Beach monitoring team  tested Thornapple Lake for the presence of  a harmful Algal Bloom (HAB) after observing a green film on the water in some areas of the lake.  Preliminary results indicate the water may contain harmful  Algal Bloom.  It is recommended the public avoid swimming and any contact with areas of the lake with green film or other signs of HAB.
