The North Channel is a popular place for fish throughout the year, but in winter particularly. During the winter, the discharged water from Unilever (formerly Lever Brothers) tends to be warmer than water in other areas of Wolf Lake. It tends to be open water when the rest of the lake is frozen and attracts a variety of waterfowl. Runoff from Indianapolis Boulevard flows through Roby and Forsythe Pump Houses. Although Wolf Lake is spring-fed, discharge from Unilever provides a stable base flow of at least 16.5 cubic feet per second or 11 million gallons per day.

Exit Forsythe Park, turn right at Indianapolis Blvd. until you can make a U-turn and travel west. At first stop light, turn left past the Cargill plant, then turn right and proceed west on 112th St. At Avenue E, turn left into Eggers Grove, proceed to the far parking lot.

En route to Eggers Grove, note the oldest known monument in Chicago, the 15 ½ foot-high sandstone obelisk, located near the entrance to where the State Line Generating Plant once stood. It stands at the northern end of the state line that was the surveyed boundary between Illinois and Indiana in 1830. The Illinois-Indiana State Line Boundary Marker, erected in 1838, was declared a Chicago landmark by the City Council in 2002.
