KETCHIKAN, BEHM CANAL, RUDYERD BAY, NORTH ARM, W. shore . 8 miles 
MAJOR SPECIES Pink OTHER SPECIES Chum 
ESCAPEMENT TIMING Middle. Aug. -Sep. ESCAPEMENT MAGNITUDE 10,000 
SPAWNING FACILITIES Good, though limited to sections of the stream suitable for spawning by stream current. 
STREAM TEMPERATURES Normal range (estimated). Stream accessible to salmon combines Nooya Lake 
temperatures and the N. tributary temperatures from early snow fields in a high cirque and the ridge between 
Rudyerd Bay and upper Granite Creek lake system. 
VALLEY DESCRIPTION Glacial. Nooya Lake valley lies W. of the confluence with the steep stream-cut 
valley entering from the cirque N. of the outlet. Nooya Lake lies in the basin of the glacial valley with its upper 
valley turning N. to the divide. Steep valley walls, timbered in the valley and lower slopes, bedrock extensive 
in upper drainage. 
DRAINAGE A small stream that drains Nooya Lake at an altitude of 260 feet. The total drainage of the lake and 
creek is 10 square miles. The average discharge of the creek is 85 cubic feet per second (estimated). The N. 
tributary drains 2 square miles of this area and is usually low during the salmon runs. 
STREAM MOUTH IDENTIFICATION Stream mouth lies W. of small point on W. shore .8 miles beyond 
N. point of entrance to N. arm. Timbered lower slopes and valley. Stream bed along E. side of delta. 
ANCHORAGE Intertidal delta extends to a line between the outer point and the S.W. shore. Better anchorage 
in cove opposite Nooya Creek (K 40), S.E. of N. point. 
TRAILS AND SURVEY ROUTES Blazed trail leads to Nooya Lake along W. side of Creek. May be followed 
to point near falls, then cut through brush to creek. 
AERIAL SURVEY NOTES Aerial visibility adequate during good light conditions. Bright morning shadows 
restrict lower stream observations. Mid-day and afternoon shadows over entire stream offer better visual conditions.
