The count I show at the falls up until the last posting was only two days of counts that are anywhere near that high. The posting before that show numbers in the single digits.
So those wouldn't be this far upriver for at least a week.
Also I've been told that they plant the smolts here in Eugene so the steelhead tend not to upriver from the planting area.
Not sure about how true that might be. But I've not heard of them being hauled out in numbers at Dexter dam the way the Chinook are.
