Not as clear as it does now. The Arrow lakes acted as as the filter but the Kootenay had lots of silt for most of the summer Also the Didymo algae filters a lot of particulate that stuff showed up about 40 years ago.Curious.
Before the Columbia River dams and reservoirs were constructed in British Columbia, did the Columbia River near Castlegar ever run clear in the summer or only in late autumn and winter?
More fish but less size My uncle would take the train and drift from the Brilliant Falls down to Trail, he and his brother would have enough fish to get the family through the winter none over 3lbs. He told me stories of getting 20lb trout out of Trail creek pretty sure they were steelhead. There were a lot of Dollies in the system before the Dams and lots of coarse fish. They have been replaced with Walleye.Thanks Grant.
Kootenay Lake was insufficient to settle out the glacial till? Interesting. Did the glacial till that the Kootenay River would have once upon a time dumped into Kootenay Lake enhance productivity in Kootenay Lake? The effluent from the Sullivan mine operations at Kimberley was once upon a time a source of fertilizer for Kootenay Lake until Cominco spent about ~C$10-12 M in the late-70s cleaning it up.
So the Columbia River below the Lower Arrow Lake would then likely run clean or cleanish for most of the summer. I have trouble imagining the trout fishery being as rich as it is now. How do the old timers describe the trout fishing pre-dams?
It would be great to see a map of the old Arrow Lakes. I managed to see the unflooded lower Kootenay River valley in 1968 but never managed to visited the unflooded Arrow Lakes/Columbia River valley.
Getting them up over the wall is the easy part....getting the juveniles back to the ocean is a whole other story unfortunately :crying:With the Columbia River Treaty being negotiated right now the Environmental impacts are at the top of the list for all those concerned. I can only hope that the quest for the all mighty dollar does not hider that position. The best comment I have heard is from a First Nations Rep. "if we can send a land rover to Mars we can get a few fish over a concrete wall"
For sure, but I think it can be done just takes some major coordination between all the agency's that manage the system.Getting them up over the wall is the easy part....getting the juveniles back to the ocean is a whole other story unfortunately :crying:
Would be great if the will is there to bring back some Columbia runs back to Canada. From what Ive been told likely never get fish over Mica dam but even getting fish into Arrow ,Slocan and Salmo drainages would be great . Likely not in my fishing time either but sure would be nice to see it.The early spring run of Chinook-Kings were supposed to be the largest sized fish on pacific coast and think they travelled furthest too, all the way to headwaters of the river.From what I was told they were in 50-70 pounds range and have seen picture of fellow catching them in down town Salmo in early part of 1900,s.Hope it happens again.
