Yellowstone Park, August 10th, 2021
Hoot owl closures remain on all park streams. There are no such restrictions for fishing park lakes. Go to the Yellowstone National Park Fishing Restrictions web site for more details, and note that if stream conditions worsen the park suggests that fishing in these waters could be curtailed.
An interesting happening is that cutthroat trout are being caught in the Madison River. Where they came from is a good question.
