"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 I, 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."

The lake has a maximum surface area of 975 acres and a volume of 7,150 acre-feet. Samples of fish killed after chemical treatment included coarsescale suckers 69.2 per cent, squawfish 24.5 per cent, redside shiners 3.0 per cent, black bullhead 2.0 per cent and bridgelip suckers 1.3 per cent. Chemical treatment of approximately 55 miles of tributary streams above Upper Cow Lake was completed in August and September, 1963. Twelve miles of tributary streams located in Idaho were treated by the Idaho Game Department personnel. Restocking of the lake with rainbow trout will begin in 1964. Very little of the tributary system is suitable for restocking of game fish." (Abstract from Author) Title: Habitat Improvement Project, No. 6 Author: Oregon. State Game Commission.

  Citation × Citation Citation Abstract Copy Title: Habitat Improvement Project, No. 25 Author: Oregon. State Game Commission. Fishery Division, Bisbee, Lawrence E. In earlier years, the lower Owyhee River provided excellent trout angling. In recent years, the fishery had declined to one maintained with the annual stocking of legal size hatchery trout on a put and take basis. Stream surveys completed in 1966 indicated the 16 1/2-mile section of the lower river lying between the Owyhee Reservoir dam and the old Owyhee diversion dam in Malheur County, Oregon, would lend itself to periodic rehabilitation and restocking annually with rainbow fingerling. Chemical treatment of this section of river was completed on March 18, 1967. A large population of bridgelip and coarsescale suckers, squawfish, chiselmouth, redside shiner, and carp were reduced. A kill estimated to be in excess of 63,000 fish resulted from the aerial application of 225 gallons of liquid pronox-fish by helicopter. Test fish confined in live boxes along with net sampling indicated an incomplete kill. Failure of the chemical to penetrate the deeper water and rapid detoxification were the primary causes for the incomplete kill. Detoxification at the old diversion dam was necessary to prevent destruction of warm-water game fish below. Rainbow fingerling totaling 97,642 were restocked in mid-April and 5,072 legal size rainbow were planted in late May 1967. Fingerling began entering the catch in August. Angler success was excellent.
