Fish Passage Program
Washington State Fish Passage Map Application
WDFW maintains a centralized database of fish passage, diversion screening, fish use, and habitat information from inventory
efforts conducted throughout Washington State. WDFW’s Fish Passage and Diversion Screening Inventory (FPDSI) database is a
main data source for planning fish passage projects.
Update barrier information
You can also update barrier information through this interactive map. Use the Fish Passage Data Edit Tool under the search bar
to report new sites, update existing ones, or let us know of corrections to barriers. Data may be verified by field staff prior
to changes being reflected in the map. Your input helps us tell the statewide fish passage story and is appreciated.
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 human-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. 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.
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. This information is typically updated every 6
months and therefore, updates to the map may not be seen immediately.
