Square Pond is located on the border between Shapleigh and Acton, in southern Maine. The lake is spring fed and has few other natural inlets or outlets.

Today, most of the lakefront property is owned by summer residents from out of state. Over 400 camps and residences dot the shoreline. Many are now owned by second and third generation families. Each year, a few more “camps” are converted for year round residences.

The Square Pond Improvement Association (SPIA), an IRS 501C-3 organization, was formed by Square Pond lake shore property owners in approximately 1958. SPIA is dedicated to protecting the lake environment, especially water quality, shoreline and area wildlife. The SPIA is also active in promoting group recreation and water safety awareness.
