ALASKA FISHERY AND FUR-SEAL INDUSTRIES, 1930 29 



freshet that had started to develop on the previous day began to brmg 

 down so much river weed and so many spent pink salmon that it was 

 necessary to remove the structure. The total count during the sea- 

 son consisted of 133,796 red salmon, 2,748 kings, 609,915 pinks, and 5,170 

 cohos. Except when young red salmon were coming downstream in 

 large numbers, traps and seines were operated in the river above the 

 weir to capture predatory trout, and some 45,000 of these fish were 

 destroyed. 



Operations at this weir were in charge of Henry B. Looff, \mder the 

 direction of Warden H. H. Hungerford. 



UGANIK RIVER 



A crew of workmen, together with supplies and lumber, were trans- 

 ported to the Uganik weir site on May 29, construction was begun 

 promptly, and by June 4 the weir was completed. No difficulty was 

 experienced in maintaining it throughout the season, as there were 

 no freshets. The first salmon passed through on June 5 and the last 

 on September 10, during which time the total escapement numbered 

 9,823 reds, 4,075 pinks, 1,978 cohos, and 2,714 chums. Large num- 

 bers of pinks and chums spawn in the river and sloughs below the weir. 

 Attention was given to the extermination of predatory trout while the 

 weir was in operation, resulting in the capture of 4,892 of these fish. 

 H. Olafson was in charge of the work at this place, under the direction 

 of Warden H. H. Hungerford. 



KAFLIA BAY 



On June 5 the watchman and supplies were landed at Kafiia Bay 

 and the work of establishing the weir in the salmon stream at the 

 head of the bay was begun. As usual at this time of year the creek 

 was rather high, but operations progressed satisfactorily and the 

 structure was completed on June 9. Salmon were first seen in the 

 bay on June 12, but none passed through the weir until June 25. 

 Counting was continued through August 27, at which time the run 

 had practically ceased. When the weir was removed on September 

 14 there were still a few salmon in the bay that would not enter the 

 stream. The total count of red salmon was 12,284. No pinks were 

 tallied, as most of them spawned below the weir. Young red-salmon 

 migrants were seen coming downstream in the latter part of June 

 and early in July. No great numbers of Dolly Varden trout were 

 observed ; and bears, although numerous, did not molest the weir. 

 As a result of an improvement to the salmon stream between the two 

 lakes during the latter part of August whereby the water was concen- 

 trated into one channel, the fish were enabled to ascend to the upper 

 lake more readily. Louis Thompson, under the direction of Warden 

 H. H. Hungerford, was in charge of the weir operations. 



ENGLISH BAY 



The escapement of salmon into the stream at the head of English 

 Bay was counted through a weir established at the same location as 

 in the previous year. This structure, 128 feet in length with two 

 counting gates, was ready for operation on May 23. Salmon began 

 to pass upstream on May 26 and the run continued through July 26, 

 during which time there were counted 18,858 reds. Jack Tansy was 

 in charge of the bureau's work at this place.
