Assabet River NWR

Welcome to the Assabet River National Wildlife Refuge!

The refuge, part of the National Wildlife Refuge System, encompasses 3.5 square miles located within the towns of Hudson , Maynard, Stow and Sudbury. Formerly part of Fort Devens, this area was known as the Sudbury Training Annex. The U.S. Army transferred 2,230 acres to the U.S. Fish and Wildlife Service in the fall of 2000. Our primary purpose is to manage these lands for migratory bird conservation.

Assabet River is one of eight refuges within the Eastern Massachusetts NWR Complex, which is headquartered out of Great Meadows NWR and located at 73 Weir Hill Road, Sudbury, Massachusetts, 01776. For more information about Assabet River NWR, visit the Weir Hill office weekdays from 8:00 am to 4:00 pm, contact the Refuge Manager at (978) 443-4661 or visit the Friends of Assabet River NWR at www.farnwr.org.

Recreational Opportunities

At the Assabet River NWR, the public is invited to engage in appropriate, compatible wildlife-dependent public use. The terms “appropriate” and “compatible” come from the National Wildlife Refuge System Improvement Act of 1997, which established the mission for the refuge system and developed overall guidance for management of the system.

The Refuge is open from one half-hour before sunrise to one half-hour after sunset. Wildlife-dependent recreation opportunities, including wildlife observation, photography, interpretation, and environmental education, are permitted on designated trails. The refuge first opened for wildlife-dependent recreational use in March 2005. A phased opening of trails was announced in the 2005 Comprehensive Conservation Plan for the refuge. Based on feedback from visitors, volunteers and our Friends group, and due in large part to our decision to construct the Complex’s visitor center at Assabet River NWR, we have reworked the trail system. By Memorial Day 2007, we plan to open slightly more than 4 miles of new trails to the public. At the same time, 2.5 miles of roads and trails will be closed. A total of 16 miles of trails and roads will be open for wildlife-dependent public use at the refuge.

If you have visited the refuge before and walked the trails, the following areas are being closed: Trail B and the Patrol Road from White Pond Road to the north gate in Stow . The new trails that are being opened are Trail E, Trail G, Trail H, Trail U, Trail V, Trail W, Trail X, Trail Y and Trail Z. We have also renumbered the trail intersections. The new trail configuration is shown on the attached Printable Trail Map Please remember that you must stay on marked trails in order to decrease disturbance to refuge wildlife.

We are not currently charging a fee for use of the refuge trails or parking area. We will institute a fee program in the future.

Fishing and hunting are allowed subject to refuge regulations, State and Federal laws and permit restrictions. The most intense hunt period is during the shotgun deer season. Most other times, hunt pressure is generally light. Please refer to information in the kiosks or on the refuge website for more information about hunt seasons. Fishing is allowed at Puffer Pond on Trail Z at the Barron Fishing Access Site. Kayak and canoe access will be allowed off Craven Lane beginning in the summer of 2007 (carry in only at this time).

Refuge lands are closed to horses, bicycles, and motorized vehicles. Dogs are not allowed. There are no picnic areas or campsites on the refuge. Construction of a 5,000-square foot visitor center, to be located just northeast of trail intersection 13, should begin by fall 2007. When the visitor center is opened to the public, bicycling on certain refuge roads will be allowed.

At this time, parking is available off Hudson Road in Sudbury and White Pond Road in Stow .

Please be aware that vehicles operated by U.S. Fish and Wildlife Service and U.S. Air Force staff, volunteers and contractors, may be operating on refuge roads and trails.

We are a pack it in, pack it out refuge. Please help us keep the refuge clean by bringing home your trash.

To help you plan this and future visits to the refuge, please consider the following trail lengths:

The large wetland complex and the contiguous forested areas found here today are important feeding and breeding areas for migratory birds. We ask that you help conserve this unique natural habitat and minimize disturbance to wildlife by staying on designated trails

Have a safe and enjoyable visit to the refuge!
