EGLE announces Inland Lake Shoreline Energy Assessment

New tool can aid designing of shoreline protection with minimal impact on lakes


The Michigan Department of Environment, Great Lakes, and Energy (EGLE) has developed a new assessment tool for assessing wave energy and erosion on inland lake shorelines. The Inland Lake Shoreline Energy Assessment standardizes evaluation of erosion and educates the public on important shoreline characteristics.

The assessment uses coastal engineering equations and current boating activity data, along with user-submitted information, to automatically provide an estimated wave height classification for the inland lake property of interest. Once the online assessment is submitted, a report is automatically emailed to the address provided. The report contains the estimated wave height classifications, pictures, and assessment responses on the energy that a site may experience.


One of the goals of creating this assessment is to assist in designing energy-appropriate shoreline protection that minimizes impacts to inland lakes. The report that is generated can be uploaded into the MiEnviro portal as part of inland lake shoreline protection permit applications and can be used by shoreline contractors, consultants, homeowners, and EGLE staff when designing or reviewing shoreline protection projects. The report can also be used to compare the energy level of inland lake properties or to compare a property to those included in EGLE’s Bioengineering Story Map.



The Inland Lake Shoreline Energy Assessment and the corresponding instructions can be accessed below.

The Inland Lake Shoreline Energy Assessment can be found, along with other inland lake and shoreline resources and information, on EGLE’s Shoreline Protection web page.
