So just give individuals/companies private property rights in the waterways. They will sue the hell out of the coal companies.
Public waterways are just the modern version of the "commons" problem. Everybody uses/abuses them without having financial responsibility. So give someone some vested interests and they will make the efforts to maintain/improve them. Of course they charge for their use, but you don't get things for free regardless of what the politicians promise.
