Here we dive into the top 10 clearest lakes in Wisconsin, from the hidden gems to the famous clear waters that every outdoor enthusiast should add to their must-visit list.
#10: Shell Lake
Shell Lake, located in Washburn County, is the state’s largest landlocked seepage lake. With a maximum depth of 36 feet, its crystal waters are well-loved by both anglers and swimmers. Its sandy bottom contributes to its clarity, making it a popular destination for snorkeling and scuba diving.

Visitors often comment on how they can see deep into the water, which speaks to Shell Lake’s impressive clarity.
#9: Tomahawk Lake
Tomahawk Lake, part of the Minocqua Chain of Lakes in Oneida County, is a favorite for both residents and visitors alike. The lake stretches over 3,392 acres and reaches depths of up to 84 feet. One of the lake’s most remarkable features is its strikingly clear water generated by its deep, cold waters and minimal boat traffic. This lake provides a serene environment, ideal for fishing, paddling, and simply enjoying the clear blue of the water.
#8: Castle Rock Lake
Castle Rock Lake is Wisconsin’s fourth largest inland lake, with a surface area of 16,640 acres. It’s located in Juneau and Adams counties and despite its size, it maintains a high level of water transparency. Castle Rock Lake’s sandy bottom contributes to its clarity, and it has become a hotspot for various water sports. It does not quite reach the depths of some of the other lakes on this list, but its clear water makes it an attractive destination for those looking to boat or fish in clear conditions.
#7: Green Lake
Green Lake is Wisconsin’s deepest inland lake, with depths reaching 237 feet. This intensity of depth contributes to its clear icy blue waters, which are strikingly beautiful. The lake has a relatively low nutrient content, which reduces the growth of algae and contributes to its clarity. Green Lake’s allure is not just in its clarity but also in its cultural and historical significance. It’s a year-round destination with activities ranging from swimming and boating to ice fishing and cross-country skiing.
#6: Blue Lake
True to its name, Blue Lake boasts exceptionally clear and blue waters. This small, private lake located in Oneida County is managed as a trophy bass fishery, but it’s the clarity of the water that really turns heads. Blue Lake stands out because it is an oligotrophic lake, meaning it has low levels of nutrients and, consequently, minimal algal production, which helps the water remain clear. With depths up to 49 feet, the lake supports not only a variety of fish but also offers extraordinary sights for those who enjoy diving or snorkeling.
#5: Black Oak Lake
Black Oak Lake near Land O’ Lakes is often cited as one of the clearest in Wisconsin. It reaches depths of 85 feet and stands out for its transparency. With a largely undeveloped shoreline, Black Oak Lake offers a slice of wilderness to its visitors. The clarity of the water is such that it’s possible to see the shadow of your boat on the lake bottom on a sunny day. Fishing is a popular activity, with the lake supporting robust populations of walleye and smallmouth bass.
#4: Carlin Lake
Carlin Lake, another hidden gem in Vilas County, is a private lake that is known for its serenity and exceptionally clear water. With a maximum depth of about 35 feet, Carlin Lake’s waters are calm and inviting. It’s noted for having very little boat traffic, which helps maintain its peaceful ambiance and water clarity.

With limited development along its shores, Long Lake presents a clear, unpolluted body of water that recreational boaters and swimmers enjoy immensely. Its clarity is a showcase of preservation and responsible recreational use.
#2: Bond Falls Flowage
While technically a reservoir, Bond Falls Flowage in the Upper Peninsula merits a special mention. This body of water, though it has man-made origins, possesses the kind of transparency you’d expect from a natural lake. The water here is filtered by stands of old-growth forest, which meticulous conservation efforts have protected. This results in exceptional clarity. Paddlers and fishermen frequent this spot, taking advantage of both the serene waters and the striking clarity beneath their boats.
#1: Big Sand Lake
Topping the list is the pristine Big Sand Lake, located in Phelps, within the boundaries of Vilas County. This breathtaking lake spans 1,402 acres and plunges to depths up to 56 feet. The clear waters are almost Caribbean in hue, and visibility extends so far down that it almost seems unreal. Big Sand Lake is a quiet, mostly recreational lake with minimal boat traffic, which helps preserve its clarity. The lake also benefits from strong community and conservation efforts aimed at maintaining its cleanliness and water quality.
