Wow! The Falls count increased 153 in one week, and the Reiter count increased by 3 in the same time frame.

If they don't plant above the falls (or somewhere else on the SF above the hatchery, then the difference is only attributable to straying, from what you're saying.

Is it possible that the low returns at the hatchery are attributable to high water temps, then? They're blowing by the hatchery looking for some O2?
