Olson Lake is situated in Rock Cut State Park on the northeast side of Rockford.
Olson Lake is an artificial impoundment in the watershed of Pierce Lake. It was built in order to be a silt basin and prevent Pierce Lake from filling up with sediment. The lake was first filled in 1990, and it was 50 acres in size at the time of filling. The maximum depth was 12.0 feet with an average depth of 6.5 feet.

Olson Lake has a tremendous coverage of aquatic vegetation, consisting of coontail, Eurasian milfoil and white water lily. The lake was constructed using Build Illinois Funds and its main purpose was to provide swimming opportunities. To this end, an extensive beach was constructed on the south shoreline with a bathhouse and parking. Only a canoe or kayak launch facility is found at Olson Lake.
All fish: 2 pole and line fishing only.

Site Regulations:
Large or smallmouth bass: 1 fish daily limit; 14" minimum length limit

FISHING OUTLOOK
BLUEGILL
Improving IMPROVING
The bluegill population should be improving with the current winter drawdown helping to eliminate the overpopulation of smaller sized fish.
LARGEMOUTH BASS
Developing DEVELOPING
The largemouth bass population should turn around in the next two years. The population does have a missing year class in the 10-12 inch range coming up, which will lead to some weak fishing in 2019, but good numbers of older fish are present. Expect good fishing for 15 inch and larger fish for this year, however future years may be weak.
