Lake Minnewashta beach

Metropolitan Council Environmental Services responded to a sanitary sewer break in Chanhassen Thursday, June 20. 

City of Chanhassen staff alerted MCES to the wastewater spill Thursday evening and MCES transferred wastewater flow to an alternate sewer approximately 10 minutes later, stopping the spill according to a Met Council press release

The spill occurred along the south side of Highway 7 near Arbor Lane and near the north end of Lake Minnewashta.

Wastewater flowed along a bike path and through a local storm sewer into a stormwater holding pond north of the lake. Wastewater may have flowed from this pond into a channel that extends north from Lake Minnewashta between approximately Dartmouth Drive and Washta Bay Court.

As a precaution, MCES posted signs June 21 for no swimming or fishing in the channel between Dartmouth Drive and Washta Bay Court until further notice, according to a city of Chanhassen alert, issued Friday.

Additional crews collected water samples June 21 to see if the spill affected the lake and to what extent.

"Typically wastewater will adequately decompose in the water, and MCES does not anticipate any long-term effects from the wastewater spill," according to the Met Council press release.
