Dayton approves partial financial support for Diamond Lake chemical treatment

The Dayton City Council agreed to provide some financial support to the fledgling Diamond Lake Association. Association President Chris Covington and Member At Large Mike Byrne made a presentation to the council in April seeking financial support to chemically treat Diamond Lake for curly-leaf pondweed. At that time the Association was waiting to hear back about receiving a DNR grant that requires matching funds. At that meeting, council wanted the Association to seek financial support from residents on the lake. They suggested they would consider pitching in for partial financial support but not 100 percent coverage.

Covington and Byrne returned to the May 14 meeting informing the council the Association had selected Clarke Aquatic Services, located in Clearwater Minnesota and signed a contract with them for treatment. Clarke conducted the pre-treatment survey the week of May 6. The pre-treatment survey showed 75 percent of Diamond Lake is impacted by curly-leaf pondweed.

Based on the findings from the pre-treatment survey, the curly-leaf pondweed invasive species treatment area covers the public access, the center part of the lake, and residential areas..  Aquathol K will be applied at .75ppm over 60.5 acres (60.5 acres is the maximum allowed without a variance from the DNR) at an average depth of 5.42 feet.  At $192.27 per acre at that depth and concentration, this works out to $11,632.34 plus sales tax. The total cost for the first treatment of the lake comes to $12,478.60.

The DNR approved the grant for 60.5 acres at $100 per acre, for a total of $6,050. However, a caveat to the grant is that it will not be paid out until after treatment is completed.  The Association must also come up with the difference of $6,428.60.

Covington said the Association has at least 20 homeowners willing to contribute if the city is willing to contribute 50 percent of the difference at a cost of $3,214.30.  This is based on a 20 household participation number of $161 per household. Covington reasoned the lake is an amenity for the entire city which is why the Association would like the city’s participation.

The Association also asked for a bridge loan from the city for the initial $6,050 to be reimbursed by the DNR grant.

Initially the council wanted to provide Attorney George Hoff with time to draw up a contract and bring it back at a future meeting. However, since the treatment must be done when the water is between 50 and 60 degrees and the water was reading at 57 degrees already, the council authorized Hoff to work with the Association over the coming days to reach an agreement that includes the city providing the initial funding of $12,478.60. The agreement would also have to stipulate the city would be reimbursed for all but $3,214.30. This means the council approved splitting the cost of the difference after the DNR grant funds are allocated to the project.

Several Diamond Lake Association residents in attendance applauded the council’s decision.

Since the meeting, Covington confirmed the Association supervised the chemical treatment of the portion of the lake as planned. This included the boat landing area out towards the middle as well as some areas near residential properties. He said they have secured payments from the residents who pledged to support the project and are now awaiting to hear from the city.
