DNR and its partners are moving forward with the removal of the Bloede Dam. Work is expected to begin October 2016. The work will occur in three phases. The first phase is the relocation of the 42" main sewer line which runs through the dam. This will result in the closure of a portion of the Grist Mill Trail for approximately 18-20 months. The initial phase will also require the removal of approximately 7 acres of trees in the vicinity of the dam and the Grist Mill Trail. A Forest Conservation Plan has been developed to ensure successful reforestation (more details to come). During all phases of the project, visitors can expect to see and hear increased truck and construction activity between Illchester Bridge and Bloede Dam.
Work to remove the Bloede Dam structure and retrench a 12” sanitary line that crossing the Patapsco upstream of the dam is expected to start in late fall of 2017 (phase two). This phase is anticipated to take approximately 3 months - with all work being completed by December 2017. The final phase of the project entails final reforestation efforts, as well as installation of two scenic overlooks and interpretive signage. Please stay tuned to this website for details on construction work and trail closures. See the links below and to the left for additional details.

DNR and it's partners have completed the following tasks for developing the design plans:
Looking ahead, DNR and it's partners will work on the following tasks:
Problem: The Bloede Dam is located within the Patapsco River State Park and was built in 1907. The dam is a public safety concern (deaths have occurred), an obstacle for fish passage, and it fragments river continuity and aquatic habitats.
Responsibility: Bloede dam is owned by the Maryland Department of Natural Resources (DNR).
Process: A feasibility study was commissioned to evaluate the dam's negative impact on the ecology of the Patapsco River and issues of public safety. After a thorough analysis and public input (2011-2012), the Department and project partners made the decision to move forward with the Bloede Dam removal with passive sediment management.
With the removal of all or most of Bloede Dam, the department envisions a restored Patapsco River System with a wide range of benefits and long-term cost savings. It is recognized that this decision is not without potential adverse impacts.
A significant historical structure in Patapsco Valley State Park will be lost, there will be short-term impacts to the ecology of the river, fishing and other recreational opportunities will be affected, and there will be temporary inconvenience to park visitors.
However, there will be long-term ecological benefits to the Patapsco River and the Chesapeake Bay, including:
To address the loss of a cultural and historic resource, a portion of the dam structure will be retained on the Howard County side with the placement of appropriate interpretive displays on location and possibly another interpretative display on the Baltimore County side.
