I have tons of documents on this. If a waterway is connected to a watershed, the EPA gets to dictate how much poop is permitted into it. Then they eminent domain the boundaries along the waterway. Boundaries are called greenways.
The whole thing is a "load" if you ask me. And yes, it is scary what a mindless monster the bureaucracy has become.
