The St. Croix River and its major tributary, the Namekagon, were among the first four designated Wild and Scenic Rivers in 1968. A canoe on the Namekagon and upper St. Croix passes through northern conifer and hardwood forests, extensive marshes, and wild rice beds. The lower St. Croix is home to unique collections of native mussels.

As a foundational part of the aquatic food web, dragonfly larvae we collect each summer are tested for mercury in the environment, which helps us understand mercury contamination at higher levels of the food web.
