Completed in 1975, the Lower Granite Dam is located upstream of Lake Bryant. Before embarking on renovation of the dam, the US Army Corps of Engineers (USACE) needed virtual site access (VSA) and point cloud data, which Epic Scan provided along with accurate as-built information on present dam conditions.
