For many Fraser River odd Pink years after 1913 , no pink salmon were
seen on their spawning grounds above Hells Gate !
By 1944 the blockages at Hells Gate was still the major cause of the
continuing poor runs of returning Fraser River Sockeye and Pink Salmon
Two major salmon ladders were built in the winters of 1944 to 1946 ,
one on each bank of the river .
A new single "Low Level ", left bank salmon ladder was constructed in
1966 , with a low river level, left bank operating range of 10 feet .
Today the Fraser River discharge at Hope B. C. is 19% lower than
average and the low river operating range of the 1966 salmon fish way
has probably reached near the operating range of 10 feet ?
The Hell Gate slides of 1913 and 1914 caused a estimated drop in
abundance of Interior Pink salmon to about one quarter of that before
1913 ! Today the adjusted salmon fish ways probably has only the
1966 left bank low level salmon passage operating during the very low
water levels in the Hells Gate Canyon area ! This could be only
verified by the Pacific Salmon Commission or D. F. O.
To achieve historic levels of over 22 million Interior Pink Salmon or
more , "there must be no OBSTRUCTIONS to the migration of salmon up
and down the Fraser River " Quote by the I. P. S. F. C. 1974 !
