hydro dams, mining, agriculture, oil and gas exploration can all cause harm

 

Dams

 

Millions of salmon have been lost in B.C. due to hydroelectric dams or dams for municipal water supplies. There have been big losses on the Alouette, Bridge, Capilano, Coquitlam, Cheakamus, Nechako, Puntledge, Seton, Stave and the middle Shuswap rivers. Dams can fully block access to salmon spawning areas. They also dramatically change the natural waterflow regime in ways that can cause long term damage to salmon habitat.

Hundreds of “run-of-the-river” projects are now in front of provincial regulators for approval. Although these are touted as environmentally benign by their proponents, there are huge implications for salmon streams ranging from harmful changes to the waterflow regime downstream to impacts during construction.

Pesticides
Pesticides and herbicides are used over vast areas by forest companies and railways. Many pesticides and herbicides are directly lethal for salmon, particularly juveniles. They can also bioaccumulate in the food chain to become much more toxic. We need a province-wide ban on cosmetic pesticides and a comprehensive plan to reduce or eliminate pesticides and herbicide use in agriculture and forestry.

Agriculture
Cattle can easily destroy stream banks and spawning grounds. Heavy use of fertilizers in the Fraser Valley affects the water quality of the groundwater and the Fraser River.

Mining
Mine effluent has impacted fish stocks in many systems. The Tsolum River and the Coquihalla River have been particularly impacted. Britannia Mines has had the most toxic runoff in Canada, flowing directly into Howe Sound – a situation now receiving some treatment. The impacts from acid mine drainage can last hundreds of years.

Water use
Several hundred fish-bearing streams in B.C. have flows that are too low for proper fish passage or for juvenile rearing. The needs of fish and other species is not given priority when water use licenses are granted. We need a new Water Act that gives conservation and fish protection top priority.

Roads and rail lines
The rugged terrain in B.C. forces many roads and rail lines to closely parallel salmon streams and rivers. Streambanks are destabilized and streamside vegetation is removed. Impassable culverts have destroyed or degraded extensive salmon habitat.

 

Backyard Action
Along Your Shoreline Shorelines provide essential habitat for many plant and animal species. Protecting and enhancing these important corridors is important work. You can help protect your local shoreline.
