Seneca Lake Pure Waters Association is a 501(c)3 organization committed to preserving, protecting, and promoting the abundant resources of the largest Finger Lake. Seneca Lake is a source of drinking water, recreation, and economic opportunity for the greater community and its visitors. Our programs and partnerships make it possible to monitor water quality, educate the public, and evaluate threats to ensure the a healthy future for Seneca Lake and those who depend on it.


Three main pillars allow Seneca Lake PURE WATERS Association to deliver on it's mission.


Volunteers are the core of the Pure Waters organization.  The data they obtain supports research and fact based decision-making for municipal leaders, stakeholders, and individuals around the lake.  We rely on volunteers' talent and skills, from citizen scientists monitoring our waters to the teamwork of committee members and program coordinators.

Pure Waters depends on the coordinated collaboration of many critical partners to execute watershed research, programming, and water quality improvements.  These partners include lake associations, local and state governments, and educational and non-profit organizations.

Out educational efforts inform residents, businesses, and visitors on Seneca Lake water quality and ways to contribute to its improvement.  Education takes many forms.  Examples include water quality Public Forums and Research Conferences, Harmful Algal Bloom alerts and other publications, website/social media outreach, and conversations with association members.
