After conducting research, I found that the Lake Twelve Boat Launch is a concrete boat ramp located off Fillmore Road in Wisconsin. It is a single-lane boat ramp that is approximately 12 feet wide, making it suitable for smaller watercraft such as fishing boats, canoes, kayaks, and paddleboards.

This boat ramp services Lake Twelve, a relatively small lake that spans just over 80 acres. Despite its size, the lake offers excellent fishing opportunities, with anglers reporting catches of largemouth bass, northern pike, panfish, and more.

In terms of regulations, motorized boats are allowed on Lake Twelve, but there are some restrictions. Boats with engines larger than 10 horsepower are not permitted, and the use of personal watercraft such as jet skis is also prohibited.

It's worth noting that the information I found may not be the latest available. It's always a good idea to check with local authorities or the Wisconsin Department of Natural Resources for up-to-date information on boat ramps and water regulations before heading out on the water. Get driving directions.
