WSSC Extends Winter Trail Pilot Program at Triadelphia Reservoir for 2015-16 Season

Equestrian enthusiasts and hikers
will continue to enjoy the trail year-round

Laurel – November 3, 2015 – WSSC is extending its Winter Trail Pilot Program allowing the Triadelphia Access Road along the Triadelphia Reservoir to remain open for multipurpose use during the 2015-2016 winter months. Effective December 1, horseback riders, birdwatchers and hikers will be able to enjoy use of the Access Road through the winter as well as spring, summer and fall seasons.

The Pilot Program opens the 4.5 mile Triadelphia Access Road that traces the southern boundary of the reservoir in Montgomery County as a year-round multi-use trail. The blue stone parking lot, located on Triadelphia Lake Road, will be the only entrance to the Access Road during the winter. This lot provides ample parking space for six to eight horse trailers. Once the reservoir reopens to all visitors on March 15, 2016, the upper parking lot at Green Bridge Recreational Area will open to horse trailers as well, providing entrance to the Access Road from both ends. There will be no other trail entrances between the Triadelphia Lake Road and Green Bridge Recreational Areas.

The Pilot Program applies to land activities on the Access Road only. All other areas of the reservoir will close for the season on November 30. All fishing or boating activities will resume on March 15, 2016 (weather permitting) for the 2016 season.

WSSC will enforce its same watershed use regulations on the Access Road.

  • Anyone 16 years or older must possess a valid WSSC Watershed Use Permit.
  • Minors under the age of 16 must be accompanied by someone 18 years of age and hold a valid WSSC Watershed Use Permit.
  • All horseback riders must wear a helmet.
  • No animal waste can be left on parking lots or roadways.
  • Season and day permits are valid for use of the Access Road.
    • 2015 season permits are valid thru December 31, 2015
    • 2016 season permits are required starting January 2, 2016
  • Season and day permits can be purchased online or in person at:
    • www.wsscwater.com
    • Richard G. Hocevar Building Cashier’s Window
    • Brighton Dam Visitor’s Information Cabin
  • 2016 season permits can be purchased beginning January 2, 2016.

Horseback riding, bird watching and hiking are allowed on the Access Road only. The creation or use of side trails will not be permitted. Riders, birdwatchers and hikers will need to strictly adhere to the “Stay on Trail” signs visibly posted along the Access Road.

The trail will be closed to horseback riding in wet weather and when the trail is wet and muddy to protect the watershed from erosion. You can find out the daily status of trails by checking WSSC’s website at http://www.wsscwater.com, our watershed recreation Facebook page at https://www.facebook.com/WSSCWatershedRecreation or by calling the “4Fun” hotline at 301-206-4386. Access Road trail maps and complete rules and regulations are available online under the Education and Recreation section of our site.

The Access Road will be open daily from sunrise to sunset. On days when managed hunts occur on Triadelphia Reservoir, the entire reservoir including the Access Road will be closed until 1 p.m.

Hunts are currently scheduled for:

  • December 1, 3, 21, 28, 30, 2015
  • January 12, 2016

The pilot program is consistent with recommendations in a 2012 study performed by EA Engineers on behalf of WSSC and several months of working with the local community and equestrian enthusiasts. The study determined that Triadelphia Access Road only has a small amount of highly erodible soil (HES) allowing WSSC to provide public access to the road. The program will be re-evaluated based on erosion and environmental impact on the Access Road and the reservoir prior to the 2016-2017 winter season.
