ALMANOR HATCHERY. 



This hatcher}^, located near tlie outlet of Lake .Almanor was abandoned 

 during the fall of 1920. During the latter part of each season there 

 was not sufficient water to operate the station successfully, as the Great 

 Western Power Company uses so much of it for the domestic supply at 

 their cottages, thus depriving the hatchery of its supply. The building 

 was torn down and the troughs moved to Domingo Springs Station. The 

 lumber was also used in making improvements at Domingo Springs. 



DOMINGO SPRINGS STATION. 



This egg-collecting station and hatchery has been successfully operated 

 during the last two seasons. The rack across Rice Creek where the trap 

 is situated was damaged by high water during the spring of 1920. New 

 cribs were built and timbers for the main chord replaced and the rack 

 and traps generally overhauled. This station furnished us with 

 3,500,000 rainbow trout eggs during 1920-1921. 



WARNER CREEK TRAP. 



During the fall of 1920, a rack and trap were placed in the mouth of 

 Warner Creek. Warner Creek rises in Warm Spring Valley on the basal 

 slopes of Mount Lassen and flows southerly to its junction with Rice 

 Creek, the two streams forming the North Fork of Feather River, trib- 

 utary to Lake Almanor. During the spring, the water in Warner Creek 

 rises to a great height in the narrow canyon at its mouth. A large num- 

 ber of rainbow trout ascend this stream each spring. A permit was 

 obtained from the Forest Service to erect a cabin and place a rack and 

 trap in this stream. The high water made it difficult to operate at this 

 place, but our crews managed to procure 896,000 eggs during the 

 springs of 1921-1922. This station is located about five miles below 

 Domingo Springs Station. There should be one large rack constructed 

 across the North Fork of Feather River below the junction of Warner 

 Creek and Rice Creek and all the work concentrated at one place. This 

 will insure a large take of eggs each season and at the same time be 

 more economical. 



A lease for a hatchery site and egg-collecting station below the junc- 

 tion of Warner Creek and Rice Creek was procured from Curtis, Col- 

 lins, and Holbrook Company three years ago, but as we have not had 

 sufficient funds to construct the station, the work has been deferred 

 until the financial condition of our Commission would permit the work 

 being done. 



CLEAR CREEK HATCHERY. 



Clear Creek Hatchery and Egg-Collecting Station has been operated 

 as in former seasons. The run of fish from Lake Almanor entering Clear 

 Creek, a tributary of the Hamilton branch of the Feather River which 

 has its mouth in Lake Almanor, still maintains a good run of rainbow 

 trout despite the heavy fishing in the lake. Two million eggs were col- 

 lected at this station and 600,000 fry hatched at Clear Creek Hatchery. 

 The remainder were shipped to other stations. The traps and tanks were 

 enlarged and plans are being made to enlarge the holding tanks and to
