This data set contains 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 weekly as inventory efforts are ongoing. Please note that the "Date Updated" value of this item refers to the ArcGIS Online item's date, not the data contained within.

The Global Reservoir and Dam Database, Version 1, Revision 01 (v1.01) contains 6,862 records of reservoirs and their associated dams with a cumulative storage capacity of 6,197 cubic km. The dams were geospatially referenced and assigned to polygons depicting reservoir outlines at high spatial resolution. Dams have multiple attributes, such as name of the dam and impounded river, primary use, nearest city, height, area and volume of reservoir, and year of construction (or commissioning). While the main focus was to include all dams associated with reservoirs that have a storage capacity of more than 0.1 cubic kilometers, many smaller dams and reservoirs were added where data were available. The data were compiled by Lehner et al. (2011) and are distributed by the Global Water System Project (GWSP) and by the Columbia University Center for International Earth Science Information Network (CIESIN). For details please refer to the Technical Documentation which is provided with the data.The Global Reservoir and Dam Database, Version 1, Revision 01 (v1.01) contains 6,862 records of reservoirs and their associated dams with a cumulative storage capacity of 6,197 cubic km.

This GIS data shows locations across the state where WSDOT fish barrier corrections have been completed. Some of the WSDOT fish passage barriers that have been reported as replaced or retrofitted for fish passage may require additional work to meet current fish passage criteria. Corrected sites can become barriers due to physical deterioration of the fish passage structure itself or changes in the landscape and streambed.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.

This GIS data shows the locations of WSDOT fish passage sites in the 2023-2025 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.

This GIS data shows the locations of WSDOT fish passage barriers on the current injunction list. 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. This dataset is updated quarterly.

This GIS data shows the locations of WSDOT road crossings, including culverts, dams, bridges, and fishways.The GIS data contains attributes identifying location information in latitude and longitude, as well as state plane coordinates and state route and milepost. Additional attributes include indicators for fish use, barrier status, and fish species.
