Nesowadnehunk Stream is a tributary of the west branch of the Penobscot River with its source located at the outlet of Nesowadnehunk Lake. This 17-mile stream flows roughly along the western and southern boundary of Baxter State Park (BSP) in northern Maine (see The Maine Atlas and Gazetteer map 50; the outlet of Nesowadnehunk lake is on map 50 B4). About three quarters of the stream runs approximately parallel to the Park Tote Road which connects the south entrance (i.e., Togue Pond Gate) to the north entrance (i.e., Matagamon Gate) of BSP. The surrounding watershed is hilly and deeply forested with a mixture of evergreen and deciduous trees. The stream is typically 20 to 40 ft wide and has a depth ranging from < 1 ft to > 4 ft. Depending on the location, the substrate varies from soft silty mud, to coarse gravel, to exposed bedrock, to boulders. Fishing on this stream is particularly enjoyable in late summer-early fall due to the cooling surface water and the total lack of black flies, mosquitos and deer flies which can drive even the most dedicated angler to insanity in the spring and early summer. Keep in mind that open-water fishing in this part of Maine ends on September 30, whereas BSP closes for the season on October 15.
