KETCHIKAN, PORTLAND CANAL, Halibut Bay, N.W. head 
MAJOR SPECIES Pink and chum OTHER SPECIES 
ESCAPEMENT TIMING Middle. Aug. -Sep. ESCAPEMENT MAGNITUDE <10,000 
SPAWNING FACILITIES Limited. 
STREAM TEMPERATURES Range 50-60° F., estimated. 
VALLEY DESCRIPTION Stream cut glacial. 
DRAINAGE Small lake fed by early snow fields, Aug. -Sep. precipitation. 
STREAM MOUTH IDENTIFICATION N.W. head of Halibut Bay. Falls visible from mouth. 
ANCHORAGE Off delta in 2 fathoms of water, N.W. shore. Steer along E. shore past 1 fathom bar several hundred 
yards S. of point on W. shore. 
TRAILS AND SURVEY ROUTES Easily walked flats to barrier falls just above high tide. 
AERIAL SURVEY NOTES Not usually surveyed by air. 
INTERTIDAL ZONE 
LENGTH .5 miles AVERAGE WIDTH/DEPTH § 100'/18" 
GRADIENT AND VELOCITIES Less than 1° at 2' per second 
BOTTOM Sand, rocks. Most of zone heavily covered by Algae. 
LOW TIDE LOCATION Constriction at head of bay. 
HIGH TIDE LOCATION Just below first contact of stream with woods. 
SCHOOLING AREAS Limited. 
SPAWNING AREAS Limited to area near high tide. 
GENERAL NOTES The lower intertidal zone is heavily vegetated and without any spawning potential. The upper 
portion is sand, with a limited amount of usable gravel right about the high tide mark. Current is generally very 
slow and is believed to be below adequate spawning velocities. 
UPSTREAM 
LENGTH ACCESSIBLE .1 miles MARKER DISTANCE .1 miles 
GRADIENT AND VELOCITIES Over 1° at 3' per second 
BOTTOM Rocks and boulders, pockets of gravel. 
MARKER IDENTIFICATION Barrier falls in a series of drops, the lowest being about 15' in height. 
BARRIERS Barrier falls. 
TRIBUTARIES Small tributary enters upper intertidal zone on east side. Some spawning occurs upstream, though 
limited. 
SCHOOLING AREAS Some small pools, scattered. 
SPAWNING AREAS Limited to gravels occurring in pockets. 
GENERAL NOTES Very little gravel occurs in this short upstream area, being mostly concentrated around the 
high tide area. However, as has been observed in other streams similar to this, the rocky portions may be used 
for spawning by the salmon with some limited success. Both pink and chum salmon have been observed spawning 
in the high tide area. No other species have been observed.
