THIRTIETH BIENNIAL REPORT 49 



DOMINGO SPRINGS HATCHERY 



This station is old and in a very bad state of decay. The usual num- 

 ber of fish have been raised in this hatchery and in spawning tanks. 

 As soon as possible this old hatchery should be abandoned and all the 

 operations carried on in a modern hatchery to take the place of the 

 Clear Creek and Domingo Springs hatcheries. These stations were 

 built during the war when the funds of the Commission were very much 

 depleted and were only temporary affairs to begin with. They should 

 be abandoned if possible, this fall and a temporary hatchery estab- 

 lished so that the output of fish can be handled in a temporary hatchery 

 until funds are available for the construction of the large centrally 

 located hatchery near Lake Almanor. 



We recommend the establishing of a hatchery in Sierra County on 

 one of the tributaries of the North Fork of the Feather River, as this 

 region is heavily fished and difficult to stock from the other hatcheries. 

 An experimental hatchery should be erected as soon as funds are 

 available for this purpose on some tributary stream of the North Fork 

 of the Yuba River. A hatchery in this location would not only 

 furnish fish for the North and Middle Fork of the Yuba River, but 

 for many lakes in this region that should be stocked annually. We 

 recommend that as soon as funds are available that a hatchery be 

 established in this district. 



WARNER CREEK TRAP STATION 



The usual number of eggs were collected at this station. A per- 

 manent rack should be installed in the river below the mouth of 

 Warner Creek so that all the spawning fish could be taken at one 



place. 



BUTT CREEK TRAP STATION 



The racks have been installed each season and considerable work 

 done to make this a good egg-collecting station, but owing to the fluc- 

 tuating head of water from the Lake Almanor tunnel, the results were 

 not satisfactory. In main Butt Creek the run of fish is not as great 

 as in former years as the fish attempt to follow the larger stream 

 coming from the tunnel and they are difficult to catch when the tunnel 

 is flowing a full head. The fish that ascend from Butt Lake are dimin- 

 ishing in numbers owing, no doubt, to the heavy fishing. 



OTHER EGG-COLLECTING STATIONS IN LASSEN PARK AND 



ALMANOR DISTRICT 



Our foreman inspected Butte Lake in Lassen National Park, as well 



as the intake of Manzanita Lake to ascertain if eggs could be collected 



from these lakes. No results were obtained there this spring, but it 



is possible to collect eggs from some of the fall spawning species this 



fall and winter. 



FEATHER RIVER HATCHERY 



This station, established during 1924 and first operated in 1925, has 

 been a success. There has been some minor improvements made such 

 as installing a pipe line to furnish a domestic supply for the residence 

 of W. A. Adams which was receiving the water directly from the 

 hatchery discharge. During the high water caused by the sudden 

 flooding of the streams in northern California during the latter part of
