"South Twin Lake in Deschutes County, Oregon was chemically treated September 14, 1965, to eliminate a population of Tui Chub (Siphateles bicolor). A total of 605 gallons of liquid synergized rotenone and 9,750 pounds of powdered rotenone was applied to the lake. It was estimated that 130,000 mature chub were killed. Only a small number of rainbow trout were found in the lake. Live-boxed rainbow were used to determine toxicity duration. Eight trout live-boxed in three sets fourteen days after treatment experienced no mortality after six days exposure to the lake water. Rainbow trout totaling 5,014 were stocked November 24, 1965."

  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.

  Citation × Citation Citation Abstract Copy Title: Habitat Improvement Project, No. 24 Author: Oregon. State Game Commission. Fishery Division, Bauer, Jerry A. Fish passing Winchester Dam view-window counting station on the North Umpqua River were enumerated. Figure 1 is a map of the Umpqua basin and denotes the counting station. The counts for summer steelhead, fall chinook, and sea-run cutthroat increased while those for winter steelhead, spring chinook, and coho decreased. By far the greater number of fish again passed through the station from Noon to 8 p.m. The contribution of the hatchery and rearing pond programs to the anadromous fishery was demonstrated by the numbers of marked fish returning (1008 and 6700 percent of each run). Substantially higher returns from March releases over fish stocked in either April or May is indicated. (From the abstract) Title: Habitat Improvement Project, No. 24 Author: Oregon.
