What the flag's design elements mean to its creators:
The two points refer to Mere Point and Princes Point. The three "bays" refer to Maquoit Bay, Middle Bay, and Thomas Bay. The dark blue region refers to the Atlantic ocean. The light blue zigzag refers to the Androscoggin river. The white curves refer to both ocean waves and river rapids (Pejepscot means "the long rocky rapids part of the river"). The green region refers to Brunswick's forest, and if turned upside-down and vertically, can be imagined as two pine trees. When flown horizontally, the green shape resembles the mouth of a salmon, which were once plentiful in the Androscoggin river.

Elements of the flag also represent important ways that the Brunswick area has brought people together. The rapids or waves remind us of the fishing and transportation that our waterways have provided for thousands of years. The lightning bolt-shaped "river" reminds us of the power generation - first for mills and later for electricity - that brought people to live and work by the Androscoggin.
