Daily Sentinel writer William “Bill” Nelson talks about the history of the Grand Valley irrigation system during the early days of Mesa County. Nelson describes how water projects were developed, how water is doled out to people in the area, and specific water rights. He also discusses his family life, community activism, his father’s failing businesses during the Great Depression, and experiencing surgery on his retina. The interview was conducted by the Mesa County Oral History Project, a collaboration of Mesa County Libraries, the Museums of Western Colorado and the Mesa County Historical Society.
