REPORT OF COMMISSIONER OF FISH AND FISHERIES. LXIX 



With the view to testing the advantages to be derived from planting 

 fry near the ocean, arrangements were made for hatching 750,000 of 

 the eggs collected at the State experimental station at Olema, Gal. 

 They were shipped on December 31, and the resulting fry were planted 

 during February and March in Dutch Bill, Boccacio, Olema, and Bear 

 Valley creeks. Their movements were carefully noticed by Messrs. 

 A. B. Alexander and N. B. Scofield. 



Clackamas Station, Oregon (W. F. Hubbard, Superintendent). 



The superintendent was occupied during a portion of the summer in 

 examining a number of tributaries of the Columbia Eiver, with the view 

 to establishing auxiliary stations, to be operated in connection with the 

 station on the Clackamas. As a result of his investigations, arrange- 

 ments were made for the collection of eggs on the Salmon River, a 

 tributary of the Sandy, and on the Little White Salmon, emj)tying into 

 the Columbia above the Cascades, in the State of Washington. The 

 collections on the Snake and Sandy rivers the previous year were so 

 small that it was decided not to operate at those points again. 



Early in July the station force commenced the construction of a rack 

 330 feet long across the Clackamas River. Great difficulty was expe- 

 rienced in this undertaking on account of the extensive rafting of logs 

 and wood from points above, but arrangements were finally made with 

 the lumbermen to provide a boom, and a gate was built in the rack to 

 permit of the passage of the material. The rack was completed on July 

 18, and the force was utilized during the remainder of the summer in 

 making repairs to the boats and fishing apparatus, building a trap for 

 the capture of spawning fish, and laying a new floor in the hatchery. 

 The collection of eggs from the fish below the rack was commenced 

 on September 11, and operations were continued until October 31, the 

 total take amounting to 1,062,500. On that date a part of the rack was 

 carried away by a rise in the river, and, as it was late in the season and 

 there appeared to be very few fish below the rack, no attempt was made 

 to repair it. 



The results of the season's work were very discouraging, as the traps 

 and seines had been worked night and day, and gill nets had also been 

 fished on the riffles below, where a few salmon were observed spawning. 



Early in November the volume of the spring brook was so increased 

 by heavy rains that the pumps were discontinued and the supply for 

 the hatchery taken from that source. Considerable damage was done to 

 the station during the month by high water. The bridge across Clear 

 Creek was carried away on the night of November 8, and on the 13th 

 the river rose 13 feet above its normal level, carrying away the plank 

 breakwater built in 1877, covering and greatly damaging the land about 

 the station, and flooding the hatchery so that a boat could be brought 

 into the door. 



Shii)ments of eggs aggregating 2,340,000 were received from the 

 Salmon River station between September 11 and October 0. The fry
