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 !
