A freshwater biologist and educator, Rob Karner has helped to care for the Glen Lake Watershed in Leelanau County since 1977.
A retired teacher with degrees in zoology and biological sciences from Michigan State University, Rob is now the watershed biologist for the Glen Lakes Association. He also serves as chair of Leelanau Clean Water, a task for created by the Leelanau County Board of Commissioners. Through 15 years of sampling, Rob has observed an increasing delay in lake turnover – that is the mixing of shallow and deep waters that normally occurs in the fall. We talked with Rob at his home near Crystal River in the Glen Lake Watershed.
