HERMATIGE, Mo. - The U.S. Army Corps of Engineers at Pomme de Terre Lake is responding to a toxic blue-green algae bloom with site-specific sampling and posting public health advisory signs around the lake as recommended by state health agencies.
On May 31, potentially toxic blue-green algae blooms were observed from Lindley Creek Arm mile marker L8 to the dam. Laboratory results from sample(s) from Lindley Creek Arm mile L5.5 area indicate the dense algae bloom consisted of 98% blue-green algae with algal toxin (microcystin) concentration below the Missouri Department of Natural Resources Public Health Warning Criteria for recreation contact but could be considered dangerous for pets. Considering these results, USACE is closing Nemo Park beach and general caution signs will be posted at access point and boat ramps for public awareness.
