Source for North American public boat and kayak launch sites?

Question

Does anyone know of a good source for North American public boat and kayak launch sites for mapping in a GIS. I would prefer a web service.

Answer 1

I am not aware of a National Dataset with this information in it. There are several regional web pages that have this information for the state/county level. Is there a specific state you are interested in?

For Example:
