Cyanobacteria blooms reported in Lake Massapoag

Localized cyanobacteria (blue-green algae) blooms continue to be reported in Lake Massapoag with blue-green flecks seen in the water column away from the shore and green scum washing up near the shore (north, south, east and west). The green material can be transient, as it moves with the wind.

The amount of cyanobacteria does not currently warrant a public health advisory, but there are steps the public should take, according to the Lake Massapoag Advisory Committee.

If you see a green scum, sheen or flecks in the water, do not swim or let pets in the water and go to another location until it clears.

Report significant sightings to the Board of Health at lmclean@townofsharon.org, Conservation Department at jphilibert@townofsharon.org or Lake Massapoag Advisory Committee lakecom@townofsharon.org.
