Big Otter Lake Trail Rehabilitation 2016: Bridge 4 Current Conditions The Big Otter Lake Trail located within the Ha-De-Ron-Dah Wilderness is a hiking and horseback riding trail in the non-winter months and a cross country skiing trail during the winter. This former road leads from a trailhead in Thendara to the vicinity of its namesake, Big Otter Lake. When this area was designated as Wilderness, the road was closed, gated and maintained as a trail. However, no further measures were taken to put the road to bed. Numerous culverts remained along its entire length, many of which are too small to handle large storm events and some of which have washed out. Following a few heavy rain events in 2015, the eastern end of this trail has deteriorated with numerous washouts. Note that this work plan has been revised (08/2016) to reflect a shorter bridge length (30ft. rather than 40ft.) as well removing the installation of waterbars on the steeper slopes of Moose River Mountain. The means by which materials are to be staged (via helicopter under CP-17 instead of horses) has also been revised. Proposed Actions This project is the last (fourth) in a series all aimed at repairing the damage on this trail. It is expected to begin in the summer of 2017 by a combined effort from the Adirondack Mountain Club s Professional Trail Crew and a volunteer group such as Lean2Rescue. However, materials will be staged via a helicopter during the winter of 2016-2017 under CP-17. At approximately 2.6 miles west on the Big Otter Trail from the wilderness gate (or around 1.5 miles west from the intersection with the East Pond-Lost Creek Trail), another culvert, approximately 24 in diameter, has washed out. Since culverts are nonconforming structures in Wilderness areas, this culvert will be dug up, removed and disposed of off-site. Both banks will be graded back slightly by hand (shovel) and their bottoms will be lined with rock (from the surrounding area) for stability and protection from erosion. In place of the culvert, a bridge will be constructed to span the stream. This bridge will be based on the standard Forest Preserve Snowmobile Bridge Design and have dimensions of 6 feet wide by 30 feet long with 8 ramps leading up to it on each side. This length is necessary to place both ends of the bridge on firmer ground rather than an unstable section of fill the old road was constructed on. The bridge design is attached and provides additional information on this structure.
In order to facilitate a helicopter lift, a helicopter drop zone will have to be installed adjacent to (east of) the bridge site. The boundaries of the drop zone (roughly a 40 ft. by 40ft. square) are flagged with pink flagging. A tally of the trees 3 D.B.H. that will have to be cut is included below (16 in total, approval under L&F Policy 91-2 is being sought). All trees within the drop zone boundary will be felled, bucked up and to the extent practical removed from the drop zone. Approval for the helicopter flight is also being sought under CP-17.

The washed out culvert also presents a safety hazard to those attempting to pass through. Rerouting the Trail: Given the topography in the immediate area, it appears that the present location of the trail (an old road) is routed through the most appropriate location. A reroute would place this trail on steeper slopes that are not hardened, making heavy impact from horseback riders and hikers likely. Repairing the existing trail appears to be the best option. Replacing the Culvert: Culverts are not a conforming structure within Wilderness areas, therefore, this option cannot be pursued.
Staging Materials via Horses: A similar effort in the nearby Pigeon Lake Wilderness revealed limitations in this approach, specifically the physical endurance of horses to haul materials long-distances and the subsequent withdrawal of the volunteer in question. A canvass of the surrounding area uncovered a lack of other teamsters for volunteer work/hire as well, leaving a helicopter drop of materials the only practical option.

Lumber and poles will be dropped off in close proximity to their respective sites using a helicopter sling load. 1 Conceptual Use Plan for Annual Administrative Access by Aircraft into Wilderness, Primitive and Canoe Areas Appendix E Rev. 03.21.12
Alternatives to Motor Vehicle/Aircraft Use -Transport building materials 1.0 miles, 1.8 miles and 2.6 miles in by horses/hand to the project sites within the Ha-De-Ron-Dah Wilderness. -Use native materials. Impacts to Program if Aircraft Access in Wilderness is Eliminated -Horse teams have locally proven difficult to enlist/hire for these projects so materials probably would have to be staged by hand carry. -Greater staff time necessary to transport heavy materials long distances by hand over challenging terrain. -Increased frequency of maintenance associated with the shorter lifespan of native materials. Proposals to Reduce Use of Aircraft in Wilderness (Explain how this meets your Division s Wilderness Flights Reduction Plan) The use of treated materials will increase the lifespan of the bridges subsequently reducing the need for future aircraft operations into these areas. This flight serves multiple projects within this wilderness area and will be combined with other projects to the extent practical. Motor Vehicle/Aircraft Type UMP Authorized Project?
