Now more than ever, Lake Winnipesaukee needs our help.

The spread of cyanobacteria and other pollutants has placed our lake on the EPA’s list of threatened or impaired water. The Lake Winnipesaukee Association has been awarded a generous grant of $650,000, contingent on the community raising $163,000 in further support. This means every dollar you donate will go five times as far.
