Fishing Swimming
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. The Outdoors App 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.

About
Crater Lake is the deepest lake in the United States with a maximum depth of 594 m (1,949 ft) per USGS, formed in the caldera of Mount Mazama some 7,700 years ago. It is famous for its intense blue color, a result of the lake's exceptional clarity (visibility >40 m). Located entirely within Crater Lake National Park. Fishing is allowed without a state license — non-native rainbow trout and kokanee salmon were introduced 1888-1941 and persist; the lake had no native fish. Access is via the steep Cleetwood Cove Trail (the only legal access to the shoreline).
