INVENTORY <br />Lake Forest is a 3.6 acre lake located in Section 30, T. 30 N., <br />R. 23 W., in the southwest quadrant of I-694 and Silver Lake Road <br />in New Brighton. <br />On August 26, 1976, a field investigation was made to determine <br />the nature and extent of the problems associated with the lake. The <br />following summarizes the investigation: <br />LAKE CHARACTERISTICS: <br />A. 3.6 acres is the approximate surface area. <br />B. The water appeared brown in color from a distance. Exami- <br />nation of a water sample revealed the presence of algae, <br />.most of it nonfilamentous. There were no emergent species <br />of vegetation present along the shoreline.The water is <br />periodically treated with copper sulfate to control the <br />growth of algae. Vegetation along the shoreline is mowed <br />to present a neat appearance of the shoreline. <br />C. Waterfowl were utilizing the lake at the time of investi- <br />gation. Mr. Wozniak noted that otter and muskrat are <br />occassionally seen using the.lake, also. <br />D. The natural outlet is to the north (refer to map). The <br />normal level of water in the lake is considerably lower <br />than this outlet. Under present watershed characteristics <br />- it is doubtful that this outlet is used except during the <br />most severe storms. If the lake ever overflowed the <br />-water would flow into Pike Lake. <br />E. The sources of water for the lake are direct rainfall, <br />direct runoff from the slopes surrounding the lake, and <br />e� two storm sewers (locations shown on map overlay) which <br />channel stormwater runoff from the surrounding watershed <br />into the lake.. <br />
