A key to long-term lake management is nutrient reduction. Focusing on watershed management is critically important as well. However, most lakes receive even more nutrients from the release of nutrients already in the lake sediments than from nutrients brought into the lake.
Engineering aeration combined with bacteria and enzyme treatment of organic sediment has shown to be an effective, economically feasible approach to controlling the release of nutrients from sediments into the water column. This approach can deliver significant improvement in overall water quality and lake health.
During 2012 a contractor will be selected and plans will be completed to begin the four-year pilot in 2013. The pilot area will be the northeast section of the lake (Sherwood Bay) where weed growth is especially dense and organic sediment is quite thick. Equipment will be installed in spring 2013.
