Craa have the fish ladder also dam at Kraft property, where after the fish ladder, Craa bring all the fish up to Norvall for hatchery and release back above the Norvall.
That a lot of barricade to stop the fish go up stream all the way to Norval, and above Norval all the way to Caledon.
So far I know, Atlantic need cold water for the spawning, and the credit below Norval is not cold enough for Atlantic spawning.
I see every years at CRAA statistic for Atlantic Salmon, have increase the return back at Credit, but most of the Atlantic is from hatchery, and not natural reproduction.
Due the shallow water on the credit, and a lot of barricade all long the credit, that make hard time for Salmon and trout go up stream for spawning, special for Atlantic.
I do believe this petition is not for Chinook only, but also for Atlantic, Brown, Steelhead, and other species.
