ADF STAT. No. 

 56*46. 2' N. 134M7.2 1 W. E 40A 



EASTERN, FREDERICK SOUND, SECURITY BAY, extreme head of lagoon. 



MAJOR SPECIES Chum. OTHER SPECIES Pink, coho. 



ESCAPEMENT TIMING Middle to very late. 



SPAWNING FACILITIES Good. 



STREAM TEMPERATURES 



VALLEY DESCRIPTION Narrow valley with steep sides. Heavily wooded with many muskegs 

 scattered throughout. 



DRAINAGE 7. 8 square miles (polar plani meter). 



STREAM MOUTH IDENTIFICATION Stream flows across a wide grass flat and enters approx- 

 imately in the middle of the extreme head. 



ANCHORAGE Refer to stream #40. 



TRAILS AND SURVEY ROUTES The stream is difficult to survey during high water because the 

 many splits spread out the fish and dense wild currant bushes keep an observer away from the edge of 

 the stream. A fairly good game trail follows the left bank above the stream but it is difficult to 

 see the stream from it. 



AERIAL SURVEY NOTES Fair for aerial survey. Enter valley on right side and fly to head of the 

 valley. Salmon in large numbers move to the extreme head of this stream. 



INTERTIDAL ZONE 



LENGTH 0.2 mile. AVERAGE WIDTH/DEPTH 30718". 



GRADIENT AND VELOCITIES Slow. 



BOTTOM Clean gravel on riffles. Clay exposed in deepest holes. 



LOW TIDE LOCATION Confluence with lagoon. 



HIGH TIDE LOCATION Beginning of timber at edge of grass flats. 



SCHOOLING AREAS Primarily in the lagoon off the mouth and throughout the deep water areas of 



the intertidal area. 

 SPAWNING AREAS Good spawning throughout. 



GENERAL NOTES A few pinks that use this system seem to prefer the fine intertidal gravel. 



UPSTREAM 



LENGTH ACCESSIBLE 2 miles. AVER AGE WIDTH/ DEPTH 35'/10". 



GRADIENT AND VELOCITIES Moderate to slow. 



BOTTOM Gravel. Considerable brown algae on gravel on many riffles. 



MARKER DISTANCE No marker. 



MARKER IDENTIFICATION 



BARRIERS Log jams are a problem at low water levels only. 



TRIBUTARIES None. 



SCHOOLING AREAS Many pools throughout the length. 



SPAWNING AREAS Good. 



GENERAL NOTES When surveying by foot, stay along streambed as there are extensive beaver ponds 

 along both sides of the stream back from the streambanks. The pinks enter as a middle run, but the 

 major species, chum, enter late and continue along with coho into November. The stream has 

 supported "fall fisheries" in the past. Extensively used for subsistence by Kake people.
