Coles Creek Boat Launch Ramp

I was out using the ramp on September 11 trying to get on my pontoon when I slipped on the ramp and slid approximately 5 foot into the water, got up and went down again. Then my wife did the same. These ramps should be chemically cleaned to prevent this from happening and to keep the ramps safe for everyone. My shoulder is till bothering me from the fall and don't want this to happen to someone else
