Yellowstone National Park

Now that tourist season has slowed, and we have a few weeks left before the fishing season closes for the majority of the systems, it's time to swing some soft hackle! Baetis, midges, pheasant tails and a number of other classics will work. Remember the Gardiner and Madison will remain open all year.

Floy Tags

Park biologists are conducting a study to determine fish movement patterns and population sizes in Yellowstone Lake and several other park waters. Biologists have attached a Floy tag near the fish’s dorsal fin. The tags are typically orange or yellow in color and have a unique identification number.

If you catch a tagged cutthroat:

1. Record the tag number (photo or written) and release the fish unharmed.
2. Note the location the fish was caught.
3. Call or text 406-404-4877 and report the tag number and location of catch.
4. If the fish accidentally died, please include that detail in your report.
