Lower Otter Creek Wildlife Management Area (WMA) includes acres of wetland and floodplain forest near the mouth of Otter Creek in Ferrisburg, Vermont. Boat access is via the Creek or Lake Champlain. There is a State boat access on Fort Cassin Road. Otter Creek is navigable by motorboat for several miles, as far as the falls in Vergennes. There is walk-in access for the parcel bordering Sand Road. The WMA is owned by the State of Vermont and managed by the Vermont Fish & Wildlife Department. Otter Creek has formed a delta at its mouth that reaches out into Lake Champlain. North of the delta is the protected Porter Bay (also known as Flat Rock Bay). South of the point is a more open bay called Fields or Kellogg’s Bay. There is an oxbow farther upstream called Porter Lake, which is excellent duck breeding habitat. Otter Creek’s delta is covered mostly with silver maple- green ash swamp but the WMA also supports silver maple- sensitive fern riverine floodplain forest. Other tree species found on the WMA are hemlock, American elm, black ash, white, swamp white and red oak. Wetlands occur upstream from the mouth and in the corners of Porter Bay. These wetlands support a deep bullrush marsh component, cattail marsh and buttonbush shrub swamp. The WMA also has a small old-field component. Arrowleaf, narrow blue-eyed grass, marsh vetchling, lance-leaved loosestrife, water hemp, cat-tail sedge, yellow pimpernel, foxtail sedge, yellow water-crowfoot, green dragon and folliculate sedge are rare plants that have been found in the WMA. State-endangered ospreys nest in the WMA, both on manmade platforms and in trees. Bald eagles are often seen here, especially in winter. Two types of mussels, the pink heelsplitter and State-endangered fragile papershell, have been found in Otter Creek. All threatened and endangered wildlife is protected by law and should not be disturbed.
