More Information
Landscape
The Stuart-Takla experimental watersheds are located in the northernmost portion of the Fraser Basin. The site is comprised of salmon spawning streams (Bivouac, Forfar, Gluskie and 0’Ne-ell creeks) and small headwater streams (Baptiste drainage). Around 40% of annual precipitation falls as snow. The surrounding mature forests are comprised primarily of hybrid White spruce, Subalpine fir and Lodgepole pine. The bedrock geology of the area consists of metamorphosed fine clastic sedimentary rocks with intrusive granodiorite.
