Daily limit changes at Flaming Gorge
Reservoir: Starting in 2021, the daily limit
for bass at Flaming Gorge Reservoir will be
three fish (largemouth and smallmouth
combined). The kokanee salmon limit is also
changing. You may keep a daily limit of up to
four trout and/or kokanee salmon (a combined
total), excluding lake trout. These changes
were made in coordination with Wyoming to
ensure consistency across the reservoir. See
page 30 for all of the rules specific to Flaming Gorge Reservoir-------------------
