76 FISH AND GAME COMMISSION 



Blacfc Rock Bearing Ponds, Inyo County. A long term lease on this 

 rearinfr pond site was obtained from the City of Los Angeles on May 20, 

 19-49. Improvements consisted of two four-room dwelling houses with 

 pressure system water supply and electric distribution system. Addi- 

 tional improvements, consisting mainly of a by-pass ditch which will 

 facilitate operations, will be undertaken early during the coming bien- 

 nium. 



Kern Hatchery, Kern County. Expansion and improvement of the 

 Kern Hatchery was carried on throughout nearly the entire two-year 

 period. The work was accomplished with Wildlife Conservation Board 

 funds under the direction of hatchery personnel. It consisted mainly of 

 building two new dwelling units, an extension to the hatchery building, 

 and a new feed room with refrigeration facilities, and improving the 

 water distribution system. 



Fillmore Hatchery, Ventura County. The water supply at this 

 hatchery failed entirely when the Santa Clara River went dry in Sep- 

 tember, 1948. In order to continue operations, it was necessary to drill 

 two wells — one in January, 1948, and the other in June, 1949. Other 

 improvements included four new houses, a garage and new hatchery 

 building. 



Hot Creek Hatchery, Mono County. This hatchery is not served by 

 a public utility, and electricity for lighting and food preparation was 

 until recently provided by several small butane-operated Kohler light- 

 ing plants. These units were discontinued in 1949 when a 30 k.v.a. Diesel 

 generator was installed. The hatchery building, containing 30 troughs 

 and formerly located in Alpine County, was moved to this location to 

 provide additional incubating and rearing facilities. 



Tosemite Hatchery, Mariposa County. Improvements at the 

 Yosemite Hatchery consisted of removing the old deteriorated wood floor 

 and replacing it with one of reinforced concrete. A new feed room and 

 six circular ponds were constructed, a new roof was placed on the 

 hatchery building, and improvements were made in the bachelor quarters. 



EXPERIMENTAL HATCHERIES 



In order to test the suitability of the water for fish rearing purposes 

 before a permanent installation is made at proposed hatchery sites, the 

 following experimental hatcheries were operated : 



Moccasin Creek, Tuolumne County. Experiment started December, 



1949. Indications are the water supply is satisfactory and a lease for use 

 of the property is being negotiated with the City of San Francisco, De- 

 partment of "Water and Power. Preliminary plans for a complete hatch- 

 ery unit are being prepared by the Division of Architecture. 



Willou' Creek, Lassen County. Fish rearing experiment at this sta- 

 tion got under way in June, 1949, and the experiment was discontinued 

 in December. 1949. The high alkalinity of the water at this location, 

 whern tpmperatures were favorable, made fish rearing activities impos- 

 sible. Thf site lias bnon pormanently abandoned. 



Cedar Creek, Mendocino County. Experiment started July, 1949, 

 but interrupted when heavy storms damaged the installation in January, 



1950. Sufficient experimenting was done before interruption, however, 

 to indicate that the water supply is suitable.
