World O! Water is a fun, annual event for people of all ages to learn about the important role that water plays in our lives and community. Join us this year on September 10th to experience live demonstrations, science experiments, games, and canoe rides while talking to local experts about water quality, conservation, and recreational activities. Your family, youth group, scout troop, school class, and even your dog, is welcome to attend this free event held at Wehrspann Lake inside the Chalco Hills Recreation Area.
