Of the City's lakes, nine of them (Baldwin, Centerville, George Watch, Marshan, Peltier, Reshanau, Rice, Sherman, and Ward) are located within or abutting the Chain of Lakes Regional Park. The City lakes generally fall into three shoreland management categories: Natural Environment, Recreational and General Development. The Natural Environment lakes are primarily located in the Chain of Lakes area and include Peltier, George Watch, Marshan, Rice, Ward, Sherman, Cedar, Amelia, Rondeau and Wilkinson. Recreational lakes include Otter, Centerville, Reshanau, and Baldwin. Bald Eagle Lake is a General Development Lake. They are used for a variety of recreational uses such as swimming, boating, fishing and water skiing. Centerville, Bald Eagle, Peltier and Reshanau Lakes are considered game fishing lakes. A metric used to evaluate lake water quality is the level of eutrophication, the enrichment of lakes due to excess nutrients such as phosphorus. Although phosphorus is the dominant factor, as both phosphorus and nitrogen concentrations increase in lake water, algae blooms increase. In the extreme, blue -green or scum - forming algae can render a lake unusable for recreation. The degree of eutrophication is characterized by gradations of oligotrophic and eutrophic levels. Oligotrophic lakes have very low nutrient levels, high City of Lino Lakes SWMP 1 February 8, 2013 Draft 1 24
