Harvester Removes 500 Tons of Weeds
Weed growth in St. Albans Bay was not as bad this past summer as anticipated according to Steve Cushing, President of the St. Albans Area Watershed Association (SAAWA).

Last year, high, turbid waters and a layer of sediment carried into the lake by flooding and rainfall reduced weed growth, explained Cushing. With clear water and low lake levels this summer, those familiar with the bay were expecting more weed growth than they’ve seen, but Cushing believes the sediment may also be helping to suppress weed growth this summer.

SAAWA removes 400 to 500 tons of weeds from the lake each summer with the help of an aquatic weed harvester. The weeds contain a lot of water, Cushing explained and once they dry out, 40 to 50 tons of organic matter remains. Removal of the weeds prevents the weeds from dying and decaying in the water where they would release phosphorus and nitrogen, the very nutrients that feed algae blooms.
