42 FISH AND GAME COMMISSION. 



Tliese .small traps and effg-r-ollfftinfr stations have boen built because 

 we did not have the funds to concentrate our work. The initial expense 

 of installinfr the large stations was too great for the funds furnished 

 our department. Whenever funds are available for this improvement 

 wf)rk, the benefits to be derived from the establishment of permanent 

 traps, larger stations, and better equipment, will result in a larger 

 output of eggs for less cost per thousand after tlie initial expense of 

 establishing the station has been made. 



JOHNSVILLE EXPERIMENTAL HATCHERY. 



The Johnsville Experimental Hatchery was operated for tw^o seasons. 

 Owing to the great depth of snow and the inconvenience of getting 

 eggs to the station, in early spring, it was deemed advisable to select a 

 more favorable site. During the spring of 1922, when our men arrive 

 on the ground to begin operations, the snow was from 12 to 15 feet deep 

 on the level, with great masses on the slopes of the adjacent mountains, 

 threatening to come down in the shape of an avalanche at any time. 

 The work of shoveling out the snow and opening the station was an 

 arduous one and fraught with great dangers. As soon as the distribu- 

 tion of the fry was over in the fall of 1922, arrangements were made 

 to move the flume, tanks and other material to a new site located on 

 the property of ^Ir. W. A. Adams, on na.skell Creek, a tributary of 

 Sulphur Creek, near Clio, Plumas County, in a locality where the snow 

 does not fall so deep, and several miles nearer the railroad than the 

 site on Jami.son Creek. In the spring of 1923, after procuring a lease 

 from Mr. Adams for 25 years, a foundation was laid for the support 

 of 40 hatchery troughs. The water at this new site was thoroughly 

 tried out last sea.son and during the spring of 1924. It proved to be 

 of superior quality for the rearing of trout fry. We would recommend 

 that a permanent hatchery building and station be established on 

 this site, as it is the be.st site so far found anywhere in the immediate 

 vicinity of the Western Pacific Railroad in the Feather River region. 

 During the last two seasons 877,-380 rainbow and 857,000 steelhead 

 truut fry were distriliuted from this station in the lakes and streams 

 of the Feather River district. 



BEAR LAKE HATCHERY. 



The Bear Dake llutchery is situated in the San Bernadino Moun- 

 tains, in San Bernardino County, at Green Spot Springs near the 

 .shores of Bear Lake, and, as usual, has been successfully operated 

 during the la.st two seasons. During the season of 1922, 1,365,000 

 eggs were collected at the North Creek Egg-Collecting Station on Bear 

 Lake and transferred to this .station for hatching anct distribution. It 

 was also operated in the spring of 1923 with practicallj- the same suc- 

 cess as in the previous year and 1.100,000 eggs were collected. This 

 spring (1924 J, owing to the light snow fall and the lowering of the lake 

 by the water company, it was more difficult to procure the eggs than in 

 former seasons; but there appear to be as many trout in the lake as 

 at any time during the last five or six years. As mentioned in our 

 report of 1920-22, black bass were thought to have been introduced in 

 this lake, but we were somewhat in doubt at that time. The fact is 

 now well established that thousaiids of this species of fish are in the 

 waters of Bear Lake and are increasing annually as there is a great
