About this site
Freshwater divers will love this Lake Michigan site, known for its clear visibility and intriguing shipwrecks. The cold waters preserve wooden vessels in excellent condition, offering a glimpse into maritime history. Expect schools of lake trout and smallmouth bass weaving through the structures. The sandy bottom slopes gently, making it accessible for various skill levels. Summer brings warmer surface temps, but thermoclines demand proper thermal protection. A great spot for wreck enthusiasts and those seeking a unique Great Lakes diving experience.
