Rising pool levels – caused by Hurricane Harvey’s torrential rainfall – in Barker Reservoir and Addicks Reservoir are spilling over into adjacent subdivisions that sit against the dams. Officials warn that thousands of homes are at risk and have issued voluntary evacuations for at least 80 subdivisions.

By Monday night, at least 100 to 200 began homes flooding. Officials expect that homes will continue to be impact throughout the week. The map shows which subdivision are at risk.
