I understand the concern, but technically, you are off by two weeks.

They keep counting them as springers over Bonneville until June 15.... so really there's still about 90 days of counting left.

But your point is well taken. A big run usually comes in early and tails off late, with a big peak (or couple peaks) in the middle. The overall entry curve spans a wider time-frame and reaches higher in overall abundance.

If the faucet of fish doesn't really start flowing in the next week, it ain't gonna happen.
