Floating Wetlands in Lake Herrick

Sarah Hensey, an undergraduate student, along with Aaron Trimble, Cody Matteson, and Jordan Noell Francis received a $5000 UGA Sustainability grant to design and install floating wetlands in Lake Herrick. Floating wetlands are a natural way to filter excess nutrients. The wetlands are made of a buoyant material and anchored to the lake bottom. Swamp sunflower, irises, river oats, and white star sedge are planted on the islands to filter out nutrients from the water; the plants should also attract beneficial microbes to reduce harmful bacteria in the lake. They were installed April 1st near the bridge in Lake Herrick with the help of student and faculty volunteers. They were placed near stream inflows in an attempt to filter out some excess nutrients from storm water runoff before the nutrients could make it to the rest of the lake. Right now the student team is working on getting the plants established and also continuing to monitor water quality parameters in Lake Herrick.
