Approximate - nearest available gauge. Use as general reference only.
A cement ramp leads into (out of) the water at the end of the course. Sidewalks along the course allow boaters to carry back up for repeat runs. (A few who frequent "the Race" with longer/heavier boats may even have a set of wheels they can strap onto one end of their boat so they don't have to carry the full weight of it all the way up the 'race'.)
