dams.
