THIKTY-FIRST BIENNIAL REPORT 47 



upon regardless of weather or other conditions. The work of this 

 station during the biennium from June 30, 1928, to July 1, 1930, con- 

 sisted principally of fish cultural operations as the improvements and 

 repairs made during 1927 put the station in first class order. During 

 the next biennium the following improvements are necessary: new 

 understructure to Hatchery "A," new pipe lines, new fencing, a new 

 well, repairs to the power line and to the ice plant, totaling about 

 $3,350. 



During the years of 1928 and 1929, the general work and the output 

 of the station was fully up to the average. Several experiments in 

 feeding other foods than those usually fed at this hatchery were made 

 during the year, but the results are chiefly valuable in determining 

 what not to feed rather than what to feed. Reports of the experiments 

 have been made by Dr. Coleman and published by the division. 



Several improvements were made at the 'Mt. Shasta Hatchery. One 

 was the putting in of a small concrete dam in Spring Creek and run- 

 ning a pipe line of 16-inch pipe 975 feet to the diversion tank in the 

 hatchery grounds. This was a major improvement inasmuch as it did 

 away with the old flume and ditch, and in a great measure did away 

 with the moss and drift that worked into the ditch. The pipe was 

 buried underground and is out of the way and permanent. Another 

 improvement was the building of a new water tank to handle the water 

 from the pump for all domestic purposes within the hatchery grounds, 

 and for irrigating the gardens. The new tank is on a tower 36 feet 

 high with a base of concrete 18 by IS feet. The tank holds 4000 gallons 

 of water. The structure is covered with rustic and is attractive and 

 well built. Up to June 30, 1930, all the buildings have been painted 

 except the can house, lumber shed and several wood sheds. This puts 

 them in good repair. Also a new pipe line was laid from the water 

 tank to the residence and the residence refitted with new plumbing. 



CAMP CREEK EGG-COLLECTING STATION 



At the Camp Creek station a new cabin was built for use of the man 

 in charge during the spawn taking season. It is a plain, two-room 

 affair, but is warm and comfortable. This is the only improvement at 

 this station. Eggs collected during the biennium totaled 1,673,000. 



FALL CREEK HATCHERY 



At the Fall Creek Hatchery the results were good. During 1929, 

 4,005,000 Quinnat salmon eggs were received, 402,000 were lost and 

 3,603,000 planted. Rainbow trout eggs were received to the number 

 of 603,000 ; 23,000 eggs and fish were lost and 580,000 planted in the 

 tributaries of the Klamath River. This was almost 90 per cent effi- 

 cient for the salmon and a little over 96 per cent efficient for the trout. 

 Of course, the greater number of the trout eggs were received after 

 they were eyed and after all loss in hatching had been deducted. 



In addition to the trout and salmon planted in the tributaries of the 

 Klamath River from the Fall Creek Hatchery, there was a total of 

 439,000 Rainbow trout planted in tributaries of the Klamath River and 

 Scott River, the latter stream being also a tributary of the Klamath. 

 These fish were planted by the different associations of Yreka, Scott 

 Valley, and by the force of the Klamath National Forest.
