keep up long enough for the crew to determine whether or not the 

 run of fish in this creek will justify further expense in an attempt to 

 collect eggs. 



FEATHER RIVER HATCHERY. 



After carrying on experimental work at this station in 40 troughs 

 under a tent, conditions were found favorable for establishing a per- 

 manent hatchery at this place. A lease for a period of 25 years was 

 procured from W. A. Adams. Plans were made and during the fall 

 of 1924 a hatchery containing 60 troughs was constructed and a cottage 

 for the help and a dwelling for the foreman built. This station is 

 located 4 miles from Clio on the Western Pacific Railroad and is only 

 a short distance from the Gold Lake region where there is a number of 

 fine mountain lakes that require stocking each season as well as the 

 streams tributary to the Middle Fork of the Feather River, streams 

 in Sierra Valley and surrounding country and the region along the 

 North Fork of the Yuba River. 



The hatchery has turned out a fine lot of fish. The only improve- 

 ments of any consequence at this station will be the laying of a two- 

 inch pipe line this fall from the settling tank to Mr. Adams' residenee 

 as the water from the hatchery flows into the domestic supply and a 

 supply of pure water must be furnished Mr. Adams' residence. 



From this hatchery 2,086,100 fish were planted during the biennial 

 period. 



BEAR LAKE HATCHERY. 



During 1925, operations were started during March by installing 

 the traps in the creeks tributary to Bear Lake. At the opening of Hie 

 season conditions did not appear to be favorable for a large take of 

 eggs, but as the season advanced, conditions improved and Bear Lake 

 furnished its usual supply of eggs. Of the 5,700,000 eggs collected, 

 2,700,000 of these were shipped to other streams, 2,000,000 hatched at 

 Bear Lake Hatchery and 1,000,000 at North Creek Hatchery. Reports 

 have been circulated for many years by the resort owners and others 

 that Bear Lake rainbow trout were being exterminated. These figures 

 show conclusively that the system under which we are working at 

 Bear Lake can not be improved. The lake is one of the best examples 

 of fishcultural success in this state or any other state, when the excessive 

 fishing of thousands from Los Angeles and other parts is taken into 

 consideration and the fact that there are thousands of predatory bass 

 in the lake and that all the tributary streams dry up before the middle 

 of July and that all the trout in Bear Lake are the result of artificial 

 propagation and distribution. 



The fish are held in the hatchery until the lowering temperature and 

 cold weather drives the large trout and bass into the deeper parts of 

 the lake, then the small fish from the hatchery are distributed in 

 the shallows along the shores where they have an abundance of food. By 

 the following spring, these young fish work into the deep water at a 

 time when the bass and large trout are coming toward the shores to 

 find breeding places. This system has been kept up for the last six or 

 eight years and the results can not be equalled or surpassed by any 

 system in the country. 



Improvements were made during the season of 1925 by moving the 

 cabin, remodeling and relining it and painting it on the interior and
