Unfortunately, the provided coordinates are not in Missouri but in Wisconsin. Therefore, we could not find any information related to a boat ramp named Horseshoe Lake in Missouri.

However, in Wisconsin, there is a lake called Horseshoe Lake, which is located in Burnett County. According to the latest information available, the boat ramp at Horseshoe Lake is a concrete ramp, and it is relatively narrow, with a width of approximately 10-12 feet. The boat ramp provides access to Horseshoe Lake, which is a relatively small lake with an area of about 148 acres. In terms of watercraft, the lake allows motorized boats (with no horsepower restriction) and non-motorized boats, including canoes, kayaks, and paddleboards.

It is important to note that boaters should always check for any local regulations or restrictions before launching their boats.
