Formerly Lake Winnipesaukee Association, we’re building an alliance to protect our lake.
Let’s Keep Moments Like These From Being Just a Memory
The spread of cyanobacteria and other pollutants risks placing our lake on the EPA’s list of threatened or impaired waters. The Lake Winnipesaukee Alliance has been awarded a generous EPA grant of $500,000 to support our lake protection efforts. Thank you to everyone who contributed to the matching challenge that helped make this possible. Continued support is vital—every dollar you give goes directly back into protecting the lake we all love.
