If you have always wanted to know how we get our drinking water and the role of the Boise river in that process then a new River Campus at the Boise Water Shed will help you understand. The new area opens tomorrow (Saturday) and 10 am and this is a completely free event. Activities will continue until 1 pm and everyone is welcome. In addition to the interactive area there will also be hay rides and a tour of the facility. The water shed is located down the hill from Hewlett Packard on Joplin street.
