NOAA’s National Marine Fisheries Service (NMFS) has developed multiple guidance documents to improve conditions for salmonids that must migrate past barriers to complete their life cycle. The documents provide criteria and additional guidelines for the design and operation of facilities at barriers (e.g., culverts, bridges, stream crossings, and tide gates) to fish migration and water intakes. The criteria were developed to create safe passage routes for adult and juvenile salmonids in rivers and streams and through reservoirs, restore habitat connectivity within watersheds, and enhance salmonid population productivity. The efficacy of any fish passage structure, device, facility, operation, or measure is highly dependent on local hydrology, target species and life stage, obstacle orientation relative to the stream, facility operation, and many other site-specific considerations including climate change. In this presentation we discuss the various NMFS fish passage guidance documents, how they are linked, their intersection with transportation infrastructure, and when it is appropriate to use the different documents. For example, in the West Coast Region (WCR), we recommend a project proponent familiarize themselves with the “NOAA Fisheries WCR Guidance to Improve the Resilience of Fish Passage Facilities to Climate Change” (Improving Resilience) guidance document. The Improving Resilience document outlines how to incorporate projected future flows the facility may experience over the life of the project and should be the starting point for the design process.
