  Citation × Citation Citation Abstract Copy Title: Growth, residence, and movement of juvenile Chinook salmon within restored and reference estuarine marsh channels in Salmon River, Oregon. Author: Hering, David K. Tidal wetland channels provide rearing habitat for juvenile Chinook salmon as they emigrate from freshwater habitat and prepare to enter the ocean. Widespread diking and drainage of estuarine marshes for agricultural and urban development may have contributed to a decline in salmon abundance in the Pacific Northwest, prompting efforts to restore estuarine salmon habitat in the region. I investigated the growth and residence patterns of age-0 Chinook salmon in two blind tidal channels in the Salmon River estuary, Oregon. One channel drained a natural high salt marsh in “reference” condition, and the other channel was in an adjacent salt marsh, restored to tidal inundation in 1996 after being diked and controlled by a tide gate for thirty five years. Recapture of individually marked fish indicated salmon growth rates were similar in the two channels, though growth rates varied more seasonally in the restored site. Average minimum residence times of individual fish were approximately ten days in each channel, and individual salmon were observed up to 79 and 117 days after initial marking in the reference and restored channels, respectively. To characterize movement of age-0 salmon within tidal channels, I tested the feasibility of stationary Passive Integrated Transponder (PIT) detection within a small (approximately 8m wide) tidal channel within the natural marsh system. I found that a stationary PIT detector was an effective tool for monitoring tagged fish movement in a brackish water channel network. Salmon movements in the channel were asymmetrical about high slack tide, with peak movement frequency occurring late during both flood and ebb tide periods. Most movements were in the direction of tidal currents, but 20% of individuals entered the channel against the ebbing tide. Individuals occupied the intertidal channel for a median 4.9 hours and as long as 8.9 hours per tidal cycle, and few were detected moving when water depth was <0.4m. Some individuals used the channel on multiple successive tidal cycles, and others entered intermittently over periods up to 109 days. This research used individual-based fish marking methods to quantify juvenile Chinook salmon behavior and performance within tidal marsh channels, assessing functional equivalence of natural and restored sites and demonstrating the value of such habitats for conservation and restoration of salmon populations.

This stream is a 4th order contributor to Rock Creek, which joins the Siletz River near Logsden, Oregon. The stream has been prioritized for restoration by the Midcoast Watershed Council because it appears to provide the best remaining spawning and rearing potential within the Rock Cr. basin. The report contains information on the physical setting, current status of Coho, resources used in developing the plan, general questions that guided the assessment, pre-survey mapping/location of habitat subdivisions, secondary branch habitats, critical contributing areas, lowland area, summer and winter habitat assessment, lake habitat, location of other resources, juvenile Coho, evaluation of habitat quality and Coho production, Field Assessment, location of potential migration barriers, potential sites for restoration work, morphology, rank of restoration efforts, riparian corridor, and core area.

  Citation × Citation Citation Abstract Copy Title: Limiting factors assessment and restoration plan Rock Creek : tributary to Devil's Lake, Lincoln County, Oregon Author: Bio-Surveys, LLC, Sialis Company This document provides watershed restoration actions proposed to enhance the Coho Salmon population within the Rock Creek / Devils Lake basin in Lincoln County, Oregon. The stream is the principle tributary of Devil’s Lake, a lake of natural origin that opens into the Pacific Ocean at the northern edge of Lincoln City, OR. The goal of the restoration effort has been to identify the dominant processes and habitat characteristics that currently limit the production of Coho salmon smolts in the basin, and to develop a prioritized list of actions (“prescriptions”) for removing the limitations in ways that normalize landscape and stream channel function. Restoration and assessment protocols used in developing the plan are described in “Midcoast Limiting Factors Analysis, A Method for Assessing 6th field subbasins for Restoration”, available at www.midcoastwatershedcouncil.org/GIS or by contacting the Midcoast Watersheds Council.

  Citation × Citation Citation Abstract Copy Title: Multiscale habitat electivity and movement patterns by adult spring chinook salmon in seven river basins of northeast Oregon Author: Price, David M. I examined habitat electivity and movement patterns of adult spring chinook salmon at microhabitat and channel unit spatial scales, and seasonal to annual temporal scales in seven streams in the Grande Ronde, John Day, and Imnaha basins. The objective was to compare habitat use and availability among streams, channel units, and microhabitats, and to assess chinook salmon fidelity to those habitats using radio-telemetry. The analyses showed that habitat quality and availability in the seven study streams varied. Each stream posed different physical constraints on adult chinook salmon habitat; this was reflected by the differential use of habitat by salmon among streams. Salmon elected pools almost exclusively in the John Day Basin, whereas pools and riffles were elected in near equal proportion in the Grande Ronde and Inmaha basins. Within streams, use was similar between years. Almost all salmon were observed in association with cover, but the type of cover largely reflected availablity. Chinook salmon elected the deepest depths within channel units (microhabitat scale), but not necessarily the deepest channel units among streams (channel unit scale). Chinook salmon did not elect cooler stream temperatures within channel units in any study stream, except the Middle Fork John Day River. Radio-tagged chinook showed a high fidelity to habitats, except when stream temperatures approached lethal limits. Due to stream specific differences in habitat availability and use, multiscale habitat assessments for individual streams are recommended to increase the success of watershed restoration activities.
