Home PageState Parks Beach Status
The Missouri Department of Natural Resources has developed this map so Missourians can tell, at a glance, if a state park beach is open or closed, whether it's for bacterial issues, operational issues or flooding.
The department will also post sampling data taken by the U. S. Army Corps of Engineers (USACE) at two of its beach areas at Mark Twain Lake, which include Indian Creek Recreation Area and John F. Spalding Recreation Area.
Clicking on a flag will bring up the most recent sampling results for the beach. Please note that some parks have more than one beach, and you'll need to use the zoom tool towards the left side of the map to get close enough to see individual beaches.
Samples for state park beaches are taken the first of each week and processed and analyzed at DNR's Environmental Services Program laboratory in Jefferson City. Full beach data will be updated by 1 p.m. Friday, though some closure notifications may be made before that time, as results are available.
The Missouri Department of Natural Resources closes beaches when single samples exceed the EPA recommended maximum of 235 E. coli colonies per 100 milliliters of water (235 mpn/100ml) or when the geometric mean -- a rolling average of sample data -- exceeds 126 E. coli colonies per 100 milliliters of water (126 mpn/100ml).
