Damariscotta Lake’s Second Confirmed Hydrilla Infestation
Boaters on Damariscotta Lake traveling upstream along the Davis Stream may be confronted with a navigational buoy reading “Area Closed”. Backed by a state order, the message is intended to ensure that boaters do not disturb and further spread an infestation of the invasive aquatic weed Hydrilla.

This is Damariscotta Lake’s second confirmed hydrilla infestation. The first infestation has been successfully sealed off from the rest of the lake in an isolated lagoon and extensive lakeshore surveys have revealed no further infestation sites to date.

Hydrilla, a non-native aggressive aquatic plant can clog boating channels and degrade fish and wildlife habitat. Once established it can grow uncontrollably quickly shading out native plants and vegetation.

Georgica Pond Opened for Shellfishing after Toxic Blue-Green Algae - Last year, the Friends of Georgica Pond Foundation leased an aquatic weed harvester to remove macroalgae from the pond. As it decays, the macroalgae provides nutrients to harmful algae such as cyanobacteria. The removal last summer of more than 55,000 pounds of macroalgae is believed to be responsible for a substantial reduction in the levels of cyanobacteria recorded last year, and may be a factor in the relatively brief bloom that occurred last month.
