64 FISH AND (!AMK COMMISSION 



Xortli Fork of tin- FralluT Ki\rr. Tho spawn iiipr fish ascend the river 

 from Lake AIniaiioi- and cnlcr Warner ('r<'('k Avlicrc a larjrc nnmber of 

 Haiidtow o<i<;s were collci-lcd each season Tor the hist ten years. 'Plie run 

 of fish in all the tril)utaries of Jjak(^ Alinanor are, except Hamilton 

 P>raneli, as larfjre if not larcer than they were ten years n^o, despite the 

 heavy fisliin<; in Lake Almanor. Tlif total number of ejrf^s collected 

 from Warner Creek Statioii diiiiu'.r the last two seasons was 2,965,000, 



IV1UD CREEK EGG-COLLECTING STATION 



Tliis is a eoiiiparatively new station. Plans were made several times 

 in the past to install traps in this creek, hut ilic bed of the stream near 

 the mouth where it empties into Lake Almanor made it a difficult 

 problem until the sui-faee of Lake Almanor was raised, backing the 

 water to a higher level where a tra]) could be installed with safety. 

 This AA-^s successfully done two years ap:o. The total number of eggs 

 taken from this creek duriiiir the last two seasons was 1,075,000. 



YOSEMITE HATCHERY 



Successful work has been carried on at this hatchery since it was first 

 operated in the spring of 1927. Owing to conditions of the water, con- 

 siderable skill and care must be exercised by those in charge of the 

 work to get a maximum of results, but during the three seasons that 

 this station has been operated the results have l)een equal to the average 

 of all fish cultural stations in this state. We have propagated all 

 species of trout that are handled at the California hatcheries, as well as 

 a successful hatch of grayling eggs that were received from ]Montana. 

 The grayling eggs were shipped to the Yosemite Hatchery as well as to 

 the Tahoe Hatchery as an experiment to determine whether this species 

 can be successfully introduced into the waters of the high Sierra. 

 Attempts were made several years ago to introduce the grayling and 

 after several years of planting in favorable places no results were 

 obtained except in the ponds at the Mt. Shasta Hatchery. There several 

 thousand were raised to adult size, but the fingerlings and fry planted 

 in a number of streams and lakes were not seen again. Thej^ were 

 planted in waters that were not inhabited by other species of fishes as 

 well as in streams and lakes in which other species were found, but the 

 work failed to produce any results. We are hoping that this attempt 

 now being made at Tahoe and Yosemite hatcheries will be more suc- 

 cessful. 



Four rearing tanks have been added to the hatchery, grounds 

 improved and show ponds constructed during the past two years. A 

 meat and ice house will be constructed in the near future. A woodshed 

 and garage should be constructed at this hatchery. 



Following is a list of the fish distributed from the Yosemite Hatchery 

 during the seasons of 1928 and 1929 : 



440,700 Rainbow trout. 

 276,000 Loch Leven trout. 

 743,500 Steelhead trout. 

 203,200 Eastern Brook trout. 

 48,000 German Brown trout. 

 203,500 Black Spotted trout.
