This project seeks to restore groundwater storage through beaver reintroduction in the Methow watershed. Between 2008-2014, the project has successfully reintroduced beavers to streams, resulting in 31 successful beaver colony sites. Beaver dams measurably affect rates of groundwater recharge and stream discharge. When beaver populations were reduced in the Northwen Hemisphere, the geomorphology and plant communities of small low-gradient streams changed significantly. At some sites where beavers have been successfully reintroduced, streamflow in some perennial streams has increased and previously intermittent streams are now observed to flow continuously. The increased groundwater storage is a source of added streamflow during the dry season. The project also involves conducting a peer reviewed study to quantify the stream temperature and stream flow benefit of beaver establishment.
