38 FISH AND GAME COMMISSION. 



To insure tho safety of those traps dnriiifr seasons of heavy snow fall 

 when the melting snow causes flood conditions, concrete toe walls 

 should be constructed across the beds of these creeks, as well as con- 

 crete cribs placed in tlie streams to support the chords in the trap 

 frame. Tliis would insure us against any accidents which might be 

 caused by tlond waters in these creeks. 



UPPER TRUCKEE RIVER EGG-COLLECTING STATION. 



Tlie same eondiTioii jtrevails at the Upper Truckee River egg-collect- 

 ing station, and this station should be improved by a concrete abut- 

 ment on the side of the creek, as well as cribs and concrete toe walls or 

 aprons across the creek bed to prevent the traps from M'^ashing out 

 when streams again are normal, thus insuring the safety of all of 

 these traps. There were collected from this station 200,000 eggs during 

 1922. 



UKIAH HATCHERY. 



During the season of 1922 this hatchery was operated to its capacity, 

 but no improvements were made until the winter of 1922-23 as it was 

 necessan- to procure a new lease on this property from the town of 

 Ukiah. After procuring a lease for a period of five years from the 

 trustees of the town of Ukiah, beginning January 21, 1924, we made 

 repairs to this hatchery. This property was received from the North- 

 western Pacific Railroad Company many years ago when the railroad 

 company, in conjunction with the Fish and Game Commission, oper- 

 ated this hatchery for a number of years. Since the railroad company 

 ceased to operate this hatchery it has been operated by the Fish and 

 Game Commission under a lease from the town of Ukiah. No great 

 amount of money was expended on the repairs — .just enough to keep 

 the station in good condition. A new pipe line was installed to fur- 

 nish the water supply, as the amount of water at this station is limited 

 and any leakage from the old flume caused considerable damage to the 

 hatchery operations. During the spring of 1924, owing to the shortage 

 of water, a limited number of eggs had to be placed in this station, 

 and. as the drought prevailed through the sections that are u.sually 

 planted from this hatcheiy, some fry were hatched to supply all of 

 the streams in this section and an early distribution made. The 

 following number of frv were hatched during the last two years: In 

 1922, 962,500: and in 1923, 1.015,000. 



SNOW MOUNTAIN STATION. 



At this Station 1,594,000 eggs were collected in 1922 and 2,857,960 

 in 1923, and the resulting fry hatched in the Ukiah hatchery and other 

 stations of the Commission. Owing to the shortage of water in the 

 South Eel River during the season of 1924, the station was not 

 operated. Preparations were made during the winter to operate this 

 station the same as in former years, but the Gravelly Valley Dam held 

 back the water in tbe South Eel River, thus preventing a sufficient 

 flow of water to reach the Cape Horn Dam, at which place the Snow 

 Mountain egg-collecting station is located. There was not sufficient 

 water passing this dam at any time to enable the steelhead trout to 

 ascend this branch of the Eel River so the eggs could be collected. The 

 drought that prevailed throughout this region was probably greater
