StreamNet's Potential Fish Passage Barrier dataset captures both natural and man-made in stream features that have the potential to block fish passage (culverts, dams, debris jams, cascades, falls, etc.). Where information exists, fish passage ability is captured. This dataset is maintained and updated on an annual or semi-annual basis. The JUNE, 2012 publication dataset includes almost 60,000 features across the states of Washington, Oregon, Idaho, western Montana and California. Where possible, all barrier locations are georeferenced to StreamNet's regionally standardized routed hydrography layer (MSHv3) enabling comparison and analysis of barrier locations within the context of StreamNet's larger data holdings...

The Great Lakes Aquatic Habitat Connectivity Collaborative (AHC Collaborative) is working to develop best practices for aquatic connectivity project selection. Over the past decade, a suite of spatial desktop decision support tools has been developed for the Great Lakes region to aid in planning and selection of barrier (i.e. culverts or dams impeding aquatic organism passage) removal or rehabilitation. These tools are, for the most part, under-utilized by decision makers, likely because they do not know the tools exist, where to find them, how to use them, or how they perform in supporting “real life” decisions. We propose to examine the performance of both local, empirical data sets and existing decision support...

The Oregon Fish Passage Barrier Data Standard (OFPBDS) dataset contains barriers to fish passage in Oregon watercourses. Barriers include the following types of natural or artificial structures: bridges, cascades, culverts, dams, debris jams, fords, natural falls, tide gates, and weirs. The OFPBDS dataset does not include structures which are not associated with in-stream features (such as dikes, levees or berms). Barriers are structures which do, or potentially may, impede fish movement and migration. Barriers can be known to cause complete or partial blockage to fish passage, or they can be completely passable, or they may have an unknown passage status. The third publication of the OFPBDS dataset (Version 3)...
