The Fish Passage Inventory, Assessment, and Prioritization Manual provides standardized guidance for assessing structures that potentially block adult salmonid passage, and identifying surface water diversion deficiencies. It also provides an established protocol for prioritizing barrier corrections. These protocols are widely utilized and accepted, and provide a consistent approach to evaluating fish passage barriers statewide.

Supplementary materials
Level B Hydraulic Analysis Spreadsheet (XLSX) - This spreadsheet includes all of the fields required to perform the analysis, but does not perform Level B calculations. Complete the spreadsheet (pay particular attention to the first two tabs), then email it to FishPassageInventory@dfw.wa.gov. WDFW staff will perform the Level B analysis and return the results to you. Please reference the Inventory Manual (Chapter 3) for descriptions of the required fields.
Physical Habitat Survey (XLSX) - Input File (V.5) - This workbook is used to document habitat surveys and calculate habitat gain upstream of fish passage barriers. There are separate sheets for data input, data output, fish access check notes, and upstream habitat notes. Please reference the Inventory Manual (Chapters 10 and 11) for descriptions of the fields. Please email FishPassageInventory@dfw.wa.gov with any data entry questions.
