Residents Flee as Rising Floodwater Eats 30-Foot-Wide Hole in the Earthen Dam
The Lake Delhi dam in eastern Iowa failed Saturday as rising floodwater from the Maquoketa River ate a 30-foot-wide hole in the earthen dam, causing water to drop 45 feet to the river below and threatening the small town of Hopkinton.
Northeast Iowa has been inundated with torrential rain in recent days with as much as 9 inches being reported in some locations. The heavy rain has pushed the Maquoketa River to 23.92 feet - more than 2 feet above its previous record of 21.66 feet in 2004.
Jack Klaus, a spokesman with the Delaware County emergency management office, said warning sirens were sounding in Hopkinton as water began to surround homes there Saturday afternoon. Areas below and above the dam had been evacuated, including numerous cabins and homes - as many as 700 - above the dam because of high water.
"There's going to be significant losses of property there," Klaus said.
