A Decade of Improving Habitat Access for Fish

The Oregon Watershed Restoration Inventory (OWRI) houses restoration data for the state of Oregon and is managed by the Oregon Watershed Enhancement Board (OWEB).  Information provided to the OWRI is used to report on The Oregon Plan for Salmon and Watersheds accomplishments, support effectiveness monitoring of restoration activities, and support watershed assessments and future restoration project planning and prioritization.  
Over the last decade (1998-2008), OWEB has found that fish passage improvement projects rank among the most numerous of the restoration actions implemented throughout the state.   The main objective for fish passage improvement is to re-connect fish to stream habitat that has been made inaccessible through road building activities and other land uses.  This restoration action can provide an almost immediate benefit to fish populations by expanding spawning and rearing areas, in many cases, at the completion of a project.  This viewer portrays stream habitat made accessible to salmon, in addition to other species of native fish and wildlife, after a decade of fish passage improvement actions, as reported to the OWRI.
The John Day basin and Coos sub-basin were initially chosen because they are representative of the restoration work that is completed across the state.  Both basins have a large number of historical barriers, significant populations of salmon, and also have made significant progress in the number of stream miles improved for habitat access.  The goal of fish passage improvement projects is to increase the ability of fish to access and use habitat - ranging from habitat that was previously inaccessible to all fish to habitat that could not be accessed by fish at certain life stages (e.g., small juvenile fish).
