Upper Cow Lake located in Malheur County, Oregon, Township 28 South, Range 44 East, Section 29, was chemically treated with 2,325 gallons of liquid synergized rotenone (Pro-noxfish) on September 11, 1963 to remove an abundant population of rough fish. The lake has a maximum surface area of 975 acres and...
Big Lava Lake in Deschutes County, Oregon, was chemically treated September 19, 1963, to eliminate a population of roach and white fish. An estimated kill in excess of 400,000 fish resulted from the application of 4,620 gallons of liquid rotenone (Pro-Noxfish) at a toxicity of 2.0 ppm. Live -boxed brook...
Unity Reservoir in Baker County, Oregon, was chemically treated with liquid rotenone on October 17, 1962. Approximately 136 miles of streams and diversion ditches and seven small ponds, tributary to the reservoir, were treated with liquid rotenone prior to work on the reservoir. The reservoir at time of treatment contained...
Malheur Reservoir located in Malheur County, Oregon, was chemically treated with liquid rotenone on October 11, 1962 to eliminate an abundant population of black crappie and a smaller population of fine scale suckers and redside shiners.
Tests for toxicity indicated the reservoir had detoxified prior to December 1, 1962.

Malheur Reservoir in Malheur County, Oregon, was chemically treated on October 11, 1962, to eliminate an abundant population of black crappie and a smaller population of finescale suckers and redsided shiners. A total of 1,100 gallons of liquid synergized rotenone (Pro-Noxfish) was used to establish a toxicity of 1.5 p.p.m....
"Submitted herewith is report of a comprehensive survey and study of Oregon's wild life resource and the problems of wild life conservation and management in the state. The report presents numerous data on the principal species of wild life in Oregon and their habitat." (From Introduction)
Several streams in the mixed conifer cover type of the Ochoco and Blue Mountains of central Oregon were studied to determine what effects selective harvesting of the riparian timber stand had on the amounts and distribution of coarse woody debris (CWD) in the stream. Pristine streams were measured to develop...
Characteristics of low flows of nine streams in eastern Oregon were explored using long-term streamflow records. Year-to-year dependence of low flows is highly significant for streams in the Blue Mountain and the southeastern Oregon regions. Low streamflows increased over the period of record for seven of the selected streams. Flow...
Tracer-derived estimates of hydraulic resistance and transient hydraulic
storage were related to measures of pool volume and channel morphometric
variability in small streams of the Oregon coast, U.S.A. Fourteen
100 m study reaches in 3 streams were selected to compare channel
and hydraulic characteristics in streams representing a time series...
