DEXTER, Iowa (AP) — About 1,000 gallons of untreated wastewater discharged near a lake in Guthrie County, according to state officials. The state Department of Natural Resources said a power loss on Sunday afternoon caused a sewer pump to fail on the west side of Diamondhead Lake near Dexter.

About 1,000 gallons of untreated wastewater discharged from a manhole, but it is unclear how much of it reached the lake. Officials restored electricity and repaired the pump. The DNR said it will continue to monitor the situation.
