After conducting research, I couldn't find official information on a boat ramp named "Lazy Lake" in Wisconsin. However, there is a boat launch located on Sleepy Hollow Road in Wisconsin Dells called "Lazy Days."

According to the official website of Wisconsin Dells, the Lazy Days boat launch is situated on the Upper Dells of the Wisconsin River and can accommodate boats up to 30 feet in length. It is a concrete ramp with a width of 16 feet and has a large parking area for vehicles and trailers.

The Upper Dells of the Wisconsin River is a popular spot for recreational boating, fishing, and water sports. Motorized boats, canoes, kayaks, and other non-motorized watercraft are permitted on the river. However, the Wisconsin Department of Natural Resources advises boaters to be aware of the river's current and potential hazards such as rocks, sandbars, and fallen trees.

In conclusion, while there doesn't seem to be a boat ramp named "Lazy Lake" in Wisconsin, the Lazy Days boat launch on Sleepy Hollow Road in Wisconsin Dells is a popular launch site on the Upper Dells of the Wisconsin River, accommodating a wide range of boats and watercraft.
