Sediment Temporarily Impacts Fishing Below Bloede Dam

Ellicott City, Md. (March 30, 2012) - Since the removal of Simkins Dam, sediment has made its way down the Patapsco River and is now filling deeper holes and pools below Bloede Dam. The Department of Natural Resources (DNR) reminds recreational anglers that this is only temporary. The occurrence is an expected and natural process that was accounted for during initial planning.

WARNING: Paddlers & Anglers

Recent storms have scoured out areas of the Patapsco River at the old Union Dam site leaving exposed concrete and rebar, creating hazardous conditions. Park staff has clearly marked the hazards and will work to remove them as soon as possible. The Patapsco River and river bank remain closed through this construction area until further notice.
