Petenwell & Castle Rock Stewards


PACRS is a tax exempt, nonprofit organization that coordinates and facilitates a diverse group of people focused on improving the water quality and recreation on the Petenwell and Castle Rock lakes of the Wisconsin River.

About Us


The PACRS organized in 2007 to address water quality issues on the lakes in the Wisconsin River watershed.  Working together with citizen’s groups, municipalities, DNR, Wisconsin River Power Company and elected officials will make a positive change.  In order for this to take place, it is very necessary that trust and partnership be the cornerstone of any relationship.  Working together becomes the way, not the exception.  Trust and partnership play a significant role in our accomplishments and projects.
