Our Challenge

Grand Lake St. Marys (GLSM) and its watershed have a long history of trials and tribulations. According to folklore, during the construction of GLSM, there was such controversy over people getting malaria from the flooded waters that citizens busted through the west bank dam. Today, GLSM is still taking the blame for possible health risks. Algae blooms, which have the potential to produce harmful toxins, have been located in GLSM. These blooms feed off of nutrients from non-point source pollution. Everyone who comes in contact with the GLSM watershed, the area that drains into the lake, has a part in the health and reduction of algae blooms in GLSM.

It's up to you and me to reduce our contribution to nonpoint source pollution. It may seem like a drop in the bucket, but those drops add up!
