Developments and other disturbances in watersheds can have a profound effect on the quality and/or quantity of available water. For this reason, it is crucial to protect these areas, regardless of whether a community uses surface or groundwater as its water supply source. According to a recent survey, 45 percent of the B.C. communities who responded have a watershed protection plan in place. The City of Chilliwack is one of the communities working to protect its watershed.
