This map shows information on the location, type, and fish passage barrier status of road-based stream crossing structures, dams, and miscellaneous instream structures in Washington State. It is a subset of data extracted from the Washington Department of Fish and Wildlife's (WDFW) Fish Passage and Diversion Screening Inventory (FPDSI) database. It includes data compiled from several WDFW and non-WDFW fish passage barrier inventory efforts. The data are statewide in scope but do not represent a comprehensive or complete inventory of fish passage barriers. The data set is updated continually as inventory efforts are ongoing. The data are used to identify, locate, and prioritize correction of man-made fish passage barriers. Identifying and correcting fish passage barriers is a key component of salmon recovery. The data may be used by any group interested in salmon and habitat recovery. The data are also used to track where inventory efforts have occurred. The Washington Department of Fish and Wildlife (WDFW) makes no guarantee concerning the data's content, accuracy, completeness, or the results obtained from queries or use of these data. WDFW makes no warranty of fitness for a particular purpose, no representation as to the quality of any data, and assumes no liability for the data represented here. These data do not represent exhaustive inventories, but are compilations of existing knowledge from field biologists that are updated periodically as knowledge improves. This data should be used cautiously because they are not exhaustive, and are subject to change. When conducting projects or planning for fish and wildlife, please consider using additional information gathered from field investigations and consultations with WDFW or other professional biologists.
