Survival Estimates for the Passage of Spring-Migrating Juvenile Salmonids through Snake and Columbia River Dams and Reservoirs, James R. Faulkner, Steven G. Smith, William D. Muir, Douglas M. Marsh, and Richard W. Zabel. Report of research by. Fish Ecology Division. Northwest Fisheries Science Center. National Marine Fisheries Service. The in situ depths of juvenile salmonids Oncorhynchus spp. were studied to determine whether hydrostatic compensation was sufficient to protect them from gas bubble disease (GBD) during exposure to total dissolved gas (TDG) supersaturation from a regional program of spill at dams meant to improve salmonid passage survival. Yearling Chinook salmon O. tshawytscha and juvenile .
In the early s, the US Army Corps of Engineers implemented a fish transportation program to reduce exposure of migrating juvenile salmonids Oncorhynchus spp. to sources of mortality associated with hydrosystem development in the Columbia Basin, USA (Ward et al., ).Juvenile fish are collected and loaded into fish-transport barges (>90% of fish Cited by: 9. Evidence from tagging studies indicate higher straying rates in adults that were transported as juveniles compared to those that migrated in river, potentially hindering salmon and steelhead recovery efforts.

Boat wakes in the Rogue River, Oregon, did not appear to change the thermal properties of thermal refuges of juvenile Chinook salmon Oncorhynchus. Defendants emphasize that the Juvenile Salmonid Study found that tour boat operations did not have significant effects on juvenile salmonids. RogueJets AR, ABK.
While the study stated that tour boat use could increase the mortality of juvenile salmonid in areas of gravel nests, it found that the proportion of adult salmon had increased despite an increase in the size and number of tour boats.
Multiple dam passage during seaward migration is thought to reduce the subsequent survival of Snake River Chinook salmon. This hypothesis developed because juvenile Chinook salmon from the Snake River, the Columbia River’s largest tributary, migrate > km through eight hydropower dams and have lower adult return rates than downstream Cited by: juvenile salmonids as a means to mitigate for downstream losses that result from passage through the lower Snake and Columbia River federal hydropower system.
The U.S. Army Corps of Engineers funds annual transportation studies to inform management decisions on which operational strategies are most likely to maximize numbers of returning adults.

We examine how the estuary supports viability of anadromous salmonid populations, review what is known about juvenile salmon in the Columbia River estuary, examine how changes in selected factors associated with the estuary.

the understanding of the migratory behavior and survival of juvenile salmonids emigrating through the lower km of the Columbia River and estuary. This understanding is critical to determining the effects of the Federal Columbia River Power System (FCRPS) on the ‘post-hydrosystem’ performance of these populations.

Faulkner, Steven G. Smith, William D. Muir, Douglas M. Marsh, and John G. Williams Report of research by Fish Ecology Division Northwest Fisheries Science Center National Marine Fisheries Service. Spill has long been considered one of the safest routes of passage for juvenile salmonids at Snake and Columbia River hydroelectric projects.

Also, thisprogramwastoprovide datato.An evaluation was conducted to estimate dam passage survival of juvenile Chinook salmon (Oncorhynchus tshawytscha) at Detroit Dam during a period of spill. To estimate dam passage survival, we used a paired-release recapture study design and released groups of tagged fish upstream ( fish) and downstream ( fish) of Detroit Dam.
