2014 Map of Loon Bay

About this map

The international border between Maine and New Brunswick follows the winding course of the St Croix River, defining the geography of this part of Washington County. This remote river corridor is characterized by a series of river rapids and expansions, notably Haycock Rips, Rocky Rips, and Canoose Rips, which denote the fluctuating elevation and flow of the waterway as it moves toward the Atlantic. The landscape is dominated by dense hydrology, including Hound Brook Lake and the significant basin of Loon Bay. Drainage from the interior is carried by Simsquish Brook, Ellen Brook, and Hound Brook, feeding into the larger Grand Falls Flowage. Small landforms like Cedar Island and Grassy Islands sit within the river channel, marking the literal edge of the United States of America.
