*During the hotter months of summer we do not recommend fishing a majority of the Firehole river, sections of both the Madison and Gibbon Rivers due to high water temps and recommend you do the same.
Current Report
Flows have dropped to consistent summer levels, and the water temperatures are starting to rise, which is not the best for our finned friends. On days when water temps hit 70°F, consider fishing other rivers to avoid harming trout populations. This river still fishes well in the morning, but it’s best to be off the water before noon to avoid stressing the fish. PMDs, White Miller caddis, as well as tan and olive caddis, are fishing well.
