Larson Marsh is a 12-acre marsh that was acquired from Maurice and Ruth Larson in 1981. Prior to acquisition, the area was farmed. However, half of the site would regularly flood in the spring due to the presence of a large pothole.
 
Assistance from the state's wildlife habitat stamp fund grant program allowed the conservation board to make wildlife habitat improvements on the area. The large pothole was deepened, and two islands were created within the pothole. Native prairie grasses and forbs were planted on the islands and other areas around the pothole.
 
Today, the marsh is a public hunting area. Hunting and trapping are allowed. Please remember to get permission when hunting within 200 yards of any occupied building, even when hunting public land. Non-toxic shot is required at this site.

Pets must be kept on leashes from March 15 to July 15. Pets must be kept under control at all times.
 
The conservation board's Environmental Education Program also uses the marsh as an outdoor classroom.
