Information: Umbagog Lake is a wilderness lake located in Coös County, New Hampshire and Oxford County, Maine. It is one of the most pristine lakes in the state of New Hampshire and lies near Errol, New Hampshire and the Thirteen Mile Woods Scenic Area along the border with Maine. The name Umbagog is properly pronounced with the stress on the second syllable (um-BAY-gog) and is said to come from the Abenaki word for "shallow water". The lake is part of a National Wildlife Refuge and a New Hampshire state park. Along its southernmost shore, there is a public campground and a public boat launch ramp which may be accessed from New Hampshire Route 26. There are 26 wilderness campsites, accessible only by boat, which are located around the lake. An interesting feature along its northwest shore is an expansive natural floating island composed of generations of decomposing marshland vegetation. The area is abundant with wildlife, including moose, rabbit, bear, and many other native species.
