I was sitting around the house with a sick b-day girl yesterday and happen to catch a program on PBS regarding the Sacremento River system. I thought the Sac was a much bigger river than what I appeared on the tv screen. Any how long story short the program was filled with a multitude of trout/salmon bioligists and the impact man has had on wildlife on the Sac.. I watched around 45 minutes of the program before it went off and it appeared to revolve around the expansion of the dam. The dam was originally built to be expanded upon upwards of 200ft, making human expansion possible at a later date...Well, that later date is now. Anyhow it was an interesting 45 minutes and I wish I could have sat through the whole thing. There was also a guide by the last name of Trout, who spoke of fishing a tributary on the Sac after a trail toppled over with a trail cart of pesticide spilling it's 45 thousand gallons killing all the fish in the tributary. He also spoke of the iron mines (Iron Mountain) and it's effect on the tributary. They also did an interview with a man who is in charge of taking the mineral deposits, out of the water that are responsible for killing fish. Really, really interesting!
Anywho, the whole thing brought to mind the topic of trout mortality and the thread posted. All of the biologists said temperatures above 65 degrees weren't lethal but added a tremendous amount of stress to the fish. Speeding up there metabolism and making them hungry but also taking oxeygen out of the water making conditions extemely uncomfortable! All an all had you watched the program you'd understand why I though it looked very similar to the conditions refered to on that post, minus the droubt like conditions. There were several other factors included ie; irrigation, research (abroad), and conservationists...It also starred the McCloud River, which is home to the McCloud River rainbow trout. I believe is currently being protected (or an attempt is being made) by Orvis and TU..
By the looks of things it looks like that tributary doesn't stand a chance, it appeared as if the local officials already had there mind made up on expanding the dam another 20 ft putting some streams deeper and some more dried out!
Who else got to watch it...I don't have cable around the house, and I don't watch a lot of TV. I know PBS is a lost channel around most households but I hope someone caught a glimps of it. Hope someone else did and would love to hear some feedback!
