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 501(c)(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.
As always, the threats from invasive species are growing, especially with this year's mild winter, early spring and warmer summer.
Under Maine law, it is now illegal to transport ANY aquatic plant on the outside of a vehicle. It is also illegal to sell, propagate, or introduce to Maine waters these eleven invasive aquatic plants.
Generally found in flowing water or proximity to flowing water (e.g., river mouths). Feed primarily on particulate detritus in soft sediments.

FYI - Coast Guard recall alert on SeaDoo Switch (a pontoon boat from SeaDoo) for potential capsizing issue. Most folks have their boats out of the water at this point, but FYI in case you have one of these: https://www.uscgboating.org/library/articles/US_Coast_Guard_Safety_Alert_18-25_Sea-Doo_Switch_Capsizing_Hazard.pdf
