Waubeeka Lake is fed primarily by artesian springs, and is impounded by three dikes on the western, eastern and southern shores. The West Dike consists of a road embankment built along a natural saddle which lies between hills forming a ridge along the western and southern fringes of the lake. The East Dike is a 225-foot-long by 3-foot-high earthfill structure with a vertical downstream masonry face and an inclined upstream face which is entirely covered with riprap. The southern Dike consists of a landfill deposited in a saddle between hills skirting the southern perimeter of the lake. The width of the South Dike is over 100 feet, while the height is only two to three feet. Visual inspection of the dikes indicate that the East and West Dikes are in poor condition. The growth of trees along the dikes will deteriorate these structures and induce seepage along the root networks. Also, high winds may uproot the larger trees, causing an immediate failure. No damage due to the breach of the structures impounding Waubeeka Lake is anticipated and the hazard classification of the West Dike, specifically, is LOW based on the dam breach analysis.
