Highland GLEON buoy deployed for the season!


Maggie and Ben deployed the automated buoy on Highland Lake this week, and the Long Lake buoy is close behind! These automated buoys send info to the Science Center every fifteen minutes during the testing season. Sensors hanging through the water column under the buoy and others on the buoy measure temperature, clarity, oxygen, chlorophyll, and weather levels and help us to gather a significant data set to help us better understand how vulnerable our lakes are to algae blooms and factors that affect them. The buoys are part of the Global Lake Ecology Observation Network (GLEON), a collection of lake monitoring sites located all over the world. Check out for more information about the network, and stay tuned for more sharing of data from the buoys!

The Portland Water District regularly deploys a buoy on Sebago Lake; you can find more info about their buoy here.
