"With Tropical Storm Harvey dumping record rainfall on Houston, the U.S. Army Corps of Engineers faced a dilemma as water volumes rose to perilous levels in its two reservoirs west of the city center.

The options: ordering controlled releases of water from the two dams, adding to flooding in already swamped neighborhoods; or holding tight and risk having water pour around or over the earthen dams, potentially rupturing them and causing far greater damage.

The Army Corps chose to let water out deliberately—at a rate of about 8,000 cubic feet per second, depending on how much rain continues to fall—through Buffalo Bayou, a river that cuts through downtown Houston. Even with the controlled release, Army Corps officials expect reservoir levels at the dams to rise throughout the week."
