2021 Map of Simsquish Lake

About this map

The St. Croix River forms the international boundary with Canada at the eastern edge of this Washington County landscape, where the Maine wilderness is defined by an intricate network of waterways. Centered on the sprawling wetlands of Tomah Stream, the area contains several isolated water bodies including Simsquish Lake and Hound Brook Lake. The terrain is characterized by modest elevations like Pattingill Ridge and the broad depressions of Haycock Bog. A sparse road network, including Vanceboro Rd and Tomah Dam Rd, provides the only overland access through this heavily forested timberland. The presence of numerous brooks—from Beaver Brook in the north to W Br Millberry Brook in the south—indicates a landscape historically utilized for its water resources and natural drainage before reaching the river system.
