from Little White Salmon (Wash.) station, 100,000 blackspotted 
trout from Montana Fish and Game Commission, 25,000 black- 
spotted trout from Yellowstone Park, and 197,000 brook trout and 
96,000 rainbow trout from Springville (Utah) station. 
UPPER CLACKAMAS (OREG.) SUBSTATION. 
The spring run of chinook salmon in the Clackamas River was the 
largest for a number of years, and egg collections of that species at 
the Upper Clackamas substation exceeded the previous season’s 
record collection by nearly 800,000. Racks were installed early in 
July and fishing operations continued until September 16, when 
high water permitted the escape of all remaining fish, probably two- 
thirds of all the fish intercepted by the racks getting away at this 
time. ‘There has been a most decided improvement in the annual run 
of spring chinooks in this stream, and the station, though small, is 
of importance to the fisheries of the Clackamas River. Because of 
its exceptionally attractive and convenient location and its well-kept 
condition it is a point much favored by visitors. Unfortunately, 
the Clackamas River is difficult to protect against the poacher, and 
illegal fishing is prevalent. 
LITTLE WHITE SALMON AND BIG WHITE SALMON (WASH.) SUBSTATIONS. 
There was a lighter fall run of chinook salmon in the Columbia 
River in the fall of 1920 than has occurred for several previous 
years. ‘To offset this there were not the intensive fishing operations 
witnessed throughout the period of the war, and the demand for 
chum and silver salmon was particularly light. As at all points 
in the Oregon field, the persistent high-water stages throughout 
the spawning period rendered the work of the spawn-taking crews 
difficult and hazardous, and at times the streams were quite beyond 
control. The run of chum salmon was of fair proportions, but it 
occurred at a time when it was possible to obtain only a limited 
number of eggs, and only a small proportion of the fish were ob- 
tained for propagation. During the run of silver salmon the floods 
were so severe as to make fishing impossible; therefore no eggs of 
this species were recorded. 
The collections of fish eggs at the Little White Salmon substation 
for the year consisted of 16,950,000 chinook salmon (of which 
2,000,000 were sent to the Big White Salmon substation and 1,100,000 
to the Clackamas station) and 5,162,000 chum-salmon eggs. This 
substation also handled 30,000 sockeye-salmon eggs transferred from 
the Washington field. At the Big White Salmon substation 5,005,000 
chinook-salmon eggs represent the total egg collections. 
ROGUE RIVER (OREG.) SUBSTATION, 
Operations at the Rogue River substation suffered less from the 
prevalent floods than at any other point in the field, and 4,438,000 
chinook salmon, 506,000 silver salmon, and 121,500 steelhead salmon 
egos were secured. There were on hand at the beginning of the year 
49.500 blackspotted trout, 886,000 steelhead salmon, and 197,000 rain- 
bow trout fry, all of which entered into the distribution from the 
station later in the year.
