Interesting read on the fall-out from a toxic spill - 5 yrs later

As interesting as the article is, keeping in mind the article is fascinated by the fact that life exists, the follow-up discussion at the end of the article is as interesting to read. Having worked in the Squamish Forest District for 2 salmon season runs in the mid 90's I enjoyed the fishing and heard much about the history of the fishery, the steelhead, the Daisy L Dam and water bypass, and worked in the forestry industry that has caused the river so many problems. Yet, as the article touches on, even after a caustic spill that wiped literally all fish from the system, the river keeps on trying to produce.
