Abstract	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 trout were used to determine toxicity duration. Twenty-five trout live-boxed in five sets on October 14 were all alive when the live boxes were removed October 25. Brook trout, totaling 254,573, were stocked in Big Lava October 29 and 30, and November 6, 1964.
