Continued . . .


Today, primarily because of the stewardship of a few large landowners, the land around Umbagog Lake has remained largely undeveloped, preserving the largest freshwater marsh complex remaining in New Hampshire. The area provides excellent wildlife habitat for migratory birds, endangered and threatened species, resident wildlife, and rare plant species.

Umbagog Lake itself--more than 10 miles in length and covering more than 8,500 acres--is one of the largest lakes along the New Hampshire/Maine border. It has an average depth of only 15 feet. More than 50 miles of shoreline, many islands, and extensive wetlands and marshes along the rivers all provide ideal habitat for waterfowl pairing, nesting and brood rearing during the summer.

The forested swamplands and upland areas are important habitat for many species of passerines, including 24 varieties of warblers.


Umbagog Lake hosts the largest nesting concentration of common loons in New Hampshire. Abundant fish populations and wetland habitat support one of the highest concentrations of nesting osprey in New Hampshire. The area's forested wetlands support good numbers of black ducks, ring-necked ducks, and goldeneye. Wood ducks, hooded and common mergansers and mallards also nest in the area. The lake provides habitat for migrating scaup, three varieties of scoters and Canada geese.

The area also provides habitat for protected species like the bald eagle and other raptors. In 1989, bald eagles successfully nested at Umbagog Lake for the first time in New Hampshire since 1949.

Migratory non-game birds like the northern harrier, American bittern and great blue heron depend on the area around Umbagog Lake. Also found around the lake are gray jay, spruce grouse, black-backed and northern three-toed woodpeckers and palm warblers, all northern species considered rare in New Hampshire.
