26 U. S. BUREAU OF FISHERIES. 



placing the fingerlings in this inclosure all other fish that may have 

 collected therein are removed with seines and gill nets and the en- 

 trance is screened to prevent their return. The salmon may then 

 be given artificial food in addition to the natural food in the water, 

 and held until such time as it seems desirable to release them. 



During the winter months further trouble was experienced from 

 anchor ice, and it appears important that steps be taken to correct 

 this condition and thus avoid the threatened loss of valuable stock 

 each season. During extended periods of cold the water at the in- 

 take end of the pipe line falls to a level where the nipe does not 

 carry water to its full capacity. At such times anchor ice causes 

 trouble, and there is always danger of the line freezing completely. 

 Should this occur it would in all probability entail not only the loss 

 of all eggs or fish on hand but it would be liable also to seriously 

 damage the pipe line. As a corrective measure the superintendent 

 recommends certain alterations to the dam at the intake, including 

 an increase of its height to deepen the water at that point, and the 

 protection of the pipe against frost by covering it throughout its 

 entire length. 



BAKER LAKE (WASH.) STATION AND SUBSTATIONS. 

 [J. R. Russell, Superintendent.! 



Satisfactory results were achieved in the tish-cultural work in 

 this field during the fiscal year, the egg collections and output of 

 fish eggs and young fish from all points comparing favorably with 

 the work of past years, while the egg collections and output exceeded 

 those of the preceding year by a substantial margin. 



In this connection it should be taken into consideration that the 

 Quinault station, which for some years has been an auxiliary of 

 the Baker Lake station, is now being operated under the direction 

 of an indeipendent superintendent, and its output does not enter 

 into the total of the Washington group of stations. A review of 

 the year's work in the Quinault field is contained on page 29 of this 

 report. 



The Baker Lake field involves the work of six stations, all in 

 the State of Washington, with the headquarters of the superin- 

 tendent at Birdsview. Fish-cultural work in 1923 was addressed 

 to the five species of Pacific coast salmon and the stoelhead. Though 

 the humpback salmon does not figure in the year's egg collections, • 

 the si^ecies is represented in the output by upward of 1,500,000 of 

 advanced fry, these being the progeny of eggs collected in Alaska 

 waters by employees of the State of Washington, and of a smaller 

 shipment of eggs transferred from the bureau's Afognak station. 

 These transfers were made with the view of effecting, if possible, 

 the reestablishment of an annual run of humpback salmon in Puget 

 Sound waters. 



BAKER LAKE (WASH.) STATION. 



Though it has been found more convenient in recent years to 

 maintain executive headquarters at Birdsview, Baker Lake has 

 always been considered the main station of the Washington group. 

 It is the point at which the bureau first attempted fish-cultural work 

 in the State of Washington, and it has continued to be the most im-
