摘要

The study uses an interdisciplinary approach to assess the economic efficiency ofwater allocations and fish habitat enhancements for chinook salmon and steelhead trout in the John Day River Basin, Oregon. Specific enhancements included water transfers to instream flow, habitat vegetation improvements, and habitat structural measures. The benefits of improved fish productivity included recreation and commercial uses. Streamflow and water temperature were found to be critical limiting factors in a majority of habitats. Low discharges posed limitations at sites where temperatures were elevated and at habitats where channel structure was simple. The economic efficiency of streamflow augmentation and habitat investments varied across sites.
