| 摘要： | Officials with the Vicksburg Engineer District's Thatcher Lock & Darn, the northernmost navigation structure on the Ouachita River in Arkansas, first noticed something wrong at the structure in late October 2021. What's transpired since then has been a testament to the ingenuity of the Vicksburg Districts engineering and maintenance team and a good example of community partnership.Thatcher Lock & Dam features a 200-foot-long hinged crest gate that stretches across the Ouachita River. The gate is about 5 feet high and, in normal conditions, has about a 1-foot head over the top. The gate is designed to maintain an elevation of 77 feet on the Ouachita. In high-water conditions, the level above and below the structure can equalize, at which point Corps officials can lower the hinged gate, allowing vessels to pass without going through the lock chamber. |
