2018 Map of Pemadumcook Lake

About this map

Pemadumcook Lake dominates this central Maine landscape, serving as a massive hydraulic hub connecting the West Branch Penobscot River and a complex of smaller basins including Jo-Mary Lake and Ambejejus Lake. This 2018 survey reveals a terrain defined by its water-and-woods character, where the Appalachian National Scenic Trail winds through the southwestern corner near Potaywadjo Ridge and Cooper Brook. The map illustrates a region managed for both conservation and timber access, with named paths like the Tirio Access Rd cutting through the dense forest between Lincoln Ridge and the shores of Middle Jo-Mary Lake. Local landmarks such as White Horse Island and Sweet Potato Island dot the expanse of the larger lakes, while the Piscataquis and Penobscot county line bisects the southern waters near Turkey Tail Lake.
