TWENTY-EIGHTH BIENNIAL REPORT. 4X 



CLEAR CREEK HATCHERY. 



The Clear Creek Hatchery and egg-eolleetiiig: station has been snccess- 

 fully operated dviring the last two years. During the spring of 1922 

 we had the usual run of fish in Clear Creek, a tributary of the Hamil- 

 ton branch of the Feather River, from which the fish come that furnish 

 the eggs for this station. There was also a good run in 1923. There was 

 a larger run of fish than usual in the Hamilton branch of the Feather 

 Eiver in the spring of 1924; but. owing to the low condition of the 

 water in the Hamilton branch caused by the drought, and, also, by the 

 diversion of the water by the Red River Lumber Company to their 

 power plant, we had considerable difficulty in collecting eggs. How- 

 ever, 3,100.000 eggs were collected this sprinsr (1924). During 1922, 

 1.683.000 eggs were collected and in 1923, 2,100,000 were collected, 

 making a total for this station for the biennial period of 1922-23 of 

 3,783,000. A two-room cabin was built for the crew in the fall of 1923 

 and some additional troughs installed in the hatchery. Improvements 

 were made to the traps and fish holding tanks. This hatchery should be 

 enlarged as soon a.s funds are available as it is necessarv' to hatch a 

 greater number of eggs to maintain the supply of fish in the streams 

 and lakes of this region. 



WARNER CREEK TRAP. 



Owing to the exceedingly high water in Warner Creek, this station 

 was not operated in the spring of 1923. During 1922 1.905,000 eggs 

 were collected; and. owing to the low condition of the water in 1924, it 

 was successfully operated and 2,892,000 eggs were collected. Improve- 

 ments were made in the fall of 1923 at this station by repairing the 

 traps and flume and adding sixteen feet to the fish holding tank. A 

 small eyeing station of six or eight troughs should be installed at 

 Warner Creek so as to hold the egg's until they are advanced far enough 

 to ship to other stations. It is quite dilficult in the early spring, when 

 the snow is deep in this section, to transport the eggs from this station 

 to Domingo Springs station where they are hatched. The mouth of 

 the creek, where it has its confluence with Rice Creek, should be widened 

 and a permanent crib installed so the racks can be moved to this point, 

 a more suitable place than the place where they now are. 



DOMINGO SPRINGS STATION. 



This station has been in operation the last two years with its usual 

 success. In the fall of 1923 a new flume was built to furnish the water 

 supply for the hatchery and tbe fish-holdinsr tank. As soon as funds 

 are available, this station should also be enlarged .so as to increase its 

 capacity to at least double what it is at present as more fry are needed 

 each year to supply the lakes and streams in all sections of the state 

 wherever hatcheries are located. To properly handle tlie situation in 

 this section, a permanent rack, or rolling dain, should be placed acro.ss 

 the north fork of the river below the junction of Rice Creek and War- 

 ner Creek and a permanent station estaldished. Tliis Avould cost 

 several thousand dollars, but the results that would be obtained would 

 justify the expenditure as the work could all be concentrated at the 

 one station and a great many more fish caught, and eggs procured that 

 are now deposited on the spawning beds below Warner Creek and 

 between the mouth of Warner Creek and Domingo Springs station.
