ALASKA FISHERY AND FUR-SEAL INDUSTRIES, 1930 25 



completod in one week. Counting ])egan on June 21 with the ascent 

 of the first red sahnon. The coinit of pinks started on Jidy 29, but 

 no a|)prer.iabh' number of this species jjassed upstrenjn until August 

 13. The run held fairly steady until September 3, after which low 

 water in the creek hindered or completely stopped the ascent of 

 salmon for 11 days. Heavy rains raised the stream on September 14 

 and during the week following more than 1,000,000 salmon were tal- 

 lied. The final count was made on September 24, when the total 

 escapement for the season numbered 1,412,912 pink salmon, 15,615 

 chums, 13,240 cohos, and 7,044 reds. Ernest Petry was in charge 

 of counting operations, under direct supervision of Warden C. L. 

 Olson. 



OLIVE COVE 



The Olive Cove weir was established at approximately the same 

 location as in 1929. On June 6 the clearing of the trail and trans- 

 porting of material from the head of the bay to the weir site was 

 begun. Actual installation of the weir was started a week later and 

 completed on June 25. During the same period a special inclosure, 

 15 by 32 feet, to hold approximately 800 salmon for scientific study 

 during the season was built, and also a camp for use of the scientist 

 conducting the investigation. 



A few salmon were seen in the river below the falls on July 2 and 

 considerably greater numbers within the next few days, but they did 

 not begin to pass through the weir until July 13. The peak of the 

 run occurred during the last week of July, after which there was a 

 gradual decline until August 16, when counting was discontinued. 

 The total number of salmon counted consisted of 134,073 pinks, 38 

 cohos, and 172 chums. A conservative estimate of the number below 

 the falls at the time the weir was closed, together with the count for 

 the season, places the total escapement of pink salmon at not less 

 than 150,000. Walter Campen, under the direction of Assistant 

 Agent S. A. Baker, was in charge of operations at this weir. 



STANEY CREEK 



Installation of the weir at Staney Creek was begun on June 21 and 

 finished four days later. The stream at the weir site, 1 mile above 

 the mouth, is 180 feet wide, with an average depth of 2 feet. The 

 first salmon appeared at the weir on July 7, when 2 chums passed 

 upstream. Pink salmon began to ascend on July 22, the numbers 

 increasing very slowly until the 8th of August, after which there was 

 a steady run of fairly good volume for some two weeks. The largest 

 escapement of pink salmon for any one clay was on September 14, 

 when 65,310 were counted. Twice during the season heavy rains 

 caused the water to rise 18 inches over the top of the weir, and the 

 structure was finally carried out on October 1, when large logs and 

 trees were swept against it by the current. The total count for the 

 season consisted of 366,881 pink salmon, 20,398 cohos, and 42,967 

 chums. The work was in charge of J. H. Hall, under the supervision 

 of Warden C. L. Olson. 



WHALE PASSAGE 



A weir for counting the escapement of spawning salmon was again 

 maintained in AVhale Passage Creek, construction being started on 

 June 18 and completed on June 30. The first count was made on
