14 U. S. BUREAU OP FISHERIES 



July 28, but the numbers were negligible until August 6, after which 

 they increased gradually until August 26, when 20,103 of this species 

 passed through the weir. Before the end of the month the daily 

 escapement dropped to about one-fifth of this number and continued 

 fairly stead}^ thereafter for nearly 4 weeks, except on September 19 

 and 20, when the daily tally showed 48,178 and 42,645 pink salmon, 

 respectively. When operation of the weir was discontinued at the 

 close of October 10, the total count numbered 425,180 pink salmon, 

 32,924 chums, 20,028 reds, and 6,955 cohos. It was estimated that 

 there were then in the harbor at the mouth of the river 15,000 salmon, 

 consisting mainly of pinks and chums in about equal numbers. Lloyd 

 M. Johnson was the weir foreman, under the supervision of Warden 

 Alexander P. Romine. 



LITTLE PORT WALTER 



Through the weir in the stream at the head of Little Port Walter, 

 which is maintained primarily to supply information in connection 

 with biological studies of pink salmon in southeast Alaska, 6,073 pink 

 salmon were counted from August 12 to September 21, inclusive. 

 About 250 pink salmon were in the stream below the weir when the 

 structure was removed on September 22. S. J. Hutchinson carried 

 on the weir operations at this place, under the direction of Dr. 

 Frederick A. Davidson. 



SITUK RIVER 



Counting of salmon at the Situk River weir began on June 7 and was 

 discontinued on August 10, when high water submerged the structure 

 and washed it out at one end. The total count was 163,303 reds, 

 20,593 pinks, 632 kings, and 34 cohos. It was estimated that with 

 the additional numbers passing upstream after the weir was removed 

 the total escapement of red salmon for the season was at least 175,000. 

 An extension of 24 hours to the weeldy closed period was made on 

 July 15 to assure the required escapement of at least 50 percent of the 

 run. The reported commercial catch of red salmon for the season 

 from the Situk River run was 151,768. Weir operations were under 

 the supervision of Assistant Agent W. W. Kinsey. 



ALITAK BAY 



The cannery station weir on Olga Bay in the Alitak Bay region was 

 comi^leted on May 14, but it was not until May 27 that the first 

 salmon passed upstream. Throughout the season the escapement was 

 very irregular, which may be attributed, in part at least, to the fact 

 that the stream was often very low. The highest count of red salmon 

 for any one day was 17,799 on August 10, and the total count of reds 

 for the week ending on that date was 25,550. The next highest 

 weekly escapement was 14,656 red salmon in the week ending Sep- 

 tember 7. For the entire season the weir count numbered 85,025 

 red salmon, 5,662 cohos, and 640 pinks. There was still a large 

 number of fish, chiefly cohos, in the lagoon at the time the weir was 

 removed on September 12. 



As in the previous year, no weir was maintained in the upper station 

 stream, which harbors the largest run in the Olga Bay region. It 

 was estimated that the escapement of red salmon there was 400,000. 

 The run was light until the latter part of July, after which it increased 

 and continued good until about the middle of September,
