Knoll Lake Campground is closed for the winter. Only boats with a single electric motor are allowed on Knoll Lake. The lake level is low and the boat launch is out of the water, making launching a boat difficult. No gas-powered motors. Green sunfish were illegally stocked into the lake, please lethally remove all green sunfish caught. Reminder: The statewide limit is 4 trout per licensed angler per day. Ice is present, limiting angling access. The ice is not safe to walk on.
