B. C. Hydro proposed 287 kV transmission line Kitimat to Terrace: Preliminary environmental assessment of fish and wildlife values

Technical Report:

Abstract

The proposed two corridors for an additional 278 kV transmission line from Terrace to Kitimat, British Columbia were referenced for fisheries and wildlife sensitivity and impact. Route A parallels the existing powerline down the eastern edge of the Kitimat valley while Route B follows the western edge and is 12 km shorter. Fisheries values are paramount in the study area with populations of steelhead, pink, coho, chinook, chum and sockeye in both the Lakelse and Kitimat drainages. Recreational species are of strong secondary importance and support a viable tourist industry. Wildlife values are best represented by moose, bear, fur-bearers and waterfowl. Clearcut logging has depressed populations in the study area but regrowth of essential habitat and cover is allowing some species to increase in number. Trumpeter swans utilize the valley as a migration route while some remain as residents in warmer winters. The two proposed corridors were evaluated on a resource basis to determine the least impactive and sensitive route, with a general rating evolved with common criteria. The rating of Route B was significantly less sensitive than Route A, due to Route B being significantly shorter and drier. 2 figs.
