Yeah, a side note about the Barge factor. From the Biologist accounts that I read, the fish seemed "confused" after being released from the barge. Orientation. I started to think, Ill bet the Smolts need the whole trip downstream "In the river" to gain the Perspective and Orientation they need to return. When Key sections of the river are left "un-navigated" the fish become confused and unable to put the whole trip in perspective. Like falling asleep in a car during a trip, when you wake up, first thing you ask,"where are we?"
I am looking forward to the study results on the spill when they become available.
