Bacteria Water Quality Data Analysis and Interpretation, Glen Canyon National Recreation Area

U.S. National Park Service, U.S. National Park Service


Since 1988, Glen Canyon National Recreation Area has been monitoring bacteria levels in Lake Powell to assess potential impacts from recreational bathing and boating. Owing to high bacteria levels, advisory notices were posted at several beaches. The park requested that the Water Resources Division analyze and interpret the bacteria data, and help them develop a way to measure acute levels of bacterial contamination in time to warn recreational users.
