are 36 feet long, 8 feet 10 inches wide, and 5 feet deep, with walls 8 

 inches in thickness, and concrete foundation. 



A new flume, 250 feet long and 1-4 inches l)y 16 inches, was built 

 from the main supply ditch to hatcheries C and D. A number of the 

 ponds were relined with new plank and inlets and outlets to six of 

 the ponds were renewed. The ditch was enlarged west of the hatchery 

 ground to make an additional fry pond. New screens were installed 

 in all the hatchery troughs during the period covered by this report. 

 Drain pipes were placed under the roads in front of Hatchery A. A 

 new drain from Hatchery A to Pond No. 8 was installed. A new room 

 was built in the attic of the foreman's dwelling and other improve- 

 ments to keep the station in repair, l)ut just enough repair work was 

 done to prevent damage to the system of ponds and hatcheries so that 

 they could be operated. 



A number of improvements recommended to be constructed during 

 the coming biennial period are as follows : 



A new food preparation room, refrigerating plant and cold storage 

 rooms for keeping the fish food in good condition. A new building 

 should be constructed to be used as a storage room for fish cans and a 

 paint room. This should have a steam boiler installed for steaming 

 the cans, keeping them sanitary, something essential to keep the fish 

 in good condition. 



One new corrugated drain pipe to take water from Hatchery A. One 

 galvanized drain to cross the road under the lane in front of Hatchery 

 A, as the present culvert is in l)ad condition. 



All the ponds, except two, should l)e relined with planking, in whole 

 or in part. The plankiiig on these old ponds and walls should be 

 renewed, as they have been in use from 15 to 25 years. The superin- 

 tendent's and foreman's cottages should be repaired; a concrete bridge 

 constructed over the inlet of pond system on the road leading across 

 the hatchery ground to barns and garage. These are only a few of 

 the many improvements that are necessary to keep this important sta- 

 tion in repair. 



An additional water supply should be furnished to this station if 

 it is to be operated to its fullest capacity, as the drought has affected 

 it several times in the past ; also, the water owners are using water 

 from Spring Creek, from wliich this station receives its water supply, 

 and take their usnal amount regardless of the seasonal conditions, 

 and the hatchery suffei's accordingly. When the irrigation period was 

 on this spring, the farmers diverted so inueh water that there were 

 tiiiu's when the fish in the hatchery, as well as in the ponds, were in 

 danger of suffering materially, if not perishing, for want of sufficient 

 water supply. A meeting was called at Sisson on May 20, 1924, and 

 the water users diverting water above JMount Shasta Hatchery agreed 

 to turn back from tlieir ditches sufficieni water to mainfjiin the hatcherv' 

 until seasonal conditions would l)ring about a larger flow in Spring 

 Creek. This we greatly appreciated, as it prevented serious loss and 

 damage to the fish at IMount Shasta Hatchery. 



The auxiliary stations under tlie supervisiou of Blount Shasta 

 Hatchery were oi)erate(l (luring the last biennial pei'iod to their fullest 

 capacity. These stations jire Fall (h-eek Hatchery, Klamathon egg- 

 collecting station, H()rnl)rook egg-collect in a' station, Bogus Creek egg- 

 col Icct in tr station, and Camp Creek egg-collecting station.
