  3. Emergency orderEmergency orders in effect today override everything else. They sync quietly when the phone has coverage and never lock you out of the app.

Where this stretch 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.
