SITUK RIVER 



Construction of the weir on the Situk River was started on June 

 5 and completed on June 14. The first salmon were seen in the river 

 on June 12, and they began to pass through the weir on June 15.

ing was continued through July 19, when the work was suspended 

 because of an unusually heavy flood, which submerged the weir and 

 finally carried away about 60 feet of the structure. After the water 

 receded some of the material was salvaged, but not sufficient to 

 rebuild the weir. During the period of high water commercial 

 fishing was light and a large number of salmon escaped to the spawn- 

 ing grounds. The number of red salmon counted through the weir 

 was 191,377, and it is estimated that with the additional numbers 

 that ascended the stream after counting was discontinued the total 

 escapement for the season was not less than 300,000. In addition 

 to the red salmon there were counted 1,455 Idngs and 858 pinks. 

 Harry A. Pryde supervised operations at this weir.
