In 1922, there was a large escapement of pink salmon in the Karluk River, and 

 toward the end of their spawning season the carcasses of the fish that had finished 

 spawning and died began drifting down stream against the weir. Although a crew 

 was engaged in removing the dead fish from the face of the weir, it finally became impos- 

 sible to remove them as fast as they accumulated. As the fish piled up against the 

 weir, they obstructed the passage of water until there was danger of the weir collapsing 

 from the weight of the impounded water, and consequently, a number of pickets were 

 removed from the weir so as to allow the pink salmon carcasses to pass downstream. 

 The weir was not in use from August 21 to September 4, inclusive. It was replaced on 

 September 5, and the counting of fish was continued until the end of the season. 

 The counted escapement was 383,446, and it is estimated that the total escapement 

 that year was approximately 400,000 red salmon. 



In 1924, there was a tremendous run of pink salmon to the Karluk River and, as 

 in 1922, it was impossible to keep the weir in operation due to the dead pink salmon 

 drifting down against it. The weir was not replaced that season, so that it is necessary 

 to estimate the escapement from August 21 to the end of the season. The counted 

 and partially estimated escapement was 775,705. Gilbert and Rich (1927) estimated 

 that the total run that year was approximately 2,000,000 fish. Subtracting the catch 

 from this figure leaves about 1,100,000 as the number of red salmon in the escape- 

 ment. 



In 1934, it was again impossible to keep the weir in continuous operation due to 

 spawned-out pink salmon damming the weir and to extremely high water in the river 

 caused by the run-off of heavy fall rains. The weir was out from August 22 to Septem-
