According to the Wisconsin Department of Natural Resources, the Saint Croix River -- Somerset Landing boat ramp is a concrete ramp that is 28 feet wide and has a slope of 8%. It provides access to the Saint Croix River, which is a popular destination for boating, fishing, and other water activities. The river serves as the border between Wisconsin and Minnesota, and is known for its scenic beauty and recreational opportunities.

The Wisconsin DNR states that all types of watercraft are permitted on the Saint Croix River, including motorized boats, canoes, kayaks, paddleboards, and sailboats. However, there may be restrictions in place during certain times of the year or in specific areas of the river, so it's important to check with the DNR or local authorities before launching your vessel.

As of August 2021, the latitude and longitude coordinates provided in the question match those listed on the Wisconsin DNR's boat launch locator website. However, it's always a good idea to double-check this information before heading out on the water to ensure accuracy and avoid any potential navigational issues.
