Big Stone Lake is very popular with anglers who may catch more than 30 different species of freshwater fish. The most popular are walleye, northern pike and bluegills. The lake is stocked once every two years with 7,000,000 walleye fry. There are 12 public accesses along the length of the lake for fishing use.
The lake boasts two state parks: Hartford Beach State Park in South Dakota and Big Stone Lake State Park in Minnesota. These offer boat launch areas, beaches, campgrounds, hiking trails and other amenities.
