Where this section begins and ends

Loading map…

The drawn shape is the named water, matched from the official list against OpenStreetMap and accepted only because the name resolved to a single feature in this water's county.

Different sections of this water can have different rules. The exact section boundaries are not marked on the map yet; each rule above describes in plain words where it starts and ends, and that written description is the authoritative boundary. Map boundaries come water by water, never as a guess.
