Monitoring of our restoration efforts is important to ensure specific project success as well as to guide future restoration priorities and project designs.  Through this program we are developing monitoring protocols and tools as well as disseminating the monitoring results in peer reviewed reports.

Our organization is completing scientific monitoring of watershed health benefits that result from our projects.  This involves both careful planning, in order to collect the baseline data before a project is completed, and dedication and follow-through in order to collect data over a time frame through which project responses can be measured.

Willanch Creek Stream Temperature Reduction

Although much of the monitoring we do will require long term investigation before it will be possible to properly evaluate many of our implemented projects, we are seeing some successes in places where we have multiple years of data.  On Willanch Creek, we have recorded a 10º F drop in 7-day maximum average summer water temperatures at the bottom of the project site.  There are numerous stream crossings that were lacking fish passage where we had previously observed coho utilization.  Several years of data subsequent to the upgrades show coho utilizing the newly opened areas.
