It is not fed much by local springs, nor is it a stagnant pond. It has a healthy flow-through of water from the Fox River; drainage area upstream is 358 square miles.
Before the dam at Waterford was erected, there were two lakes: Tichigan Lake and Buena Lake. The rest was a riverbed, much like today’s Fox River between Big Bend and Bridge Drive. The roughly five-foot high dam at Waterford extended the surface area of the waterway to its present 1100 acres. Hydrologically, most of our waterway is best described as a reservoir behind a dam; an impoundment.
This is a fine waterway, with a long shoreline, about 24 miles total. It offers varied scenery, good fish habitats and good fishing. Plus waterfowl hunting. The downside is that all impoundments tend to fill in with silt from upstream. In many areas, the water depth has become borderline for most motor-boats. Due to the sticky nature of our silt (often dubbed “muck”), it is also dangerous to swimmers, as anyone putting feet and legs down in it risks getting stuck.
