mon cannot ascend the stream except in the 2 hours before high water 

 and for 2 hours of ebb. This season, however, the water was un- 

 usually high and of a brownish color, which made it difficult to 

 observe the escapement accurately. JFrom June 2 to August 6, 

 inclusive, 20,820 red salmon were counted, and it was estimated that 

 the escapement included also from 7,000 to 8,000 salmon that were 

 not counted. In addition, a considerable number were observed 

 at the mouth of the stream when the watchman was removed on 

 August 7. 



KARLUK RIVER 



When the weir in Karluk River was being installed, from May 11 

 to May 17, the water was exceptionally low for the time of year. 

 King salmon started to pass upstream on May 24 and red salmon on 

 May 27, but there was no appreciable escapement until June 7, 

 after which the run was very heavy for about 3 weeks, with the result 

 that almost two-thirds of the season's escapement of red salmon 

 occurred in the month of June. The largest escapement for any one 

 day was on June 10, when 115,290 red salmon were tallied. When 

 counting was discontinued on October 6, the total escapement num- 

 bered 1,265,003 red salmon, 15,666 cohos, 6,882 Idngs, and 5,738 

 pinks. It was estimated that 30,000 salmon were still in the lagoon 

 at the time the weir was removed. 



The large escapement at the beginning of the season was accounted 

 for by the fact that storms wrecked apparatus and prevented fisliing 

 for a period during a heavy early run. As a result, the catch from 

 the Karluk run never did equal the escapement. The total com- 

 mercial catch of red salmon from the Karluk run was 1,028,730. 



Traps for the capture of predatory Dolly Varden trout were oper- 

 ated as usual in connection with the Karluk weir and caught 81,539 

 of these fish during the season. 



James O'Brien was in charge of the weir, under the direction of 

 Warden J. Steele Culbertson. 



KLAWxVK CREEK 



The weir in Klawak Creek, erected at the same site as in previous 

 years, was completed on June 2. Counting began on June 4 and 

 was continued through September 29, during which time the escape- 

 ment tallied was as follows: 33,544 red salmon, 572,271 pinks, 13,625 

 chums, and 2,578 cohos. It was estimated that half the pink salmon 

 and almost all the chums and cohos died at the foot of the falls above 

 the weir because low water made it impossible for salmon to ascend 

 the falls. Arrangements have been made whereby the Forest Service 

 will undertake to improve these falls, probably before the beginning 

 of the salmon run next season. L. M. Johnson was weir foreman at 

 the Klawak weir, under the supervision of Warden Donald S. Haley. 



LITTLE PORT WALTER 



A weir was again operated at Little Port Walter, primarily in con- 

 nection with the study of the pink-salmon runs in southeast Alaska. 

 From August 16 to September 9 there were counted 7,085 pink salmon, 

 53 chums, 8 cohos, and 3 reds. On September 10 no count was made
