Abstract

"Public swimming beaches at the Lake of the Ozarks State Park (LOSP) are popular vacationing spots for many Missourians; however, on several occasions Escherichia coli (E. coli) concentrations have exceeded standards set by the Missouri Department of Natural Resources (MDNR). Exceedances lead to beach closures which not only represent a potential public health threat but are also detrimental to the local economy and the public's perception of the lake's general water quality. In a collaborative effort between Missouri S&T, the United States Geological Survey (USGS) and the MDNR, an in-depth, two-summer study was conducted which included collection of over 1,300 water and sediment samples at 36 locations, sediment resuspension, runoff analysis and microbial source tracking (MST) studies.

Coupling spatial, temporal and microbial source tracking studies, predominant sources of E. coli contamination at Lake of the Ozarks State Park identified during this study were the fecal contamination from waterfowl harbored in beach sediments and from tributary inflow. Once concentrated in sediments, E. coli are likely suspended into the water column by bathers and slowly decay and potentially advect out of Grand Glaize Beach Cove. Modifications to beach and waterfowl management along with routine lake-wide sampling will likely alleviate E. coli contamination at Grand Glaize Beach and improve public perception of general lake quality"--Abstract, page iv.
