Massive Chemical Spill wipes out Salmon and Trout in Cheakamus River British Columbia

A massive spill of caustic soda has killed all salmon and trout in the
Cheakamus River North of Vancouver. This year is the high cycle for pink
salmon in southern BC. The Cheakamus supported runs of a million or more
fish into the 1950's but the run was entirely destroyed by a hydro-electric
development with 10 years. Restoration work had restored the run to 150,000
plus fish by 2003 but a 100 year flood in that year greatly reduced fry
survival. Substantial numbers of adult pinks were in stream when the spill
occurred as were mature king salmon and 3 year classes of juvenile
steelhead. and the 2004 class of coho. Some fish have survived in artificial
spawning and rearing channels plus a small hatchery:
