"The upper drainage of the John Day River system produces summer steelhead and spring chinook salmon. The fish are generally confined to the main stem and its tributaries above Prairie City. The spawning and rearing areas are comparatively free of undesirable fish species, but salmonid smolts migrating downstream must travel through populations of large predatory squawfish. The purpose of the study was to determine if salmonid smolt survival could be increased through removal of the large squawfish by treatment with rotenone. A 40-mile section of the John Day River between Dayville and John Day was selected for study. A pretreatment fish population inventory was conducted to determine the species and numbers of fish present within the test area. Significantly large populations of undesirable fish and correspondingly low numbers of salmonids were observed in the test area...Posttreatment inventory of fish populations within the study area has shown that average size and number of squawfish was effectively reduced and that salmonid numbers can be increased by temporary control of rough fish populations."

The reduction in assigned personnel was due to lack of funds. Although this was to be a joint project with the Oregon Game Commission and the Fish Commission of Oregon, the Fish Commission was unable to particpate directly because funds were not authorized. Plankton data were supplied by Alan M.

  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.

"The construction of Illinois Falls fish ladder on the Illinois River in Oregon was completed in November 1961. The ladder was opened and operated during the winter of 1961-62. Final cleanup and rock removal was completed in the fall of 1962. The ladder was installed on a natural barrier where fish passage was delayed by low and moderately high river levels. The facility installed was a concrete vertical baffle-type fishway patterned after the Hells Gate fishway in use on the Fraser River in Canada. Since the ladder has been installed, salmon and steelhead have arrived at upper river areas much earlier than previously recorded. Concentrations of fish have not been observed below the falls."

Fintrol-5 was experimentally tested in six isolated gold dredge ponds in Sumpter Valley. The tests revealed all coarse fish in treated ponds were killed in a period varying between 7 hours and 144 hours; toxic water subbing from treated ponds would kill fish in downstream ponds if water table dillution was not too great; and, the period of toxicity varied from 2 days to 12 days in treated ponds, dependent upon rate of water exchange. One pond without water exchange was treated at a concentration of .075 ppb. All but 30 fish were killed. Title: Habitat Improvement Project, No. 26 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.
