Wolf Lake

William W Powers Conservation Area, is a state-owned facility, and the only state park in the City of Chicago. It protects a portion of Wolf Lake, one of the five shallow lakes that once graced the Calumet area (two are now completely or mostly filled in).

During spring, fall and winter (if the lake remains unfrozen), large numbers of waterbirds appear on the lake. These include Common Loons, Horned Grebes, swans (Mutes are residents; Tundras are less common) and many ducks. The woods on the northeast side can be very productive for migrant songbirds.
