About Us
At the turn of the century, Squam was quite different from the scene we enjoy today. The surrounding mountains were cleared by logging, sawdust several feet thick had settled in many of the coves, driftwood made navigation hazardous, and refuse, including tires, mattresses and dead animals, had been dumped in the lakes.
In 1904, the Squam Lakes Improvement Association was formed by a group of concerned landowners. In 1905, the association was legally incorporated as a non-profit conservation organization and renamed Squam Lakes Association (SLA). Initial efforts of the SLA were focused on eliminating pollution from the lakes, maintenance of the water level, boat safety and navigation. Through cooperative relationships with local and state governments and the dedication of four generations of people who loved Squam, the watershed has been uniquely conserved.
