I have had a project on the back burner for a few years to measure how many miles of each type of shoreline there are on Lake Maxinkuckee.  Fortunately, I was able to put our summer intern, Mia Wagner, on that project last summer. 

The first step was to determine what our classification types would be.  We settled on three: Concrete/Hard Seawall, Glacial Stone Seawall (80% of stone has to be basketball size stone or smaller), and Natural/Undeveloped.

Poor Shoreline Habitat Means Poor Lake Health

Hard seawalls:

  • cause scouring of the lake bottom and erosion of neighboring properties
  • cause sediment and nutrient suspension, and cumulatively lower water quality
  • do not support aquatic and shoreline vegetation growth
  • have no habitat complexity or ecological value
  • create a barrier for animal movement

The effects of individual shoreline developments on the nearshore lake environment accumulate over time, affecting fish, amphibians, birds, and other wildlife.

Results

57% Hard/Concrete
25% Glacial Stone
18% Natural/Undeveloped

Knowing these numbers is another tool in our toolbox in fulfilling our mission of Keeping Our Lake Healthy.

Why is this Information Important?

Natural shorelines benefit the lake in many ways.  Now we know that only 18% of the lake’s shoreline is dedicated to this classification.  For the overall long-term health of the lake, we can work towards increasing the miles of natural shoreline and/or glacial stone shorelines and decreasing the miles of concreate seawalls.  Determining if this is a priority and how to fund it will be a topic of discussion at future board meetings. 

The Watershed Foundation in Kosciusko County has a great Healthy Shorelines program that has been very successful.
