In the Yellowstone and Lamar rivers and tributaries in the Northeast Region of the park, rainbow trout and cutthroat x rainbow trout hybrids have white tips on the anal and paired pelvic fins and must be killed. All nonnative fish, including rainbow trout, brook trout, and identifiable cutthroat/rainbow hybrids must be killed in these areas:

• Lamar River drainage including all tributaries and lakes.
• Yellowstone River below Lower Falls and above Knowles Falls, including north side tributaries.

In areas downstream of these locations, killing of nonnative fish is recommended. If you don’t know, let it go.
Smallmouth bass caught anywhere in the park must be killed and reported.
