Metropolitan Council Environmental Services is Responding to a Wastewater Spill in the City of Chanhassen

Metropolitan Council Environmental Services is Responding to a Wastewater Spill in the City of Chanhassen Metropolitan Council Environmental Services (MCES), operator of the metro-area wastewater collection and treatment system, is responding to a wastewater spill from an apparent break in one of its regional force main sanitary sewers that occurred on Thursday, June 20, in the City of Chanhassen.

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.

MCES staff are collecting water samples today (June 21) to see if the spill affected the lake and to what extent. As a precaution, MCES posted signs alerting the public to the wastewater spill and encouraging people to temporarily avoid the posted area at the channel and stormwater pond. Typically wastewater will adequately decompose in the water, and MCES does not anticipate any long-term effects from the wastewater spill.

City of Chanhassen staff alerted MCES to the wastewater spill Thursday evening. MCES transferred wastewater flow to an alternate sewer approximately 10 minutes later, which stopped the spill. MCES is working to determine the volume of the spill. MCES has an emergency contractor repairing the damaged sewer today (June 21).

For more information, please contact Tim O’Donnell, Senior Information Coordinator at MCES, at or 651-602-1269.

Damage to the Water Ski Course – Please Use Caution

Did you know that Lake Minnewashta is home to a number of enthusiastic water skiers? We are lucky to have our very own ski course set up in the north bay of the lake, permitted by the Sheriff and maintained by some of our residents.

Sometime between June 8th and June 11th, one of the ski course structures was notably damaged and rendered unusable until repairs are made. The cost of replacement parts is at least $150 plus a couple hours of work to pull everything out, replace the broken pieces, and reset everything.  Plus a lot of sad skiers, sitting on their docks waiting for repairs. 🙁

Are you curious as to how a ski course works? The two yellow balls are set up for a tow boat to drive between, The red/orange balls are turn buoys for a skier being towed to turn around. A series of ropes, plastic pipe and anchors hold the turn buoy a set distance away from the boat. Skiers compete by seeing who can make the most turns without missing a buoy as the ropes are shortened with each successive run.

More than likely the damage was accidental, possibly caused by a boater dragging a line or anchor rope through the course, snagging the underwater structure and snapping it.

To avoid future damage, please do not drive between the yellow and orange buoys. Better yet, if you are not skiing the course, please avoid it at all times.

Our lake elevation readings on Lake Minnewashta have been below 945.0′ Mean Sea Level for 3 days in a row. Based on this, Renae Clark, city of Chanhassen Water Resources Coordinator, after discussion with city manager Todd Gerhardt, has confirmed the Slow No Wake restriction has been lifted.

The City’s Surface Water Quality hotline is being updated to reflect this and the signs at the Lake Minnewashta Regional Park boat launch are being removed. A resolution at the Chanhassen City Council meeting will be presented tonight to essentially codify the elevation of 945.0′ MSL as the trigger for placing and removing any future Slow No Wake declarations on Lake Minnewashta.

Thanks everyone for your help, cooperation and understanding. Thanks especially to Rick Zweig for posting the readings everyday.

Minnesota legislators doubled what boat owners must pay to help protect state waters against invasive species

Looks like the State will be getting more money to spend on AIS efforts. They’re raising the boat registration fee by $5.60! Hopefully the LMPA or Carver County get grant money in 2020. Unfortunately the move to centralize AIS inspections for more lakes in Wright County was denied. 

From a recent Star Tribune Article

“To strengthen the DNR’s fight against zebra mussels, starry stonewort algae and other aquatic invasive species (AIS), the House and Senate raised the AIS boat licensing surcharge from $5 to $10.60.”

“Strommen said the funding boost will extend the DNR’s lakeside inspection program, reinstate local grants to AIS partners and fortify the Minnesota Aquatic Invasive Species Research Center. Also to the DNR’s liking, an attempt by certain legislators to expand a controversial AIS inspection program in Wright County failed.”

Here’s a link to the entire article.
