SPIRIT LAKE – A blockage in a sewer main caused an estimated 4,000 gallons of wastewater to overflow into Big Spirit Lake late Sunday morning.
The blockage caused wastewater to backup into at least one home and out of a manhole located at 13881 Center Drive prior to the Iowa Great Lakes Sanitary District getting the overflow stopped by noon. The city of Spirit Lake Water Department was notified of the bypass. Strong south winds on Sunday helped direct the overflow away from the beach and water intake.
As a precaution, the Ainsworth-Orleans beach owned by the Dickinson County Conservation Board, will post a swimming advisory.
