In regard to Wayne's and 10pointer's comments, I have witnessed and caught many large browns out of zone 3 in july and august. Those fish just appear overnight it seems. I am almost positive that mdc is not loading up zone 3 with lunker browns at that time of year. Now, as far as numbers, a huge decrease in fish since 04. As far as them making it all the way to the raceways, a piece of cake at bssp. Their greatest obstacle would be the bait fishermen, and I mean no disrepect by saying that. Do the rainbow leave the warm river water as well? I can't say for sure, but I would assume so. Many stocker size fish would be caught and creeled on a daily basis and never given a second thought. I rarely fish zone 3 since the regulation changes, but I still make several observatory trips in july and espescially august. If I find a big fish, then I adhere to the new regs, if I don't find a good fish, then I return to zone 1 and 2 without ever wetting a line in zone 3. Those big browns come from somewhere, and I believe it is out of the river. In the 80's and 90's, I don't believe they clipped fins. Now it should be proof positive to know for a fact. I walked zone 3 about 3 weeks ago and did not observe even one good fish. Saw a few 3 to 4 pounders and that was it.
