from Little White Salmon (Wash.) station, 100,000 blackspotted 

 trout from INIontana 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. 



ITPPEB CLACKAMAS (OBEG.) 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 U])per 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 IG, when 

 higli water permitted the escape of all remaining hsh, 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 Clackanuis River is difficult to protect against the poacher, and 

 illegal fishing is prevalent. 



IJTTI.IC WIIITIO SAT.MON AND BIf) WHITE SALMON (WASH.) SUBSTATIONS. 



Tliere 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 

 chuui and silver sahnon was particularly light. As at all points 

 in llie Oi-egon field, the persistent high-water stages throughout 

 the si)awning 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 16,9.50,000 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. 



KOGUK RIVKU (ORKfl.) .STTBSTATION. 



Operations at the Rogue River substation suffered less from the 

 prevalent floods than at any other ]:>oint in the field, and 4,488,000 

 chinook salmon, 506,000 silver salmon, and 121,500 steelhead salmon 

 eggs 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.
