Delegates from each participating school attend the annual Student GREEN Congress held in March of each year. The Congress is held at the Evergreen State College and in partnership with the Nisqually River Education Project.

Students participate in State of the Rivers Sessions, where they present and discuss thier findings. They identify data which exceed optimal water quality standards, discuss possible causes of pollution or poor conditions, and make recommendations for improving the health of the watershed.

Students attend workshops in the afternoon to learn new skills and information about the environment.  Descriptions of last year's workshops can be found here.
