2021 Map of Loon Bay

About this map

The St. Croix River forms the international boundary between Maine and Canada, weaving through a series of significant white-water features including Meetinghouse Rips, Rocky Rips, and Split Rock Rips. This stretch of the river in Washington County is defined by its complex hydrology and diverse wetland ecosystems. Low-lying areas like Haycock Bog and water bodies such as Hound Brook Lake feed into the river system via named tributaries like Rolf Rollingtier Brook and Simsquish Brook. Settlement is sparse, with Loon Bay Rd providing the primary overland access to the river's edge at Loon Bay. The map highlights the interplay of islands and landforms along the border, specifically Cedar Island and the prominent bend known as The Cape, where the river current is influenced by Tyler Rips and Cedar Island Rips.
