A dam on an eastern Iowa lake suffered a “catastrophic” failure Saturday, sending a massive amount of water into nearby communities and forcing residents to flee, officials said.
The Lake Delhi dam, about 45 miles north of Cedar Rapids, failed as a result of “massive rain — a very unusually high amount this season,” according to Jim Flansburg, communications director for Gov. Chet Culver.
Culver told CNN that nearly 10 inches of rain had recently fallen in a 12-hour period in the area and was “too much water for the dam to hold.”
The roads on either side of the dam — which were part of the dam’s containment measures — apparently gave out as a result of the rainfall, Flansburg told CNN.
The National Weather Service reported a 30-foot-wide gap in the berm alongside the dam.
