COLUMBIA RIVER AND TRIBUTARIES. 



The first fish-cultuial work upon the Columbia River and in Oregon 

 was at Clackamas, on the Clackanas River, a tributary of the Willam- 

 ette River, which empties into the Columbia River about 180 miles 

 from its mouth. 



This hatchery was built in 1876 by the Oregon & Washington Fish 

 Propagating Co., which operated it until 1880. In 1887 the vState 

 provided for and there was app)ointed a State fish commission. 

 Almost the first work of the commission was to spend $12,000 appro- 

 priated by the legislature to put in repair and oj)erate this hatcnery. 

 On July 1, 1888, it was informally turned over to the United States 

 Commission of Fish and Fisheries, which paid over the purchase 

 price, took formal possession in the following winter, and has oper- 

 ated it ever since, with the exception of several years when the build- 

 ing of dams stopped the progress of salmon to the hatchery. During 

 this period a temporary station for the collection of eggs was estab- 

 lished on Sandy River, about 15 miles away, and on Salmon River, 

 a tributary of Sandy River, both tributaries of the Columbia River. 

 Some eggs were also brought in from the California hatcheries and 

 hatched at the Clackamas station. In 1901 the hatchery was moved 

 about 4 miles down the river and has since been operated as both 

 a roariiif' and a collecting station. In 1901 the State established 

 another hatchery on the Clackamas River about 30 miles below the 

 main station and betwec^n the north and south forks. In 1904 all 

 were turned over to the United States. In 1915 the hatchery was 

 moved again. In 1907 an experimental station for the collection of 

 eggs of trie early variety of chinook salmon was established by the 

 State of Oregon on the Clackamas River below the Portland Railway, 

 Light & Power Co.'s dam at Cazadcro, but this was later opei-ated by 

 the United States Bureau of Fisheries. The building of a dam having 

 cut off this station, another was established in 1913 at a point 30 miles 

 distant from Portland.
