The lake existed as a wetland until the late 1960's and early 1970's. After this time the wetland was dredged and took on the function of a shallow lake. In recent years residents have experienced a decline in lake water quality. Efforts have been made in the past to initiate rehabilitation of the lake. Please see Attachment 1, Reshenau Lake Management Plan, (Curley -leaf Pondweed Management) dated 4/8/2005 for a more comprehensive history of lake property owners efforts, and memo from Mathew Kocian from the Rice Creek Watershed District. Matt will attend the meeting on July 31st, to discuss vegetation management and other lake management issues concerning Reshanau Lake. Request Most of the effort at this time is centered around Curley Leaf Pondweed management. See item VII of Attachment 1. Other management issues identified are rough fish management, native plant restoration and shoreline restoration. A projected budget for 2009 is around $40,000. If the City were to partner in the effort to dean up Reshanau Lake, our cost would be 1 /3rd of the $40,000 or approximately $13,000. City Staff are proposing to use Surface Water Management monies for this purpose. Recommendations 1. Recommend the City form a partnership with the Rice Creek Watershed District and the Lake owners of Reshanau Lake to manage Reshanau Lake for better water quality, and to use Surface Water Management dollars for the City match 2. Other recommendations as per the Lino Lakes Environmental Board. 1. Reshenau Lake Management Plan, (Curley -leaf Pondweed Management) 2. Memorandum from Mathew Kociam, RCWD, 7/1/2008
