The federal government and the states of Oregon and Washington have all developed recovery plans for endangered and threatened Columbia River salmon. The Estuary Partnership has obtained some of the GIS data contained in these plans, and presented it in the map below to help inform restoration and recovery efforts. As more data becomes available it will be added to the map. Currently, the following datasets are included:

Our juvenile chinook salmon habitat suitability index (HSI) model, developed in 2010 by Batelle's Pacific Northwest National Laboratory Marine Sciences Lab, with funding provided by the EPA, combines water temperature, depth, and current velocity information to predict locations that provide suitable in-water habitat for lower Columbia River juvenile Chinook salmon. Suitability thresholds for each of these criteria were adopted from previous studies on juvenile Chinook salmon.

The Estuary Partnership's approach to habitat restoration is guided by the framework of our Comprehensive Conservation and Management Plan, which calls for restoring the lower Columbia River's biological integrity and ecosystem structure and function. The lower River and it's estuary historically supported diverse and abundant populations of fish and wildlife, including some of the world's largest stocks of Pacific salmonid species. Anthropogenic changes dating back to the 1800s have significantly reduced the quantity and quality of habitat available to fish and wildlife species. Our habitat
