Construction


Until recently only 21 of the District's 23 dams were classified as high hazard. In February 2016 Texas Commission on Environmental Quality (TCEQ) re-classified the two remaining low hazard dams to a high hazard classification. As of April 2016, 19 of the 23 dams have been upgraded in accordance with TCEQ regulations. Construction will begin on the Dam No. 7 Modernization Project in June 2016. Design is underway for Dam No. 8 Modernization, with construction expected to begin in late 2017. Dams No. 10A and No. 10B (recently reclassified) will be evaluated for modernization in the near future.

The U.S. Geological Survey (USGS) has installed rainfall and reservoir level gages at 22 District dams, as well as four new stream gages on Brushy Creek and one on Lake Creek. Real time precipitation, reservoir elevation, and stream stage information is available on the District's Flood Monitoring System, and can be accessed by viewing the Flood Monitoring System page. The current and archived information is also available on the U.S. Geological Survey (USGS) website, and can be accessed by viewing the USGS webpage.
