Otisco Lake is a beautiful lake.
Help us to be better stewards of our watershed.
The Otisco Lake Preservation Association is a non-profit 501(c)(3) organization with a mission to preserve the health, beauty, and welfare of Otisco Lake – not only today, but for future generations.
In partnership with the Onondaga County Health Department, Onondaga County Water Authority (OCWA), and Cornell Cooperative Extension, we work to maintain the integrity of Otisco Lake and its watershed. We continue to fight the battle against Eurasian milfoil weed and other invasive species and have plans to utilize various options, along with providing educational literature, to help control and maintain these species in an effort to prevent further spreading and to protect our lake.
Otisco Lake is one of Onondaga County's main drinking water sources. We feel it is vital to everyone that we work together to safeguard this precious resource. We offer educational and awareness opportunities to help the community know how they can help. We are very involved in preserving and protecting our lake, its watershed, the health of our communities and our environment.
This website has been created by the OLPA to provide updates on the activities, events, and information that affect Otisco Lake. Please feel free to attend our monthly meetings which are held on the first Wednesday of the month at the Amber Inn, Marietta at 6:30 pm. We look forward to seeing you.
Help us preserve one of Central New York's most appreciated treasures! We promote protection of the Otisco Lake Watershed through the Otisco Lake Preservation Association (OLPA). Please support OPLA to keep Otisco Lake a primary source of Onondaga County pristine drinking water!
