2025 Priority Fish Passage Barrier List

ODFW has updated the Statewide Priority Barrier List (Priority List) with a new version, published in 2025. During this update, methods for ranking the barriers on the list were modified to include two new factors to consider climate change during scoring (current cold-water access and predicted change in thermal suitability). The Priority List identifies the most critical artificial barriers to fish passage in Oregon, ranking them based on the amount and quality of habitat blocked, current level of passage, number of species impacted, and other factors, including the predicted effects of climate change. This list is used to help direct restoration and enforcement efforts throughout Oregon.
