Based on the latest information available, the Leighton Lake State Water Access Site boat ramp in Minnesota is a concrete ramp that is approximately 20 feet wide. This boat ramp services Leighton Lake, a smaller-sized lake located in the northern part of the state. The lake is primarily used for fishing, with various species of fish available for angling, including black crappie, bluegill, largemouth bass, northern pike, and yellow perch.

As for the kind of craft allowed on the water, there is no specific information available on the Leighton Lake State Water Access Site website. However, it is safe to assume that typical watercraft such as fishing boats, canoes, and kayaks are permitted on the lake. It is always recommended to check with local authorities or the specific water access site for any regulations or restrictions on the use of the lake and boat ramp.
