Beaver Water District (BWD) is a water district created in 1957 as a quasi-governmental agency to provide treated drinking water to the communities of Northwest Arkansas. The district's source is Beaver Lake, an impoundment of the White River created by Beaver Dam. The district wholesales treated potable water to Bentonville, Fayetteville, Rogers and Springdale, who then re-sell the water to their residential/commercial customers and smaller nearby communities.
