This book was released on 1982 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research was conducted by NMFS in 1981 to define the effects of instream flows on the passage time, survival, and migrational behavior of 0-age chinook salmon in John Day Reservoir. Fourteen groups (74,683 fish) of marked 0-age chinook salmon were wire-tagged, branded, and released into the tailrace at McNary Dam, fourteen groups (13,746 fish) were branded and released into the reservoir at River Kilometer 375, and 34 groups (14,273) were branded and released into the reservoir at various other sites. More than 55,000 0-age chinook salmon were sampled at the John Day Dam airlift facility. This sample included 623 mark recoveries. Four hundred and eight (408) additional marks were recovered from purse seine samples taken at various sites throughout the reservoir. The average passage time of marked 0-age chinook salmon released in the McNary trailrace was 22 days in 1981. There was no statistically significant evidence to indicate that instream flows affected either the rate of movement or residence time of 0-age chinook salmon in John Day Reservoir in 1981. 7 references, 1 figure, 12 tables.

This book was released on 1983 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: The National Marine Fisheries Service in cooperation with the Bonneville Power Administration is conducting a 6-year study of the effects of instream flows on the passage time, survival, and migrational behavior of juvenile fall and summer (O-age) chinook salmon in John Day Reservoir. In 1982, the second year of the study, research activities concentrated on refining distribution and behavior data in John Day Reservoir and on releasing and recapturing marked fish needed to define flow/travel time relationships. Twenty-two groups (61,887 fish) of marked O-age chinook salmon were wire-tagged, branded, and released into the tailrace at McNary Dam, and forty-four groups (13,128 fish) were branded and released into the reservoir at various other sites. Sampling at the John Day Dam airlift facility captured 54,647 subyearling chinook salmon including 482 marked recoveries. Additional marks (279) were recovered from purse seine samples taken at various sites throughout the reservoir. The average passage time to John Day Dam for marked O-age chinook salmon released in the McNary tailrace was 23 days. Weekend flow reductions at McNary Dam did not affect passage time of subyearling chinook salmon in John Day Reservoir. There was no statistical evidence to indicate that instream flows affected either the rate of movement or residence time of O-age chinook salmon in John Day Reservoir.

This book was released on 2005 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides information on PIT-tagging of wild Chinook salmon parr in Idaho in 2003 and the subsequent monitoring of these fish and similarly tagged fish from Oregon. We report estimated parr-to-smolt survival and arrival timing of these fish at Lower Granite Dam, as well as interrogation data collected at several other sites throughout the Snake and Columbia River system. This research continues studies that began under Bonneville Power Administration (BPA) funding in 1991. Results from previous study years were reported by Achord et al. (1994; 1995a, b; 1996a; 1997; 1998; 2000; 2001a, b; 2002, 2003, 2004). Goals of this ongoing study are: (1) Characterize the migration timing and estimate parr-to-smolt survival of different stocks of wild Snake River spring/summer Chinook salmon smolts at Lower Granite Dam. (2) Determine whether consistent migration patterns are apparent. (3) Determine what environmental factors influence migration patterns. (4) Characterize the migration behavior and estimate survival of different wild juvenile fish stocks as they emigrate from their natal rearing areas. This study provides critical information for recovery planning, and ultimately recovery for these ESA-listed wild fish stocks. In 2003-2004, we also continued to measure water temperature, dissolved oxygen, specific conductance, turbidity, water depth, and pH at five monitoring stations in the Salmon River Basin, Idaho for the Baseline Environmental Monitoring Program. These data, along with parr/smolt migration, survival, and timing data, will help to discern patterns or characteristic relationships between fish movement/survival and environmental factors.

This book was released on 1984 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effects of instream river flow on the passage time, survival, and migrational behavior of juvenile fall and summer (O-age) chinook salmon in John Day Reservoir is being studied. In 1983, the final year of juvenile sampling in the reservoir, research activities continued to refine flow/travel time relationships and distributional behavior of O-age chinook salmon. Fifteen groups (72,559 fish) of marked O-age chinook salmon were wire-tagged, branded, and released into the tailrace at McNary Dam, and thirty-two groups (22,206 fish) were branded and released into the reservoir at various other sites. Sampling at John Day Dam, utilizing the airlift pump system in the B and C slots of Turbine Intake Unit 3, captured 82,698 subyearling chinook salmon including 640 mark recoveries. Additional marks (458) were recovered from purse seine samples taken at various sites throughout the reservoir. Weekly mean fork lengths of O-age chinook salmon captured at McNary and John fsm Dams and in the reservoir by purse seine ranged from 103 mm in mid-June to 166 mm in mid-December. Fish captured at the John Day Dam monitoring facility and by purse seine throughout the reservoir were in excellent condition. Preliminary analysis of stomach samples taken in 1982 and 1983 from purse seine catches indicates active feeding is taking place. The average passage time of the fastest moving marked O-age chinook salmon from McNary Dam to John Day Dam was 11 days (based on 25th percentile of mark recaptures). The average reservoir residence time was 22 days. Regression analysis was used to develop a description of the relationship of river flow to the rate of downstream movement of O-age chinook salmon in John Day Reservoir in 1983. The slope of this line and the correlation coefficient (R) were not significantly different from zero.

