Cayuga Lake Watershed Intermunicipal Organization

All municipalities in the watershed are members of the Cayuga Lake Watershed Intermunicipal Organization (CWIO). To be a voting member, a government must pay its annual dues which are due by June 30 annually.

The Big Picture: Why Become a CWIO Member Municipality

New York State has tasked their municipal governments with protecting the health, safety, and welfare of the residents within their jurisdictions. The CWIO believes watershed protection and stewardship of Cayuga Lake, its tributaries and its wetlands are in the public interest and should be managed in trust for the common benefit of all within the watershed.

Watershed-wide organizations made up of local governments are able to facilitate partnerships across municipal boundaries to address threats to our water resources as a whole. Participating local governments gain the mutual advantage and efficiency of pooling resources and expertise to implement restoration and protection efforts throughout the watershed.

How CWIO Assists Local Governments

CWIO work includes a range of activities depending on current member needs, resources, and watershed-wide priorities. It includes:

  1. Advancing a regional perspective on watershed-wide protection goals and assisting members with identifying priorities.
  2. Supporting local governments to implement the Cayuga Lake Restoration and Protection Plan and other similar official watershed-wide plans.
  3. Exploring mutually beneficial ways of securing and sharing federal, state, and county agency grant funding to improve water quality within and between members.
  4. Providing a forum for local governments and agencies within the watershed to interact and exchange information.
  5. Supporting individual projects with shared expertise, in-kind support, information about funding, assistance with monitoring, maintenance and more.
  6. Raising awareness of watershed needs at the state level and advocating for resources.
  7. Pooling local government funds and resources to more efficiently achieve our common goals.

All governments within the watershed are members of the Cayuga Lake Watershed Intermunicipal Organization (CWIO). Those that pay their annual dues can vote on CWIO business and actions via their appointed representatives.

As stated in the Bylaws,

“Membership is open to counties, municipalities (villages, towns and cities) and indigenous nations located within the watershed (referred to as “member entities”).

To qualify to vote in CWIO decisions, the member entity (county, municipality, or indigenous nation) must have signed the CWIO Memorandum of Agreement (MOA) and have fully paid their annual dues. Only representatives or their alternates from voting member entities count as part of the quorum.”
