Enclosed is a map of the areas that were treateted on Big Lake and Mitchell Lake.
I also talked to the DNR about all the fish we are finding dead on the lake shore. All indications are that the fish kill is being caused by a bacterial infection called Colmnaris.The way I understand this is that most fish carrier this but when the fish are stressed it is detrimental to their survival. The fish were stressed this year by the fast lake temperature increase when it got so hot. This was also during their spawning period when they are already under stress.

The following is a summary of the Lake Vegetation Management Plan that has been developed, submitted and approved for Lake Mitchell and Big Lake.

On December 21, 2010, the Minnesota Regional Fisheries signed this three year permit .

With a written consent by any and all shoreland owners, their entire lake side footage can be treated in the early spring for Curly-Leaf Pondweed and Eurasian Watermilfoil. This lifts the state's limit of only 15% of any lake's surface to be chemically treated.

Should there be a significant negative impact to the native aquatic plants or water quality, the Minnesota Department of Natural Resources will assist the Big Lake Community Lakes Association to find alternative treatment plans.

If any shoreland holder has concerns with nuisance submerged vegetation, the area will be inspected by the Department of Natural Resources. Additional treatment may be granted to not exceed 35 feet of shoreline, out 50 feet from shore plus a 15 foot wide channel to open water.

If the treatment of Curly-Leaf Pondweed and Eurasian Watermilfoil allows other aquatic plants to excessively grow and become recreational nuisances, the treatment area limitations will be revised.

This highlights the key points of our Lake Vegetative Management Plan that impact our lake system. Should you be interested in reading the document in its entirety, please contact the president of the lake association, Ken Warner.
