  The SCIWC is continually upgrading and maintaining facilities along the St. Croix watershed and volunteers are greatly appreciated.

Are you interested in: 

  • keeping the lakes and rivers clean

  • planting trees

  • upgrading trails, portages and campsites

  • learning about invasive species and how to identify them

  • water quality monitoring

  • teaching others about the natural, historical, and cultural qualities of the St. Croix?

If so, we'd love to hear from you!
