Lasalle Cooling Lake

LaSalle Cooling Lake offers excellent launching facilities for motorboats and larger recreational vessels in Marseilles, Illinois. The access site features **three concrete boat ramps** and a spacious paved parking lot accommodating 140 vehicles with trailers, plus ADA-accessible facilities. The lake allows boats up to 40 mph (with no-wake zones observed), though vessels under 14 feet are not recommended for this water body.

**Important considerations for paddlers and boaters:** Plan extra time when launching from the northern shores, as you'll need to travel the length of the lake to reach the southwestern ramp area. The lake features a riprapped shoreline with no natural beaching areas, so plan accordingly. Zebra mussels have been documented in the lake—inspect and clean your vessel before launching and departing to prevent the spread of this invasive species. Access the site via I-80 near Seneca, with multiple highway route options from northern Illinois (I-39, Route 23, or Route 47).
