THIRTIETH BIENNIAL REPORT 51 



spring, rainbow and steelhead eggs were shipped to the hatchery and 

 all species thrived and made a fine growth. The fish grew so rapidly 

 that an early distribution of the surplus fish was necessary. Later 

 in the season six holding tanks were installed to hold the surplus fish 

 and to give them an opportunity to grow a size of 3^ or 4 inches 

 before planting. The total number of fish hatched at this station is 

 as follows : 



Eastern brook 70,600 Rainbow 246,700 



Loch Leven 41,000 Steelhead 251200 



Brown 85,750 Black spotted 95,200 



KAWEAH HATCHERY 



This hatchery was installed under a tent in 1919. Good results 

 have been obtained if the fish are planted early in the season. The 

 water from the East Fork of the Kaweah that is taken from the 

 discharge from the Southern California Edison Company's power 

 house produces fine, healthy fish until midsummer or whenever the 

 growth of algae and micro-organisms develop in the water and then 

 the fish do not thrive as well as they should. The water from the East 

 Fork is the best water to be found in all the Kaweah River system. 

 Some years the fish can be held all through the season until late in 

 the fall, but as a matter of getting best results, the fish should be 

 planted early in the season as they make a rapid growth during the 

 first three or four months of the spring and summer. During the 

 winter of 1927 and spring of 1928 a permanent hatchery with 50 

 troughs, and cottages for the help were built and are now in operation. 



KINGS RIVER EXPERIMENTAL STATION 



Early in March, 1928, plans were made to operate an experimental 

 hatchery on Kings River about 35 miles east of Fresno. This is a 

 centrally located site for the distribution of fish for the Upper San 

 Joaquin River and tributaries, Kings River and tributaries, and many 

 lakes in the high range from General Grant Park to West Fork of 

 the San Joaquin River. Considerable expense and labor were required 

 to construct a diverting dam in Kings River as the river does not have 

 a constant flow and the temporary dam had to be raised and made as 

 tight as possible to hold the water to a level where it would enter the 

 head of the intake for the hatchery. 



The water to date has proven good for hatchery purposes, and if 

 it continues to hold out during the remainder of the season, we will, 

 after one more season's operation, recommend the construction of a 

 permanent hatchery in that section. The Fresno County SportsnTen's 

 Club has assisted us as far as they could, and we also received many 

 favors from the San Joaquin Light and Power Corporation. 



KERN RIVER HATCHERY 



It was decided to carry on an experiment on Kern River to determine 

 whether the water from the main river, after passing through the power 

 house about seven miles above Kernville, was suitable for hatchery 

 purposes. The lumber of this new experimental station was on the 

 ground by the first of October, 1927. Mr. James Vogt, an experienced 

 fish culturist, was placed in charge. 



A frame was built, over which a canvas was spread to make the 

 hatchery. It was our plan to hatch eggs from the fall spawning fishes,
