Excerpt from: The Paradise Lake Case Study for Milfoil Control
Prepared by: Jennifer L. Jermalowicz Jones, Water Resources Director Restorative Lake Sciences
Paradise Lake is located in Emmet and Cheboygan Counties [Michigan]. The lake surface area is approximately 1,878 acres and it has a maximum and average depth of 15.1 feet and 3.9 feet, respectively. The shoreline length is about 14.3 miles and the watershed is approximately 16,685 acres, which is nearly nine times larger than the lake.
In recent years, the lake has become colonized with Zebra Mussels (Dreissena polymorpha), which has resulted in increased light transparency of the lake water and has cause accelerated growth rates of all aquatic vegetation, including the exotic submersed aquatic plant, Eurasian Watermilfoil.
Milfoil Reduction from Laminar Flow Aeration and Bio Augmentation
A primary objective of the laminar flow aeration system is to reduce the organic matter layer in the sediment so that a significant amount of nutrient is removed from the sediments and excessive muck is removed to yield a greater water depth or more desirable substrate. Additionally, scientists have discovered that the use of this aeration technology along with microbial supplementation [bioaugmentation] can effectively reduce ammonia nitrogen, which is an essential nutrient for some rooted, submersed aquatic plants such as milfoil.
