BRIGHTON - Temperatures may be right for swimming, but the Iowa DNR has a “swimming not reccomended” label on Lake Darling.

As of Monday, July 13, the E. Coli level was too high for the department to label it safe to swim. E. Coli levels can be influenced by a number of things such as septic systems, manure spills, stormwater runoff, pet and wildlife droppings and rain.

As previously reported, Lake Darling had this same label on June 12.

An interactive map is available on the DNR website that shows the water quality monitoring on each of Iowa’s state parks. Currently Marble Beach in Spirit Lake and Lake Geode in Danville are closed for rennovations. So far, 11 of Iowa’s state parks have a “swimming not reccomended” label, according to the map.
