''Q. What is the speed limit for boating on lakes?
A. On lakes and ponds that allow for the use of motorized boats, vessels are not to exceed a speed of 5mph within the “Shoreline Safety Zone,” defined as the portion of the surface area of public waters within 200 feet of the shoreline. A "no-wake speed" is also required within 200 feet of marked swim areas and other vessels, including canoes and kayaks.''
