Observations of the Behavior and Distribution of Fish in Relation to the Columbia River Navigation Channel and Channel Maintenance Activities. Full Record;. The movements and dam passage of juvenile Chinook salmon implanted with acoustic transmitters and passive integrated transponder tags were studied at Cougar Reservoir and Dam, near Springfield, Oregon. The purpose of the study was to provide information to aid with decisions about potential alternatives for improving downstream passage conditions for juvenile salmonids in this flood-control.

Reagan, Patrick J. Connolly, Noah S. Author: Rachel E. Reagan, Patrick J. Connolly, Noah S. Adams, Matthew G. Mesa, Dennis W. Rondorf. Swans, ducks and geese are found on every continent and throughout Oregon. Swans, ducks and geese belong to the Anatidae family and occur on all continents. Special oils let their feathers shed water, so they are adapted for swimming and floating, and some are even talented divers. For tips on discouraging geese from overwhelming your yard.

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.

A total of 43 fish ( percent) passed Detroit Dam from the. Behavior of juvenile salmonids migrating through the Willamette River near Portland, Oregon.

Factors that limit survival and production of largemouth bass in Upper Klamath and Agency lakes, Oregon.

Willamette River are spring-run fish that outmigrate as subyearlings. The outmigration period for Chinook salmon, both hatchery and unmarked, was surprisingly long. The presence of juvenile fish often increased in late autumn and persisted into the next summer, and juvenile salmonids were present in every month we sampled from May to July We investigated the effects of Portland Harbor development in the lower Willamette River on the migration and behavior of juvenile salmonids (Oncorhynchus spp.), the habitat occupied by juvenile salmonids, and predation on juvenile salmonids by northern squawfish Ptychocheilus oregonensis.

In-reservoir behavior, dam passage, and downstream migration of juvenile Chinook salmon and juvenile steelhead from Detroit Reservoir and Dam to Portland, Oregon, February February   Early ocean experience is a critical time period that affects juvenile salmonid survival.

Understanding juvenile salmonid behavior in nearshore marine environments and how oceanic conditions (such as dynamic river plume habitats) affect salmonid migration will contribute to salmonid survival studies and conservation and management efforts.

In the second year of 2 years of study, the movements of juvenile spring Chinook salmon (Oncorhynchus tshawytscha) and juvenile summer steelhead (Oncorhynchus mykiss) through Detroit Reservoir, passing Detroit Dam, and migrating downstream to Portland, Oregon, were studied during a 1-year-long period beginning in February   In the mids, concerns about the effects of waterway development on juvenile salmonids led to a cooperative study between the Port of Portland and the Oregon Department of Fish and Wildlife (ODFW) ().The study focused primarily on the Portland Harbor area (rkm –) and concluded that (1) with the exception of habitat losses caused by seawall construction, development Cited by: Work Completed for Compliance with the Willamette Project Biological Opinion, USACE funding: JUVENILE SALMONID OUTMIGRATION MONITORING AT WILLAMETTE VALLEY PROJECT RESERVOIRS Prepared for U.

Johnson, Thomas A. File Size: KB. In the Willamette River basin, USA, fall and spring wild juvenile migrants differ in body morphology (Billman et al., ), and we found that variation in egg size appears to be correlated with similar morphological differences.

As we predicted, body morphology of fish from small eggs was more similar to the deep‐bodied fall migrant, while Cited by: 3.

These often do not represent fish or environmental conditions in smaller rivers and may not be applicable to the Klamath River. The process of downstream migration of juvenile coho salmon is.issue in the lower Willamette River for spring-migrating juvenile salmonids.

This is a result of bass feeding behavior, juvenile salmonid migration timing, and habitat parameters. There are some suggestions in the scientific literature, however, that smallmouth bass might consume more sub-yearling chinook salmon during summer.
