Re: Yellowstone National Park
Typically the Salmonflies migrate up the Firehole very quickly and the hatch last only a week at best. This year the hatch should be a little later due to the higher snowpack that we have so far. You may get lucky and still have the bugs out on the Firehole if the snow keeps piling up and we have a cool spring. Only time will tell. Good luck with your trip and you could always head over to the Henry's Fork where the bugs should be in the Box Canyon area around this time.
