- Ways to Give
The accepted norm on many of our lakes is to have a mowed lawn up to the edge of a concrete seawall. Concrete seawalls are not natural or healthy for our lakes. In fact, they disrupt the critical ribbon of life on lake shorelines, create added wave action, and stir up the bottom sediments. Sedimentation is the suspension of nutrients and material in our lakes, which is one of the main reasons for algae growth, green muck, and fish scarcity.
A ‘healthy shoreline’ has abundant plants both on the land and in the water. Glacial stone (or rock) seawalls are an improvement over concrete because they help slow wave action. Natural shorelines can also be stunning and easy to maintain without interfering with recreation.
How the lakes and streams in the area are viewed and treated is an evolving mentality. The Watershed Foundation works to catalyze healthy changes in the watershed through on-the-ground projects and education, improving and protecting lake quality for future generations.
The Rise and Fall of the Concrete Seawall
For some time, concrete seawalls and other harsh barriers were implemented in many of the lakes. These walls were inexpensive, easy to maintain, and added a barrier between the lakes and yards of residents. However, scientists soon discovered that the walls did much more than separate the lake from lawns. These man-made barriers replaced natural shorelines, decreasing plant life and animal habitat while escalating erosion and sedimentation in the lakes.
The success of the Healthy Shorelines Initiative was recognized with the 2013 Lake/ Watershed Implementation Project of the Year Award from the Indiana Lakes Management Society. In addition, The Watershed Foundation was the first group in Indiana to be honored by the National Fish Habitat Partnership as one of the 10 “Waters to Watch” across the country.
Concerned lake property owners who see the value in protecting the lakes make the completion of these projects possible. The immense public involvement is a valuable indicator that conditions are changing for the better on these lakes.
