36 U. S. BUREAU OF FISHERIES. 



APPLKGATE C'KEKK (OKEO.) .SUBSTATION. 



Fish-cultural operations at this point involved the silver salmon 

 and the steelhead. The spawning season of the former extended 

 from November 28 to January 16, while eggs were taken from the 

 other species between January 16 and May 16, the collections 

 amounting to 2,458,000 and 3,266,000, respectively. The changes 

 made in the fishing racks during- the past season proved highly 

 satisfactory, and this imi^rovement, together with the favorable 

 climatic conditions i^revailing throughout the season, made it pos- 

 sible to secure a very fair collection of eggs. 



The usual transfers of eyed eggs were nxacle, including steelhead 

 eggs, to the Rogue River station, the Oregon State hatchery at Butte 

 Falls, Oreg., and to eastern applicants. The retained eggs produced 

 a remarkably high j)ercentage of fry, all of which were successfully 

 reared to fingerlings No. 1^ and No. 2 before releasing in local 

 streams. About 600,000 fingerling steelheads renuiined on hand at 

 the end of the year. 



SANDY RIVER (OREG.) SUBSTATION. 



The previous year's fish-cultural operations at the Sandy River 

 site having proved eminently successful, it was deemed advisable to 

 establish a permanent substation at that point. With this end in 

 view a hatchery building, 29 by 58 feet, of frame construction on 

 a cement foundation, a water supply line, and a four-room cottage 

 were constructed and made ready for the work in advance of the 

 spawning season. 



The numbers of chinook and silver salmon reaching the racks 

 were small as compared with last year's run, the decline being at- 

 tributed to the diversion of a considerable portion of the river water 

 supply to the operation of a hydroelectric plant in the vicinity. Not- 

 withstanding this handicap, chinook-salmon eggs to the number of 

 461,900 were secured, the spawning season extending from August 

 22 to December 7. Water conditions in the river were improved 

 during the spring months, and between March 31 and the end of 

 the first w^eek in June 832,600 steelhead and 330,600 silver-salmon 

 eggs were collected. 



The Sandy River substation is located near the base of Mount 

 Hood, and the winters are sometimes so severe that slush ice occurs 

 in the river. Taking this fact into consideration, provision has 

 l)een made for the construction of a flume to conduct water from 

 the river and also for an auxiliary flume between the hatchery and 

 Spring Creek. By this means the possible failure of the Avater sup- 

 ply during periods of intense cold is guarded against. 



Under normal conditions there is a good run of the highly prized 

 chinook salmon, and also of the steelhead in Sandy River, and the 

 site gives promise of fruitful results at a low cost for maintenance. 



WASHOUGAL RIVER (WASH.) SUBSTATION. 



This eying station was in operation during the spawning season 

 of the steelhead, from April 13 to May 23, during which period 

 834,000 eggs were taken. A heavy run of fish passed up the river;
