EASTERN, FREDERICK SOUND, KEKU STRAIT, KADAK BAY, Head. 



MAJOR SPECIES Pink. OTHER SPECIES Chum, coho, trout, steelhead. 



ESCAPEMENT TIMING Middle. 



SPAWNING FACILITIES Excellent spawning riffles in first half mile. Intertidal zone affords only 

 limited spawning facilities. 



STREAM TEMPERATURES Warm range. Observed temperature: 56° F. , 9/7/53. 



VALLEY DESCRIPTION Broad, heavily timbered valley. Flat muskeg valley. 



DRAINAGE 51. 5 square miles (polar planimeter). 



STREAM MOUTH IDENTIFICATION Enters Kodak Bay through an extensive mudflat in the SW. 

 corner of the bay . 



ANCHORAGE Anchorage is available at the mouth of Kadak Bay in 8 fathoms of water. 



TRAILS AND SURVEY ROUTES At normal water levels, large bars are exposed and the stream is 

 easy to travel. 



AERIAL SURVEY NOTES The lower half mile of the stream is subject to extreme flooding as evi- 

 denced by large, high bars, deep holes, and huge windfalls piled up on the bars. Discolored water 

 usually makes surveying difficult. 



INTERTIDAL ZONE 



LENGTH At low tide 1. 7 miles. AVERAGE WIDTH/DEPTH 30'/10". 



GRADIENT AND VELOCITIES Gentle. 



BOTTOM Gravel, silt, and algae. 



LOW TIDE LOCATION 



HIGH TIDE LOCATION 



SCHOOLING AREAS Schooling is done primarily off the mouth of the stream due to fairly shallow 



intertidal area. 

 SPAWNING AREAS The stream affords limited spawning facilities. The upper 0. 1 mile is quiet and 



deep with much silt and algae. Below this, there is about a half mile of occasional short spawning 



riffles with medium to large angular gravel and considerable algae. 

 GENERAL NOTES 



UPSTREAM 



LENGTH ACCESSIBLE Estimated 7 miles. AVERAGE WIDTH/DEPTH 30710". 



GRADIENT AND VELOCITIES Gentle. 



BOTTOM Gravel, sand, and silt; some bedrock and boulders. 



MARKER DISTANCE 



MARKER IDENTIFICATION 



BARRIERS Several large windfalls and large gravel bars. 



TRIBUTARIES This is a very large stream entering the bay in 2 branches. About 2.5 miles from the 



high tidemark, there is a fairly large tributary to the main stream. 

 SCHOOLING AREAS Some deep pools in first half mile. 



SPAWNING AREAS Excellent riffles of medium to coarse, angular gravel in first half mile. Then a 

 half mile of shallow, quiet water with fine gravel, sand, and silt. Excellent spawning riffles above 

 this; medium, angular gravel on riffles and occasional pools. 



GENERAL NOTES This is one of the key streams of this area and can be considered a heavy producer. 

 A Forest Service cabin is at the head of the tidewater on the S. bank. This system was mapped and 

 surveyed in 1962 by ADFGG Biological Research Division.
