It’s that time of year when blue-green algae starts to show up in Oklahoma lakes. Elevated levels of the potentially dangerous algae are being seen in several areas. Ross Adkins with the Army Corps of Engineers says informational signs are up, but swimming is not being restricted at this time. He says you do need to avoid the algae if you see it though.
Lake Tenkiller, Lake Texoma, and Lake Heyburn are areas where visible blooms have been sighted.
