This app and associated layers of data are provided for the purpose of illustrating the challenges and complexity of work required to correct fish passage barriers under Washington State highways. The Washington State Department of Transportation (WSDOT) makes no guarantee concerning the data's content, accuracy, completeness, or the results obtained from queries or use of the data, including the underlying base maps. The data supporting this app are from the Washington State Department of Fish and Wildlife (WDFW). The data do not represent exhaustive inventories, but are compilations of knowledge from field biologists that are updated periodically as knowledge improves. It is important to note that habitats or species may occur on the ground in areas not currently known to those who prepared the data, or in areas for which comprehensive surveys have not been conducted. Site specific surveys are frequently necessary to rule out the presence of priority habitats or species. When planning or designing projects that may affect these sites, please consider using additional information gathered from field investigations and consultations with WSDOT, WDFW or other professional biologists.Application Contact Information: Garrett Fuelling, GIS Analyst ([email protected])Katrina Keleher, Fish Passage Data Steward ([email protected])
