The Coho Tasks Database contains the Implementation Tasks from tables 9.1, 9.2, and 9.3 of the Recovery Strategy for California Coho Salmon (2004). The data was normalized and cross-referenced to Calwater 2.2.1 watershed units. Some updates were performed in 2005 and are noted in the data. The database contains a set of related tables primarily related to the TASK table. The TASK table includes a description of the activity to perform. The PRIORITY table contains the description of the coded TASK.PRIORITY column. Similarly, the LEVEL table contains the description for the coded TASK.LEVEL column. The TASK_FOOTNOTE table is a many-to-many bridge between the TASK and FOOTNOTE tables. This captures the footnotes for tasks from the original document. Finally, the TASK_CALW contains the mapping of TASK records to Calwater 2.2.1 records. A task may be mapped to zero or more TASK_CALW records. This data and metadata were submitted by California Department of Fish and Wildlife (CDFW) Staff though the Data Management Plan (DMP) framework with the id: DMP000714.

Critical habitat includes the water, substrate, and adjacent riparian zone of estuarine and riverine reaches (including off-channel habitats). The riparian area is defined as the area adjacent to a stream that provides the following functions: shade, sediment, nutrient or chemical regulation, streambank stability, and input of large woody debris or organic matter.See the final rule (64 FR 24049) for descriptions of areas excluded from this critical habitat designation. Excluded Indian lands were not clipped out of the data.

The Recovery Action Mapping Tool is a web map that allows users to visually interact with and query actions that were developed to recover species listed under the Endangered Species Act. This tool serves as a data portal to gather information about the work being done across a vast geographic area, and facilitate a better and broader understanding of species management. Implementers adjust recovery actions based on monitoring and research results, which highlight how well species are responding to actions and evolving local conditions.

Critical habitat includes the stream channels within the designated stream reaches, and includes a lateral extent as defined by the ordinary high-water line (33 CFR 319.11). In areas where ordinary high-water line has not been defined, the lateral extent is defined by the bankfull elevation. Bankfull elevation is the level at which water begins to leave the channel and move into the floodplain and is reached at a discharge which generally has a recurrence interval of 1 to 2 years on the annual flood series. Critical habitat in lake areas is defined by the perimeter of the water body as displayed on standard 1:24,000 scale topographic maps or the elevation of ordinary high water, whichever is greater.See the final rule (73 FR 7816) for descriptions of areas excluded from this critical habitat designation. Excluded Indian lands were not clipped out of the data.

Count of total number of Coho Salmon (Oncorhynchus kisutch) observed in a two hour period

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. Juvenile chinook salmon diet composition and prey availability in habitat.

Physical and chemical changes affect the biota within urban streams at varying scales ranging from individual organisms to populations and communities creating complex interactions that present challenges for characterizing and monitoring the impact on species utilizing these freshwater habitats. Salmonids, specifically cutthroat trout (Oncorhynchus clarkii) and coho salmon (Oncorhynchus kisutch), extensively utilize small stream habitats influenced by a changing urban landscape. This study used a comprehensive fish health assessment concurrent with the U.S. Geological Survey’s Pacific Northwest Stream Quality Assessment in 2015 to quantifiy impacts from disease in juvenile coho and cutthroat salmon, impacts to coho salmon growth within the context of environmental and ecological influences, and identify physiological responses in coho salmon from pollution. The data included in this release informed a study of the influence of near-term environmental condition on the growth of juvenile coho salmon (Oncorhynchus kisutch). It includes the inputs necessary for bioenergetic growth modeling and the output of those models.

Juvenile coho salmon seek slow velocity areas as rivers rise during storm events. Studies have shown significant increase in juvenile coho salmon growth and survival when they have access to slow water refuge in off-channel ponds during these storms. In addition, off channel features also provide habitat for several other animals including reptiles, amphibians and numerous bird species. In 2014, Humboldt Redwood Company (HRC) identified an abandoned overflow channel that had the potential to become off channel habitat in Lawrence Creek located within the Van Duzen River watershed and asked the National Marine Fisheries Service (NMFS) to partner on the project. NMFS conducted the physical surveys, created the design, and a small competitive internal grant from NOAA provided funding for part of the project construction. HRC worked on the permits, donated heavy equipment and operators as well as several large logs with root wads to build the instream structures.
