KETCHIKAN, FILLMORE INLET, Extreme head 
MAJOR SPECIES Pink, chum, and red OTHER SPECIES Coho and trout 
ESCAPEMENT TIMING Middle. Aug. -Sep. ESCAPEMENT MAGNITUDE >100,000 
SPAWNING FACILITIES Excellent for all species. 
STREAM TEMPERATURES Normal range. Observed 7/26/50, 51°F. ; 9/11/50, 55°F. 
VALLEY DESCRIPTION Stream cut glacial. Broad delta with extensive grass-flats. Lower valley stream cut. 
Lake upstream impounded behind old terminal moraine. Upper valley retains glacial U-shape. 
DRAINAGE Early snow fields. Aug. -Sep. precipitation fed. Some springs below talus slopes around lake. 
STREAM MOUTH IDENTIFICATION At the head of the inner lagoon. At low tide, channels of the stream 
extend across entire delta base. 
ANCHORAGE Outer chuck off small stream delta in N.E. corner. Inner chucks and lagoon are uncharted. 
TRAILS AND SURVEY ROUTES Entrance to lagoon narrow with rock on S. side extending into mid-channel. 
Passage on N. side of channel clear. Skiff may be taken short distance above high tide point on high tides. No 
trail or route other than creek bed. Difficult on high water. 
AERIAL SURVEY NOTES Aerial observations can be made of most of the stream. The maximum concentrations 
have been found in the intertidal zone and lower stream where visibility is unobstructed. Surveys to the lake are 
best made at low altitudes by light planes due to restricted turning in the narrow valley. Adequate landing and 
take-off distances in lake. 
INTERTIDAL ZONE 
LENGTH .4 miles AVERAGE WIDTH/DEPTH  150'/12" 
GRADIENT AND VELOCITIES Less than 1° at 2! per second 
BOTTOM _ Gravel to 3" diameter, sand in lower zone. 
LOW TIDE LOCATION No identifying marker. 
HIGH TIDE LOCATION At first contact with trees on N. bank. 
SCHOOLING AREAS _ Two pools about the high tide point. 
SPAWNING AREAS _ Spawning throughout the upper 2/3 of the entire intertidal zone. These spawning areas are 
excellent, with optimum gravels and currents. 
GENERAL NOTES The series of chucks and the lagoon with its restricted outlet tend to reduce the variations 
between high and low tides so that the intertidal zone of the stream has less range than other streams in this 
region. Salinities over the intertidal zone during tidal fluctuations are probably quite low. 
UPSTREAM 
LENGTH ACCESSIBLE 2 miles to lake AVERAGE WIDTH/DEPTH  50!/24" 
GRADIENT AND VELOCITIES 1° at 2! per second 
BOTTOM Gravel to 5" diameter in first mile, larger beyond. 
MARKER DISTANCE .5 miles. 
MARKER IDENTIFICATION Large log jam below a rock wall on N. bank. An alder just above is blazed. 
BARRIERS None. 
TRIBUTARIES A small tributary enters the stream . 3 miles upstream. This drains a small valley to the north. 
It is usually quite low during Aug. -Sep. and very few salmon enter it. 
SCHOOLING AREAS Pink and chum salmon school just above high tide. Resting pools are scattered throughout 
the stream. Some holes are found beyond the marker where reds are observed in August. 
SPAWNING AREAS _ The major pink and chum areas are in the lower stream. Reds enter the lake and spawn in 
the main stream at the head. Lake shore spawning occurs along most of the talus slope S. shore. This is one of 
the few lakes where shore spawning of reds has been noted. 
GENERAL NOTES This is one of the best streams in the Portland Canal area. Its production has continued to be 
very good in an area where most other streams have been reduced to very small runs. It is believed that the 
sheltered waters adjacent to the stream are instrumental in protecting young migrants during the early stages 
of saltwater.
