Annual Potter Lake Makeover Project Completed

Monday, August 13, 2018

LAWRENCE -- The University of Kansas contracted Underwater Solutions, LLC (Spirit Lake, Iowa), to assist with the removal of invasive aquatic vegetation, for example, water lilies, from Potter Lake.  This effort began on Monday, August 6, 2018 and was completed on Wednesday, August 8, 2018.  During this three-day operation, approximately 80 tons of aquatic vegetation was removed from the lake. The purpose of this project is to prevent and/or minimize eutrophication of the lake which can lead to excessive growth of algae and aquatic vegetation in the lake.

Each year, during the fall and winter months, this vegetation dies and settles to the bottom of the lake where it decomposes.  This decomposition results in the release of food (e.g., nitrogen and phosphorus) which accelerates the rate of eutrophication of Potter Lake which has resulted in unsightly algal blooms covering the surface of the lake in the past.

This plant removal effort is part of the University’s commitment to maintain and improve the environmental condition of Potter Lake as part of the overall environment of the campus.Harvesting machine removing vegetation
