 Abstract:  In the past several years, the Missouri Department of Natural Resources has closed a popular public beach, Grand Glaize Beach (GGB), at Lake of the Ozarks State Park in Osage Beach, Missouri when monitoring results exceeded the established Escherichia coli (E. coli) standard. As a result of the beach closures, the U.S. Geological Survey, in cooperation with the Missouri Department of Natural Resources, and in collaboration with the Missouri University of Science and Technology, led an investigation into the occurrence and origins of E. coli at GGB. The study included the collection of more than 1,300 water, sediment, and fecal source samples between August 2011 and February 2013 from the beach and vicinity. Spatial and temporal patterns of E. coli concentrations in water and sediments combined with measurements of environmental variables and beach-use patterns were used to identify possible sources of E. coli contamination at the beach.

Results from a 2011 reconnaissance sampling indicate that water samples from GGB cove contained significantly larger E. coli concentrations than adjacent coves and were largest at sites at the upper end of GGB cove, indicating a probable local source of E. coli contamination within the upper end of the cove. Based on the findings of the 2011 study, sampling at GGB during 2012 included the collection of spatially and temporally distributed water, sediment, and re-suspended sediment samples. The final report will be released early March 2014.
