First week of elk hunt
When I saw the run it was the first weekend of the elk hunt it might not be the full run but they're still going that long
Sept 1 threw 16th was the run but the 16th was the best day so many salmon to see.
Typically til the first of October, but they do their big celebration day around Sept 15th.
They were running Tuesday early evening.
I'm pretty sure it is dependent on water temperature so it can vary. If you call the visitor's center directly they can probably tell you more accurately.
September through October
