Important UPDATE:

In the Fall of 2025, CPWA representatives met with the Town to present our ideas to mitigate the Cyanbacteria blooms that have plagued Clear Pond for the past few summers; at the time the Town indicated that treating the pond with alum, to treat excess phosporous, would be favorably promoted provided that we had neighborhood support. We reached out to abutters to the pond and received positive support. Sadly, further examination of past test results indicate that the biggest issue with the pond is excess Nitrogen, not Phosporous. Alum does not treat nitrogen, so we will re-group to work on Plan B.

Fortunately, the environmental engineer that has very generously been assisting us in our efforts is scheduled to be at our next meeting on May 12 at 7pm at the Plymouth Library. We will be able to ask him questions about the next steps we can take to help mitigate the cyanobacteria blooms.

In the meantime, the Clear Pond Water Association will continue to assist the town with seasonal water testing; as well, we are participating in collaborative efforts with other local groups for the betterment of ponds throughout Plymouth.

Some other CPWA projects are in their infancy; one such project is to target the removal of non-native plants, which can adversely affect water quality. There are still many details to work out, so stay tuned!

Clear Pond Water Association, Inc. (CPWA) is a registered 501(c)(3) not-for-profit organization created to protect, maintain, and enhance the waters of Clear Pond. CPWA has been established by a group of concerned neighbors surrounding Clear Pond. 

Our mission is:

• To protect Clear Pond for current and future generations

• To build and support responsible stewardship of our fragile ecosystems

• To be a resource for environmental education critical to the health and enjoyment of Clear Pond

• To be a voice with local and state authorities for support of the Association’s initiative

CPWA encourages residents to take an active interest in the health of Clear Pond, restore and protect the Pond’s habitats, and improve water quality by taking action to understand, eliminate and prevent pollution.

Clear Pond is 13.6 acres of spring-fed water that for the past several  years has been closed for most if not all of the summer season due to cyanobacteria blooms, a blue-green algae which can be harmful to people and animals.  Sometimes this bloom occurs below the water and you cannot see it.  Fertilizer runoff, septic tank overflow, and seepage from the old cranberry bog contribute to conditions favorable for a bloom.

We post our meeting schedule on the homepage…we would love to meet more of our neighbors!
