Cold Spring Harbor, New York
St. John's Pond has shaped this community for three centuries. Today, it needs us. The St. John's Pond Watershed Alliance is a 501(c)(3) nonprofit dedicated to its restoration and permanent stewardship.
"We stand at a threshold, not past one. Restoration is still possible — and action now prevents irreversible loss."

The Story
From its origins as St. John's Lake in the late 17th century, to the childhood memories of winter ice skating and spring fishing — this pond is woven into the fabric of Cold Spring Harbor life. It is a living ecosystem, a landmark, and a shared inheritance.
See what's at stakeThe Urgency
The wooden spillway weir at the heart of the dam — constructed in the early 20th century — is deteriorating rapidly. A single board has already failed. Without intervention, the dam could empty twelve feet of water into Cold Spring Harbor, devastating a thriving ecosystem and permanently altering the landscape.
Our three-phase response
Restoration Plan
The failing edge surrounding the pond has been rebuilt through a $250,000 effort funded by St. John's Church — the first critical step in halting further deterioration.
Engineering studies and immediate repair of the wooden spillway weir — the failing mechanism that could drain the entire pond if left unaddressed.
Complete dam replacement, comprehensive water quality remediation, stormwater management, and full rehabilitation of surrounding wetlands and habitat.
Science & Stewardship
SJPWA works with GEI Consultants — limnologists and ecologists — and Verdantas, the civil engineers leading dam and weir repair. Every decision is grounded in data, from field surveys and water quality analysis to structural engineering assessment.
"The pond is not simply a scenic amenity. It is a functioning freshwater ecosystem that sustains diverse plant and animal communities — and it can be restored."

Governance
SJPWA is an independent New York not-for-profit corporation with 501(c)(3) status, governed by a dedicated founding board drawn from the Cold Spring Harbor community.
