Located in eastern North Carolina in Hyde County, the Mattamuskeet National Wildlife Refuge consists of more than 50,000 acres of water, marsh, timber and crop lands. The refuge's most significant feature is Lake Mattamuskeet, the largest natural lake in North Carolina. The lake is 16 miles long, five to six miles wide, encompassing approximately 40,000 acres, but averages two feet in depth. Mattamuskeet NWR lies in the middle of the Atlantic Flyway and provides valuable migration and wintering habitat for waterfowl and other migratory birds. Waterfowl numbers exceed 100,000 each winter and include snow geese (5,000-8,000), Canada geese (5,000-10,000), tundra swans (25,000-35,000) and 22 species of ducks (90,000-150,000). While noted for its waterfowl, Mattamuskeet NWR also provides habitats for a significant fishery resource, 70-90 pairs of nesting osprey, wintering bald eagles and peregrine falcons, deer, bobcats, otters, gray foxes, an occasional black bear or red wolf, 240 species of birds and numerous other species endemic to the area.
