Abstract
  • 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. A progress report outlining the actual chemical treatment was distributed as Habitat Improvement Project, Fishery Division, Oregon State Game Commission, Number 1. The reservoir was restocked in 1963 with 270,845 rainbow trout fingerling weighing 1,363 pounds. A fishery developed by late July and continued until the end of the trout season on October 31, 1963. It was estimated that a total of 2,300 anglers fished the reservoir in 1963. Fish population studies were conducted and some problem areas were re-treated with rotenone.
