1) The purpose of this project is to measure changes in juvenile salmon habitat occurrence and health following restoration activities at the Mirror Lake Complex and Horsetail Falls in the Lower Columbia River and estuary. Parameters measured include habitat conditions such as vegetation, water temperature, and dissolved oxygen; salmon diet and prey availability; weight, length, growth rate, lipid content, genetic stock, and chemical contaminant exposure. 2) Lyndal Johnson (NWFSC FTE) is the project lead, and other primary staff involved are Sean Sol and Paul Olson (NWFSC FTEs) and Kate Macneale (NWFSC term employee), but the project also involves other NWFSC FTEs, other term employees, contractors, and staff from other programs (Environmental Chemistry) and Divisions (FE, CB), as well as staff from collaborating agencies (e.g., the Lower Columbia River Estuary Partnership). 3) The project involves field surveys in which parameters measured include habitat conditions such as vegetation, water temperature, and dissolved oxygen; salmon diet and prey availability; weight, length, growth rate, lipid content, genetic stock, and chemical contaminant exposure. 4) Specific products to be produced include annual reports for the Lower Columbia Estuary Partnership, and manuscripts in peer-reviewed journals. 5) Specific audiences include (but are not limited to) the Bonneville Power Administration and other federal, state, and local agencies involved with salmon recovery and environmental management in the Columbia Basin (e.g., EPA, Washington Department of Ecology, Oregon Department of Environmental Quality, the City of Portland), the NMFS regional office, and other agency and academic scientists. 6) This is a stand-alone project, but it is also a component of a larger action effectiveness monitoring program overseen by the Estuary Partnership. 7) This is an ongoing project with a soft completion deadline; however, there are specific tasks to be completed on a yearly basis.

Prey composition in diet samples and water column tows at Lower Columbia River sites.

The Multnomah Channel Wetland Restoration Monitoring Project characterizes wetlands use by juvenile salmonids and other fishes in the Multnomah Channel Marsh Natural Area (MCMNA) and nearby habitats of the Columbia River estuary. The project is a collaborative program by federal, state, and municipal organizations evaluating the ecological effectiveness of floodplain restoration actions at the MCMNA on behalf of at-risk juvenile salmonids. The project uses a wide range of sampling methods to document fish, invertebrate prey, vegetation, and physical habitat conditions and to experimentally assess salmon performance. Sampling methods include: PIT arrays and remote detection systems to monitor salmon access, residency, and movements to and from the wetland; experimental net pens to compare salmon food and relative growth potential within different vegetation types; beach seines, traps, PIT detectors, electro-shockers, and other gear to monitor fish abundance and salmon stock composition; and benthic cores, insect fallout traps, emergent traps, and neuston nets to determine invertebrate prey composition, abundance, and transport from the wetland site. Fish samples are also collected along the main-stem estuary, Multnomah Channel, and other wetlands to investigate the effects of river flow and water elevation on fish access to the MCMNA. Invertebrate and fish stomach samples are analyzed at the main campus of Oregon State University (Corvallis, OR) and at the Oregon Department of Fish and Wildlife Corvallis Research Laboratory. Other activities, vessels, and sampling equipment are staged from the Pt. Adams Research Station in Hammond, OR. Species abundance, length, weight, residence time data for juvenile salmon in main stem Columbia R, Multnomah Channel. Mark and recapture data.

This data set contains sensitive biological resource data for anadromous fish species in Columbia River. Vector lines in this data set represent locations of anadromous fish spawning runs. Species-specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer.This data set comprises a portion of the Environmental Sensitivity Index (ESI) data for Columbia River. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. See also the FISH (Fish Polygons) data layer, part of the larger Columbia River ESI database, for additional fish information.
