The ICPRB provides various maps for public use. Maps are an integral part of understanding the watershed and encouraging stewardship. We offer various maps for different uses, including for recreation, defining watershed boundaries, and providing interactive watershed maps to learn more about your home watershed. Some of the maps are downloadable as PDF files and are formatted for printing on 8.5"x11" paper.
