NOTICE: The Grist Mill Trail in the Avalon area of Patapsco Valley State Park, including the swinging bridge (bridge from Orange Grove to the Grist Mill Trail) is now open from Lost Lake north to the Saw Mill and Forest Glen trails.

Bridges and the paved trail are washed out in areas, resulting in STREAM CROSSINGS. Stream crossings can be slippery and subject to FLASH FLOODING. PLEASE USE CAUTION, and pay attention to all closure and emergency flash flooding exit signs.

The Lost Lake area itself remains closed due to damage caused by flooding events.

The Grist Mill Trail north of the Saw Mill and Forest Glen trails to Ilchester Road remains closed, due to ongoing construction related to the Bloede dam removal project. The Saw Mill and Forest Glen trails are now open to the Grist Mill Trail (hiker only).

The Vineyard Springs Trail and all other trails connecting the Santee Trail to the Grist Mill Trail are now open.

Hilltop Road Trailhead: Buzzards Rock Trail is open to HIKING ONLY to the Ilchester Rock overlook. ALL other trails are closed. There is no access to Grist Mill trail from Hilltop Road.

For details, and current status of the Bloede Dam project, you can visit the DNR Bloede Dam web page or see the park bulletin board.

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
