CLEANING YOUR AQUARIUM, DELAVAN LAKE
I once had a 55 gallon aquarium full of fish and plants. It was very hard to keep clean because of the variables of temperature, light and pollutants. When we realize that Delavan Lake is an aquarium with approximately two billion gallons of water we can appreciate how hard it is to keep it clean.
Delavan Lake is subject to the variable of Mother Nature, but it is the human elements that cause the problems. We have to control the pollutants that flow into the lake in order to keep Delavan Lake useable for generations to come.
Brown's Channel was dredged in 2007 to reduce sediment that was polluting our lake. The wetland areas north of Mound Road were re-worked in 2008. This area filters the water entering Delavan Lake from Jackson Creek. The newly formed Delavan Lake Sanitary District/Kettle Moraine Land Trust partnership will be working to eliminate agricultural run-off and other contaminants that enter our lake from the streams that flow into Delavan Lake.
The next project that needs to be done in order to continue the clean-up of Delavan Lake is to dredge the Inlet. Almost half the water entering the lake comes through the inlet. If the water flowing under the bridge at Highway 50 is contaminated, the water in front of your property will be green and yucky.
Over the last 100 years, the Inlet area has filled in with sediment as the slow moving water has left chemicals and pollutants in the mud. As the Inlet became shallower the water now picks up that mud as it flows by and dumps the chemicals into the main area of the lake. These chemicals from the Inlet are the primary reason your lake turns green and unclear.
A channel dug through the Inlet will remove almost 4,000 truckloads of polluted sediment. It will also provide a deep track that will allow water to flow through without picking up the mud that pollutes our lake. More clean water, less mud, fewer chemicals and less green algae.
In February there will be public meetings explaining the benefits of dredging the Inlet. Hopefully, in March, the Town Board will approve this project and vote to preserve Delavan Lake for our families, our grandkids and their grandkids. The Delavan Lake Improvement Association will continue to work and push in an effort to be sure this project is completed.
