Dam Boards Installed | Water Levels near Normal for Summer
The boards are in on the Silver Lake dam, and May water levels are near their normal summer range. The dam has some leaks and aging cracks, but it is not in any immediate danger. A new Dam Committee has been formed to evaluate long-term solutions, and a new Selectman has applied for a federal grant to help fund the eventual dam replacement. In the meantime, steady as she goes

September 12, 2025 Surface Layer Survey
On September 12, Cliff Cabral of New England Milfoil spent 9.5 hours performing a surface survey of Silver Lake. The visibility was perfect; low wind, flat water, and a sunny day! See the news post for results!
Our Mission
The mission of the Silver Lake Association of Madison is to:
- Promote and protect the general welfare of Silver Lake and its environment
- Monitor the quality of the water in Silver Lake
- Conduct programs to support an active and informed membership
- Encourage the support of the Town of Madison in accomplishing these objectives.
What we do
Aquatic Invasive Species (AIS) Prevention
Our Aquatic Invasive Species (AIS) Prevention program includes the Lake Host Program to inspect and power wash boats and trailers before they enter the Lake, and the Weed Watchers to monitor for invasive species.
Water Quality Monitoring
This program was designed to quickly identify water quality changes and problems through regular measurement and testing.
Advocacy
Aquatic Invasive Species (AIS) Remediation
In the event that we experience an AIS infestation such as milfoil, SLAM has established remediation plans and partnerships and we’ve started a fund to help pay the costs.
Watershed Planning
SLAM is embarking on a multi-year process to develop a Watershed Management Plan (WMP) that will include expert analysis of our Silver Lake watershed and details plans and projects for protecting it for the long term.
Please don’t feed the birds
The geese that visit Silver Lake produce a prodigous amount of feces which pollutes our water and makes it unhealthy to swim in. Further, the geese “adopt” our lake and breed, becoming an increasing problem each season. Ducks and, especially, ducklings are very entertaining creatures. Unfortunately, they carry a parasite which causes a condition called “swimmer’s itch”. Swimmer’s itch causes a very unpleasant itching/burning sensation. Feeding the ducks encourages them to linger on Silver Lake and increases our exposure to the parasite.
It is against the local laws to feed either bird!
Please be aware of the loons
When boating on the lake please be aware of the loon nesting buoy at the head of the lake and give them plenty of space. For more information please visit loon.org
