HATCHERY ADDITIONS AND BETTERMENTS 



Darrah Springs Hatchery, Shasta County. Experimental opera- 

 tions started July, 1949. Operations have been very satisfactory and five 

 earth-fill ponds constructed. Plans liave been made to pnrchasc the 

 hatchery site presently under lease and it is expected tliis location will 

 eventually be developed into one of the larg:est hatclieries in the State. 

 A constant water supply of approximately 30 c.f.s. at temperatures 

 ranging from 56 degrees to 60 degrees makes this site especially adapt- 

 able to the production of eggs and the rearing of catchablc-si/.e trout. 



Moorehouse Spring Hatchery, Tulare County. Experimental oper- 

 ations started 1947. A spring-fed water supply of approximately 60 

 degrees, while limited in volume, makes this station adajttable to the 

 rearing of trout. During the biennium two dwelling hou.ses, a four-stall 

 garage and a refrigerated food preparation room were built aiul other 

 minor improvements were made. 



Mojave River Hatchery, San Bernardino County. Experimental 

 operations, consisting of four rearing ponds, were started at this location 

 in June, 1947. The number of ponds was increased to 20. This work 

 was started by the contractor in May, 1950, and nearly completed at the 

 end of the biennium. Two new electrically operated pumps with auxiliary 

 gasoline engines were installed. 



3It. Shasta Hatchery, Shasta County. Rehabilitation of this hatch- 

 ery, which has been in constant operation since iHhH. was undertaken 

 during the latter part of the period covered by this report. This con- 

 sisted of removing nearly the entire outmoded pond system and installin^j 

 16 earth-fill racewav tvpe ponds. A contriK-t covering this pond const ruc- 

 tion in the amount of $68,402 was let on -Inly IS. 1950. Additional plans 

 for installing a new feed room and a hatchery bnilding with 120 troiigh.s 

 have been completed. Funds for this project were provided l.y ili.- WiM- 

 life Conservation Board. 



Mt. Whitney Hatchery, Inyo Cunly. .Vdditions to this hat<-lieiy 

 consisted of a new feed room with 60,000-i)oHiid capacity refrijjorator.
