THIRTY-FIRST BIENNIAL REPORT 57 



results that can be obtained by stream closing and proper planting of 

 healthy fish. 



There are some repairs necessary to the tanks, dams, etc., that should 

 be made in the near future. 



Total eggs collected from this station for 1928, 1929 and 1930, 

 13,134,000. 



MT. WHITNEY HATCHERY 



The only major improvement at Mt. Whitney Hatchery during the 

 last two years was the installation of the pipe line to furnish residents 

 below the hatchery their domestic water supply. Besides stopping all 

 agitation among the water users, this improvement will allow us to 

 install additional ponds for holding brood fish. We have been unable 

 to build up a supply of brood fish Math only one pond. We recom- 

 mend that two or three additional ponds for such purposes be built. 

 The cost would be approximately $3,000. 



Another improvement that would greatly help the conditions among 

 the men at the Mt. Whitney Hatchery is to have two cottages built on 

 the hatchery grounds. At present the men are sleeping and cooking in 

 different parts of the north wing of the hatchery, wherever room can 

 be made for them. About $4,000 will be necessary for the construction 

 of cottages. 



During the last two years approximately one hundred barren lakes 

 have been stocked in Inyo, Mono and Alpine counties from Mt. Whitney 

 and Fern Creek hatcheries. These have all shown good results. A 

 good many of these lakes have been stocked with golden trout. 



COTTONWOOD LAKE STATION 



In closing the Middle (lottonwood Lake to fishing, we greatly 

 improved our egg take at that station, and we would recommend that 

 several lakes be closed for our spawning operations. This will guar- 

 antee us a constant supply of eggs for our hatcheries. If other lakes 

 in this district were closed for different species of trout, all the eggs 

 for this district could be collected without having them shipped in from 

 the outside. 



GULL LAKE EGG-COLLECTING STATION 



We recommend that one-third or a portion o^f Gull Lake, in Mono 

 County, be closed to fishing. We have built Gull Lake up for egg- 

 collecting purposes by heavy stocking, but the fishermen catch the 

 majority of the fish before they attain spawning age. The season 

 should close on October 1st, to give the Eastern Brook trout a chance 

 to approach the shore where they can be seined and the eggs collected. 



Total eggs collected at this station during 1928 and 1929, 1,445,000. 



WALKER RIVER STATION 



Last spring we operated on West Walker River and found a good 

 run of fish — Rainbow and black spotted — ascending the stream to 

 spawn. The river was racked off, but owing to the high water at the 

 time the fish were running was unable to handle the stream. We recom- 

 mend that a permanent dam be built in this stream so that we can 

 handle the water during the run-off. To install an egg-collecting station 

 on this river would cost approximately $6,000.
