Island Lake Is a spring-fed lake with crystal clear waters; three miles long and 1 1/2 miles wide. It has many points, rock bars and islands with deep water between. It is one of the best lakes in the area for walleye catches, along with northern pike, small-mouth bass, large perch and bluegills. The beautiful autumn colors, the fine fall walleye fishing and hunting also make this an excellent time to vacation at Valhalla!
