"Clear Creek, tributary of North Fork John Day River, is a mountain stream located in the Blue Mountains of eastern Oregon. It joins Granite Creek about 1.5 miles below the old abandoned mining town of Granite. Gravel removed from Clear Creek by gold dredging activity was replaced in a 3.37-mile section of the stream in 1961. The purpose of this work was to provide new spawning areas and resting pools to accommodate adult spring chinook salmon."

"The Tenmile Lakes Project for partial control of warm-water fish was initiated in August of 1964, One qualified fishery biologist and one conservation aide were assigned to do the work. 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.

Additional incidental assistance and equipment were supplied by the Fish Commission personnel from the Charleston, Oregon, laboratory."

"Upper Cow Lake located in Malheur County, Oregon, Township 28 South, Range 44 East, Section 29, was chemically treated with 2,325 gallons of liquid synergized rotenone (Pro-noxfish) on September 11, 1963 to remove an abundant population of rough fish. 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.

Tex Creek, tributary to Murderers Creek which flows into the South Fork John Day River, was chosen as the study stream because of its history of steelhead use and loss of young due to intermittent flow in slimmer months. The Tex Creek study was designed to test subterranean structures that might raise and direct subsurface water into the stream channel to prevent intermittent summer flow...The all-plastic structures which extended across the valley floor were effective in raising subsurface water, while the shorter barriers located across the stream channel only were not...A trap was operated at the mouth of the stream to record upstream and downstream migrant fish.

"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."

  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.
