A day before Hurricane Harvey made landfall on the Texas coast last August, an internal U.S. Army Corps of Engineers forecast predicted that the storm would fill Houston's Barker Reservoir to record levels, flooding neighborhoods on the reservoir's western border for two weeks or more, government records show.

That projection was made Thursday, Aug. 24, 2017 - before Harvey hit Houston. The next day's Army Corps forecasts got worse and worse: Both Barker and Addicks reservoirs would spill beyond government-owned land, engulfing nearby homes and businesses.
