The Iowa Department of Natural Resources has continued a swimming advisory for Beeds Lake State Park. The park is located near Hampton.
According to officials, measurements of the water indicate a E. coli reading of 620 per 100 milliliters of water. The safe ceiling for swimming is 235 per 100 milliliters.
Officials have not closed the beach at the lake nor have they banned swimming in the lake. They do advise against ingesting water from the lake and to shower shortly after getting out of the water.
Some strains of E. coli have been found to cause urinary tract infections, gastroenteritis, and neonatal meningitis. Officials are trying to track down if the E. coli came from earlier sewer overflow drainage from spring flooding that made its way into the lake.
