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.
