NOTES ON OPERATIONS 
COMMERCIAL SPECIES 
Pacific salmon.—The collection of approximately 5,000,000 chinook 
salmon eggs at the Battle Creek and Mill Creek, Calif., substations 
was somewhat below the normal take in this territory. At the former 
point a concrete settling tank for the water supply was constructed. 
At the latter location a new concrete structure was installed as a 
foundation for installing the racks used in trapping the fish. The 
station garage was enlarged and remodeled to provide office and shop 
space. 
The Baird, Calif., station was largely inactive and, at the end of the 
year, arrangements were being made for its abandonment and release 
to the Reclamation Service. A large dam contemplated in this area 
would effectively prevent the continuation of fish-cultural operations 
at this point. This marks the close of an establishment which was one 
of the earliest hatcheries operated in the United States. 
In the Columbia River territory, the Clackamas, Oreg., station 
and its auxiliaries collected a total of 49,146,000 eggs, some 15,000,000 
less than in 1936. Excellent collections were achieved with the 
chinook salmon at both the Big White Salmon and Little White 
Salmon stations. Flood conditions restricted the collection of steel- 
head trout eggs at the Butte Falls substation. Over 1,000,000 trout 
eggs were incubated at the Clackamas station, the fingerlings being 
released in various local waters. The surplus of chinook salmon 
eges at Little White Salmon substation necessitated planting some 
6,000,000 eyed eggs directly in local streams. Flooding of the station 
site by the pool from the Bonneville Dam will materially affect future 
operations here. Consequently, a deficiency appropriation of $60,000 
was made available to provide for the relocation of the station and 
transfer of the major portion of the work. A site at Tyee Springs on 
the Wind River near Carson, Wash., in the Columbia National 
Forest was selected. Construction activities were commenced in 
June. At Big White Salmon substation the run of chinook salmon 
was sufficient to have permitted the collection of additional eggs had 
trough space been available. As it was, several miilion eyed eggs 
were planted directly in suitable streams. 
In the Puget Sound territory, the Birdsview, Wash., station almost 
doubled the output of the previous year, handling 4 species of salmon 
and 3 varieties of trout. An excellent run of sockeye salmon has been
