WSDOT Environmental Services Office, Stream Restoration ProgramThis GIS data shows the locations of WSDOT fish passage sites that are currently in design within the WSDOT fish passage project delivery plan. ( https://wsdot.wa.gov/construction-planning/protecting-environment/improving-fish-passage/fish-passage-project-delivery-plans ). The fish passage project delivery plan incorporates the Legislature's new revenue funding and communicates WSDOT's intentions for specific investments in transportation infrastructure. This GIS data is a subset of data compiled and 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 Fish Passage project delivery plans are subject to change due to significant project issues and/or new information.ArcGIS DynamicMapLayerhttps://hub.arcgis.com/datasets/31858f7511cd49138c34bf1b1e02b8a6_10engState of Washington Geospatial Open Data PortalPublicWSDOT - Fish Passage Delivery Plan Sites - In Design [Washington (State)]Web servicesWashington (State)Last Modified: 2026-01-06
