ESCAPEMENT TIMING Late. Sep. -Oct. ESCAPEMENT MAGNITUDE >10,000 
SPAWNING FACILITIES Good facilities found throughout the lower accessible stream. Spawning gravels 
become progressively limited upstream.

VALLEY DESCRIPTION Stream flows across low flat country at the base of Alava Ridge. Upper valley lies 
between ridges with small ponds throughout. Large lake basin 4 miles upstream between ridges. 
* DRAINAGE 8 square miles (Polar Planimeter). Precipitation fed through lake system. Two small lakes on N. side 
of accessible stream. Extensive muskeg areas. 
STREAM MOUTH IDENTIFICATION Piling onN. side of S. point. Trap storage area. 
ANCHORAGE Piling just inside S. point may be used by smaller vessels. 
TRAILS AND SURVEY ROUTES Difficult to walk during high water. Game trails along S. bank can be fol- 
lowed with some difficulty. Trapper trail on S. ridge begins in S.E. corner of the cove. 
AERIAL SURVEY NOTES Very restricted visibility under most light conditions. Amber water and dark bottom 
limit salmon observations. Deep canyon with high trees along banks requires near vertical course. 
INTERTIDAL ZONE 
LENGTH .-3 mile AVERAGE WIDTH/DEPTH 40-50'/12" 
GRADIENT AND VELOCITIES .5-1° at 2' per second 
_ BOTTOM Gravel, some boulders. 
HIGH TIDE LOCATION  .1 mile above head of grassflats. Blazed tree on S. bank, large log in midstream. 
SCHOOLING AREAS _.1 mile of stream above head of grassflats offers schooling conditions. Large concentrations 
have been observed in this area. 
SPAWNING AREAS Upper intertidal area more coarse than mid-tide range. Spawning observed throughout most 
of intertidal zone, including very near low tide mark. (Double channel low tide outlet) 
GENERAL NOTES 
UPSTREAM 
LENGTH ACCESSIBLE .8mile AVERAGE WIDTH/DEPTH 35-45'/10-12" 
GRADIENT AND VELOCITIES 1-2° at 2-3! per second 
BOTTOM Gravel, coarse rock and 20-30% bedrock, increasing upstream. 
MARKER DISTANCE .8 mile. 
* MARKER IDENTIFICATION Barrier falls. 
BARRIERS _ Two falls separated by cataracts (Three 4-5! falls). Lower falls 15', upper is 8'. May offer laddering 
possibilities. 
TRIBUTARIES Small, steep tributary enters just above high tide from lake on N. side(Less than . 1 mile from 
outlet). Small tributary on S. bank . 3 mile above high tide accessible for short distance to salmon. 
SCHOOLING AREAS Pools scattered throughout stream. Most schooling obseryed in lower stream pools and at 
deep pool at base of terminal falls. 
SPAWNING AREAS Main upstream spawning has been observed in the first . 3-.4 mile of stream. However, 
spawning occurs throughout stream, including sections that are generally not considered spawning areas.
