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.

The map application linked below shows human-made barriers where a fish passage barrier inventory has been conducted. The GIS data is also available to download at:

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.
