DEXTER, Iowa (AP) – Officials say a leaking pipe has caused wastewater to discharge near Diamondhead Lake in Guthrie County.

The state Department of Natural Resources says wastewater from a sanitary sewer line began bubbling up Friday morning from an underground pipe on the west side of Diamondhead Lake.

Officials believe the pipeline leak occurred after the installation of a power pole. Wastewater is discharging about 300 feet from the lake but has not reached the water.

The Diamondhead Lake Sanitary District expects the discharge to be ongoing until at least Saturday. Residents are being encouraged to avoid swimming and wading near the area.
