Schoolhouse Pond in Hyannisport has a solar powered water circulator working to reduce toxic blooms. In the summers of 2013-2015 the pond was closed to recreational use, because of severely reduced water clarity and cyanobacteria toxins.
The Town and Medora Corporation with the help of the Friends of Schoolhouse Pond installed a Solarbee June 2016, which already appears to be helping the pond ecosystem.
