Session Coordinator:

This session’s focus is modeling of salmonid habitats from an aquatic stream reach to full watershed scale.  Through the sharing of ideas and techniques we can further endeavors toward strengthening salmonid populations through the improvement of both the fish’s direct habitat and the surrounding area (riparian zone to the ridgeline) that all ultimately influence habitat conditions. Modeling efforts that help us further understand summer low flow conditions, mitigate winter flooding, reduce high summer stream temperatures, and improve cold-water refuges will be the focus of this session. A welcomed component will be any modeling techniques that possess the inclusion of climate change scenarios within the watershed evaluations to better understand and help mitigate how future climate conditions may impact the state of salmonid habitats. This session brings together people focused on modeling to share techniques and results to improve our understanding and enhance our watershed planning in hopes to maintain and improve critical salmonid habitat.
