Part I. To aid in the management of the Tillamook Bay commercial salmon fishery, a tagging program was conducted on the salmon and steelhead trout runs in 1953. General migration behavior, the minimum length of time the fish remained in the fishery, population sizes, and fishing mortalities were determined from...

Station at Corvallis (COR) and a seismic station at Klamath Falls (KFO),
Oregon.
The Corvallis station includes three short-period Benioff seismographs
(To = 1 sec, Tg = 0.75 sec), three long-period Sprengnether
seismographs (To = 30 sec, Tg = 100 sec), and...

Miller Lake was chemically treated with toxaphene on September 16, 1958 to destroy a population of parasitic lamprey (E.tridentatus) and Tui Chub (Siphatelep bicolor). Toxaphene was applied at the rate of 0.04 ppm. No lamprey or fish have been collected in the lake since the chemical treatment. Work since 1959...
