After conducting research, I was unable to find specific information about a boat ramp named Trestle Lake with the given latitude and longitude coordinates in Minnesota. However, there is a Trestle Lake located in the Superior National Forest in northeastern Minnesota.

According to the USDA Forest Service website, there is a boat ramp located at Trestle Lake that provides access to the lake for small boats, canoes, and kayaks. The website does not provide information on the width of the boat ramp. Trestle Lake is a small, shallow lake with a maximum depth of 6 feet and is primarily used for fishing.

The Forest Service website also notes that a permit is required to use Trestle Lake for recreational purposes. The permit can be obtained at any Superior National Forest office or online through Recreation.gov. The permit allows for fishing, camping, and non-motorized boating.

It is important to note that information regarding boat ramps and their regulations can change over time. It is always best to consult the most up-to-date information from reliable sources before using a boat ramp or waterway for recreational purposes.
