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.
