The lake has a small public boat launch, but the use of electric or gas motors is restricted in favor of smaller vessels, as the lake itself is no more than 4 feet (1.2 m) deep.

[1][4] The waters may be difficult to fish due to its grassy nature and very loose marl bottom, but common fish within the lake include smallmouth bass, rock bass, sunfish, and several other small varieties.

Other activities include hiking, biking, and cross-country skiing along the 5.5 miles (8.9 km) of trails cutting along and through the forest around Marl Lake.

[5] Kayaking, bird watching, photography, shore fishing, and picnicking are also popular activities.
