EFFECT OF CHANGED CONDITIONS ON FISH-CULTURAL WORK IN THE 



WASHINGTON FIELD 



It is evident that there has been no dechne in the runs of the 

 Tarioiis species of salmons in Puget Sound during the past few years. 

 In fact, it is very probable that, with the exception of the sockeye, 

 the runs have increased materially. However, conditions have so 

 ■changed as a result of lumbering and other industrial activities that 

 it can not be claimed that any of the stations in the Washington 

 :field are advantageously located at the present time for the propa- 

 gation of the chinook or the humpback salmon. 



At Baker Lake, where only the sockeye and the silver salmons 

 are propagated, most excellent results are apparent from the fish- 

 cultural operations. There is but little variation in the runs of either 

 species from year to year, and it would appear that the Puget Sound 

 sockeye run has thus far been maintained intact. It may therefore 

 be concluded that the adverse conditions complained of do not exist 

 to any great extent in the Baker Lake field. At every other point 

 in the State the work has been very seriously handicapped as a 

 result of deforestation, and if it is to be maintained at a high degree 

 of efficiency hereafter certain changes in methods will be necessary, 

 which will involve the expenditure of a larger amount of funds than 

 has been available in the past. 



At the Birdsview substation conditions are unsatisfactory. Grandy 

 Creek, on which it is located, and the lake which it drains at one 

 time provided excellent spawning areas for large numbers of salmon
