ESCAPEMENT TIMING Late ESCAPEMENT MAGNITUDE 



SPAWNING FACILITIES Good in the upper intertidal zone and lower part of the upstream area. Bottom 



composition becomes coarse upstream. 

 STREAM TEMPERATURES Warm range (Observed temperatures: 50* F. , 9/15/50; 47. 5* .F. , 9/27/50; 



47* F. , 9/21/51; 48° F. , 9/28/51; 47* -48* F. , 1952;' 51* F. . 9/7/53 SO* F. , 9/20/53). 

 VALLEY DESCRIPTION Glacial origin. The valley splits 2 miles upstream, and each branch contains 



a fork of the creek. The headwaters of the W. branch are near Barren Mountain, 3400' in height. 

 DRAINAGE 9 square miles (polar planimeter). Precipitation fed. Snowfi elds at the upper and E. side of 



the valley. A few small lakes to the S. 

 STREAM MOUTH IDENTIFICATION The stream enters the head of Sunny Cove. Grass flats are 



found on both the E. and W. sides of the mouth. 

 ANCHORAGE The cove affords good anchorage for small craft. 

 TRAILS AND SURVEY ROUTES The stream can be easily waded in its lower reaches, but due to 



boulders travel becomes difficult above the bedrock constriction. Fair game trails follow the N. bank. 

 AERIAL SURVEY NOTES Satisfactory for aerial survey. 

 GENERAL NOTES One of the better streams in Cholmondeley Sound. 



INTERTIDAL ZONE 



LENGTH 0.6 mile AVER AGE WI DTH/ DEP TH 35'-50'/15" 



GRADIENT AND VELOCITIES 



BOTTOM Medium gravel to coarse. 



LOW TIDE LOCATION 



HIGH TIDE LOCATION 



SCHOOLING AREAS There are no deep pools in the intertidal zone; fish tend to school off the mouth. 



SPAWNING AREAS Spawning takes place throughout the intertidal zone, but increases progressively 



upstream.

GRADIENT AND VELOCITIES Moderate 



BOTTOM Medium coarse gravel and boulders. 



MARKFR DISTANCE 



MARKER IDENTIFICATION 



BARRIERS A 6' falls 1 mile upstream could be a partial block at times of low water. 



TRIBUTARIES 1.5 miles upstream the stream forks. The right fork appears to be the larger of the two. 



SCHOOLING AREAS The large pool found in the bedrock constriction is the major schooling area. Other 



pools are also available. 

 SPAWNING AREAS The major part of the spawning takes place just above the high tide mark. Ad- 

 ditional spawning takes place throughout the upper reaches, but is confined by areas of bedrock.
