MAJOR SPECIES Pink OTHER SPECIES Chum 
ESCAPEMENT TIMING Late. Sep. -Oct. ESCAPEMENT MAGNITUDE 5,000 
SPAWNING FACILITIES Rating from fair to good for both of the intertidal branches. The N. W. branch is 
considered as the main spawning stream with the N.E. branch as tributary, because of limited spawning facilities 
found primarily in the intertidal zone. 
STREAM TEMPERATURES Warm range (Estimated). 
VALLEY DESCRIPTION  Stream's course through muskeg flats at the base of Davison Mountain. Wooded upper 
slopes and along lower stream courses. 
DRAINAGE Total drainage area 5 square miles (2 square miles, 108A; 3 square miles, 108B as computed from 
Polar Planimeter). Precipitation fed, no lakes or ponds. 
STREAM MOUTH IDENTIFICATION Red channel buoy visible from intertidal zone. 
ANCHORAGE 
TRAILS AND SURVEY ROUTES Main spawning stream at N. W. corner is easily walked. Tributary spawning 
stream easily walked in the intertidal area.

BOTTOM _ Gravel, small rock, shale, boulders and bedrock. 
MARKER DISTANCE 
MARKER IDENTIFICATION 
BARRIERS N.E. spawning tributary has series of falls . 2 mile upstream with bedrock areas below, limiting 
spawning to intertidal. No barriers reported on primary spawning stream. 
TRIBUTARIES N_E. corner of intertidal zone. Stream is considered as tributary to primary spawning stream in 
N.W. corner, though slightly larger in size, due to spawning area limitations. 
SCHOOLING AREAS 
SPAWNING AREAS Shallow gravel riffles in lower stream. Stream bed becomes coarse upstream with frequent 
bedrock rapids and shale sections.
