State reports high toxins in Canandaigua, Keuka lakes from algae

State Department of Environmental Conservation reports lab samples this week confirmed high toxins from blue-green algae in Canandaigua and Keuka lakes. This week, the DEC added 16 waterbodies to the notification list. There are currently 65 waterbodies statewide with blooms on the list.

Kevin Olvany, Canandaigua Lake Watershed program manager, had reported that results from three samples collected Monday showed high toxins. Mid-week, it appeared the vast majority of the lake was not experiencing bloom level conditions. Instead, blooms tended to be located along sections of shoreline and near shore areas where the gentle wind caused algae to concentrate.

Conditions can change quickly on the lake.

“This warm, sunny and calm weather continues to provide potential excellent growing conditions for algae. Conditions can change quickly on the lake, so we cannot say where blue green algae will be present and whether it will reach bloom conditions in a specific location. During very calm conditions blooms can potentially generate at the surface in the mid-lake areas as well,” Olvany reported.
