U.S. Army Corps of Engineers, Fort Worth District Officials, in keeping with their flood risk reduction charter, continue to monitor and manage recent flooding at Sam Rayburn Reservoir in Texas.

Sam Rayburn is receiving floodwater runoff from recent storms and is currently operating in surcharge pool with an elevation of 175.33 feet as of 8 a.m. June 2.  Conservation pool elevation is 164.40 feet and top of flood pool is 173 feet. Engagement of the labyrinth spillway is at 176 feet.

Operating according to the lake’s water control plan, Flood gates have been opened to total of six feet, releasing approximately 3,100 cubic feet per second.  Hydropower releases out of Sam Rayburn continue at 24 hours per day, releasing approximately 8,400 cubic feet per second. Additional Flood gate releases, in addition to the releases from power generation could be made over the next week or more.  All releases from Sam Rayburn Reservoir will continue to be passed to the Lower Neches River by B.A. Steinhagen/Town Bluff Dam. 

Public safety is the number one priority for USACE and we urge all visitors during high water events who are on or near the water to wear life jackets and use caution while navigating. Floodwaters have created unfamiliar boating conditions, changed shorelines, decreased height to overhead powerlines lines across the water, and has submerged objects such as picnic tables, signs, and debris.

Multiple campgrounds, boat ramps and day use areas have been closed due to flood waters. For additional information on facility closures visit,, or call the Sam Rayburn Project Office at 409-384-5716.
