“How many fish will this restoration project produce?” It is a question restoration professionals get asked all the time, and it is one that is very difficult to answer. However, we may be closer than ever to showing how restoration projects affect fish populations thanks to the Mill Creek (Siletz) restoration and effectiveness monitoring project.
The MidCoast Watersheds Council invites the public to attend a presentation by Chris Lorion, Assistant Project Leader for the Salmonid Life Cycle Monitoring Project with the Oregon Department of Fish and Wildlife (ODFW), on Thursday August 3rd, 2017 at 6:30 PM in Newport. The talk will be held in room 205 at the Newport Visual Arts Center at Nye Beach. Refreshments will be served.
The Mill Creek Restoration and Effectiveness Monitoring project was funded by the Oregon Watershed Enhancement Board. It is a collaboration between the MidCoast Watersheds Council, ODFW, Oregon State University, Oregon Dept. of Environmental Quality, Weyerhaeuser, Lincoln Soil and Water Conservation District and the Confederated Tribes of the Siletz Indians. The restoration work addressed the limiting factors of stream complexity and winter rearing habitat for coho in Mill Creek. Over 700 large logs were placed in Mill Creek and its tributaries to capture gravel, aggrade the stream bed, create back eddies and provide protection for young fish. The effectiveness monitoring part of the project builds on the past work of ODFW in this basin. Mill Creek is one of seven Salmonid Life Cycle Monitoring (LCM) sites managed by ODFW on the central Oregon coast. These sites estimate abundance of salmonids and downstream migrating juvenile salmonids, estimate marine and freshwater survival rates for coho, and evaluate effects of habitat modification on the abundance of juvenile salmonids. Due to the existing monitoring history, there was the opportunity to evaluate effects of large wood placement on stream habitat and fish populations.
Chris Lorion has worked as the assistant project leader for ODFW for 9 years, coordinating the ODFW Salmonid Life Cycle Monitoring Project. . Before that, Chris earned a Bachelor’s degree in Fisheries Science from Oregon State University and a Doctorate in Natural Resources from the University of Idaho and the Tropical Agricultural Research and Higher Education Center in Costa Rica. Over the past 20 years, Chris has worked on fish research projects investigating a wide variety of species, ranging from lampreys and cutthroat trout in Oregon to cichlids and tetras in tropical streams.
