Our Purpose

Harbor Watch was founded in 1986 to improve water quality and ecosystem health in Connecticut. We are scientists who provide the data, knowledge, and field expertise needed to safeguard Connecticut waterways, educate our community about watershed issues, and train volunteers and student interns through hands-on research.
