Patapsco Valley State Park

Bloede Dam Removal Project

Park, Trail and River Closures

Due to the construction associated with the Bloede Dam Removal Project, portions of the Grist Mill Trail, the Patapsco River and the park will be closed to visitation. All closures will occur between Ilchester Road to just downstream of Bloede Dam. For details, and current status of this project, you can visit the DNR Bloede Dam web page or see the park bulletin board.

Bloede Dam


What will I see and how will this project impact my visit?

  • Access to the park will be CLOSED between Ilchester Road to just downstream of Bloede Dam on or about September 5, 2017 until approximately April 2019.
  • Approximately .5 miles of the Grist Mill Trail will be CLOSED between Ilchester Road to just downstream of Bloede Dam on or about September 5, 2017 until approximately April 2019.
  • All access to the river, including but not limited to swimming, fishing, paddling and tubing, will be CLOSED between Ilchester Road to just downstream of Bloede Dam on or about September 5, 2017 until approximately April 2019 during construction. There will be less than a mile of river that will be closed between Ilchester Road and the swinging bridge.
  • The hiking/biking trail leading from Buzzard Rock to the Grist Mill Trail will be OPEN
  • Five acres of forest will be cleared between the Grist Mill Trail and the Patapsco River.
  • Once the dam is removed, the river will experience changes, such as the expansion of sand bars, due to heavy sediment releases for an undetermined amount of time. These changes could impact the quality of fishing below the dam.

The Bloede Dam Removal Project will:

  • Improve public safety
  • Enhance recreational opportunities
  • Provide fish passage to spawning habitats upstream
  • Create a free-flowing river experience for all to enjoy in the park
