The Pierce Conservation District completed an inventory of fish passage barriers in the andromous zone of East WRIA 15. Over 140 structures were identified, with 56% of those determined to be barriers to fish passage. This project prioritized those barriers, so higher priority projects can be adressed first. Prioritization was conducted following WDFW protocol as described in the Fish Passage Barrier Assessment and Prioritization Manual, and involved completing a field habitat survey of stream reaches above fish passage barriers to determine the quantity and quality of available habitat. Prioritization also considered species utilization, stock status for species utilizing the stream, and project cost. The resulting Priority Index (PI) score was used to directly compare priorities of proposed projects. After prioritization was completed, the top five barrier culverts were addressed and preliminary design work will be completed. The prioritized list was made available for Enhancement Groups, Conservation Districts, Cities, Counties, and other entities to use as a project list from which to work.