Available in PDF, EPUB and Kindle. Book excerpt: In 2007, we used radio and acoustic telemetry to evaluate the migratory behavior, survival, mortality, and delay of subyearling fall Chinook salmon in the Clearwater River and Lower Granite Reservoir. Monthly releases of radio-tagged fish ((almost equal to)95/month) were made from May through October and releases of 122-149/month acoustic-tagged fish per month were made from August through October. We compared the size at release of our tagged fish to that which could have been obtained at the same time from in-river, beach seine collections made by the Nez Perce Tribe. Had we relied on in-river collections to obtain our fish, we would have obtained very few in June from the free-flowing river but by late July and August over 90% of collected fish in the transition zone were large enough for tagging. Detection probabilities of radio-tagged subyearlings were generally high ranging from 0.60 (SE=0.22) to 1.0 (SE=0) in the different study reaches and months. Lower detection probabilities were observed in the confluence and upper reservoir reaches where fewer fish were detected. Detection probabilities of acoustic-tagged subyearlings were also high and ranged from 0.86 (SE=0.09) to 1.0 (SE=0) in the confluence and upper reservoir reaches during August through October. Estimates of the joint probability of migration and survival generally declined in a downstream direction for fish released from June through August. Estimates were lowest in the transition zone (the lower 7 km of the Clearwater River) for the June release and lowest in the confluence area for July and August releases. The joint probability of migration and survival in these reaches was higher for the September and October releases, and were similar to those of fish released in May. Both fish weight and length at tagging were significantly correlated with the joint probability of migrating and surviving for both radio-tagged and acoustic-tagged fish. For both tag types, fish that were heavier at tagging had a higher probability of successfully passing through the confluence (P=0.0050 for radio-tagged fish; P=0.0038 for acoustic-tagged fish). Radio-tagged fish with greater weight at tagging also had a higher probability of migrating and surviving through both the lower free-flowing reach (P=0.0497) and the transition zone (P=0.0007). Downstream movement rates of radio-tagged subyearlings were highest in free-flowing reaches in every month and decreased considerably with impoundment. Movement rates were slowest in the transition zone for the June and August release groups, and in the confluence reach for the July release group. For acoustic-tagged subyearlings, the slowest movement rates through the confluence and upper reservoir reaches were observed for the September release group. Radio-tagged fish released in August showed the greatest delay in the transition zone, while acoustic-tagged fish released in September showed the greatest delay in the transition zone and confluence reaches. Across the monthly release groups from July through September, the probability of delaying in the transition zone and surviving there declined throughout the study. All monthly release groups of radio-tagged subyearlings showed evidence of mortality within the transition zone, with final estimates (across the full 45-d detection period) ranging from 0.12 (SE not available) for the May release group to 0.58 (SE = 0.06) for the June release group. The May and September release groups tended to have lower mortality in the transition zone than the June, July, and August release groups. Live fish were primarily detected away from shore in the channel, whereas all dead fish were located along shorelines with most being located in the vicinity of the Memorial Bridge and immediately upstream. During the May detection period, before the implementation of summer flow augmentation, temperatures in the Clearwater River and Snake River arms of Lower Granite Reservoir and the downstream boundary of the confluence ranged from 8 to 17 C. During the June-August detection periods, however, temperatures in the Clearwater River arm ranged from 10-16 C down to 7 m and the Snake River arm was above 20 C down to a depth of 9 m. Incomplete mixing between the two water sources resulted in significant vertical temperature variation at the downstream boundary of the confluence during a large portion of the June-August detection periods. This variation diminished during the September and October detection periods when temperatures once again fell to 17 C and lower and eventually became uniformly distributed throughout the water column in the confluence.
