Learn about changes in water use and supply in the western United States in this NOVA Next article. During the Reclamation era—the 1930s to the 1970s—massive dams were built to provide water to the increasing population in the West.

Some critics argue that some new water projects are based on a misconception that you need more water to serve more people. Considering the limited water supply, water conservation may be the key to urban growth. Planning for the future of western water supplies involves the consideration of complex environmental and societal impacts and tradeoffs. This resource is part of the NOVA Next Collection.
