Before you fish
Fishing rules, water conditions, and access change without notice. State fish-and-game agencies update regulations annually — sometimes mid-season for emergency closures. Real-time flow, water temperature, and stocking data are pulled from USGS, NOAA, and state agencies on a delay. Outdoors is not the regulating authority. Confirm current regulations with the state agency, check flow on the USGS gauge, and verify access if a section flows through private land. You are responsible for compliance.
