The restoration effectiveness monitoring program is comprised of 2 main monitoring projects, the Winter Lake Restoration Effectiveness Monitoring and the Lower Coquille Tide Gate and Fish Passage Monitoring projects.  Both are located in the freshwater estuary of the Coquille River.  The Winter Lake Restoration Effectiveness Monitoring is a 3-year project that monitors the new tide gate infrastructure and the 400 acre ODFW wetland and channel restoration project.   While the Lower Coquille Tide Gate and Fish Passage Monitoring (Lower Coquille Monitoring) encompasses 1 proposed and 3 upgraded tide gate and habitat restoration projects to determine how these types of projects can aid in the Oregon Coast Coho Recovery efforts.

Winter Lake Restoration Effectiveness Monitoring

This project monitors the largest tide gate replacement project along the Oregon Coast, pairing agricultural production with improved coho salmon overwintering habitat.  There are 14 different parameters being monitored to determine how the restoration project has impacted water quality and quantity and the response of salmonids to the tide gates and improved habitat.  You can find descriptions of all 14 parameters and a map on the Projects Element Table link below. 

The first two years of monitoring data has been synthesized and presented in the annual progress reports, link below.  As the project continues and more data is collected and analyzed future progress reports will be posted on this page.  This project is funded by OWEB grant # 218-2042-15946.

Lower Coquille Tide Gate and Fish Passage Monitoring

The overarching goal is to work collaboratively to examine not only the functionality of individual tide gate projects but how their compounded uplift promotes recovery of the Oregon Coast ESU coho and the Coquille fall Chinook population. It is important to complete this effectiveness monitoring at the forefront of the tide gate replacement movement that is growing along the Oregon Coast to ensure we are maximizing ecological benefits and return on investment.

The Lower Coquille Monitoring relies on an extensive fish trapping effort and the collaboration with multiple offices of ODFW.  The collaboration is imperative for the installation of Passive Integrated Transponder (PIT) antennas at the tide gates of Winter Lake, Seestrom, Cochran and Coaledo project sites, seining in the mainstem Coquille River and in-depth statistical analysis of the results.  A summary of the monitoring can be found in the LCTGFPM white paper.
