Over the years, organic sediments built up in the lower end of Lake St. Catherine (181 acre Little Lake), Wells, VT. Milfoil growth started to dominate the lake and made navigation and water sport enjoyment almost impossible. Chemical applications to kill the milfoil contributed to further accumulations of over 20 feet of organic sediment. The lack of water depth due to organic muck accumulation and extensive milfoil growth started to impact everyone around the lake.
In 2010 the Lake St. Catherine Conservation Fund contacted CLEAN-FLO for help. After several meetings with the general public and State officials, a permit was issued in 2012 to install a CLEAN-FLO inversion oxygenation system in only a small section (≈ 14 acres) on the east side of the lake. The state required a water sampling regimen be implemented to prove that the system was not adversely impacting the water quality.
The system was installed in late summer 2012 and operated for about 2 months and then shut down for winter. In 2013 and 2014 the system was started in the spring and shut down in the fall, operating a total of about 12-13 months. During these 3 years, the Conservation Fund documented results through water testing, water measurements, and video. In 2014, 4 additional diffusers were added to the system and the area of aeration increased by about 4 acres. Here are some photos from before the system was installed.
