Water is expected to rise about 4 to 6 inches per hour in Buffalo Bayou, which cuts through downtown Houston, after the controlled release. Much of the area is already flooded from the heavy rain. All roads near the dams will be flooded “for an extended period of time,” and homes upstream of the reservoirs could be flooded for months, Col. Lars Zetterstrom, the Corps’ district commander, said Sunday.
According to KHOU, thousands of homes will likely be impacted by the release. Officials have urged residents in the area to leave their homes as part of a voluntary evacuation, but to only do so on Monday when there is daylight.
