The final report for the Deep Creek Lake Arrowhead Cove Pilot Dredging Project has been completed and is now available online at https://bit.ly/3ZBt5XS.
The sediment management and dredging initiatives at Deep Creek Lake illustrate a comprehensive approach to addressing environmental challenges while balancing recreational needs and economic considerations. Arrowhead Cove’s selection for dredging represents a strategic decision based on extensive evaluation and community priorities, setting a precedent for future actions to preserve Maryland’s largest freshwater lake.
Spanning 23.5 acres of surface water, the cove faced challenges with sediment accumulation. In response, the state of Maryland through the Department of Natural Resources allocated $2.2 million for a pilot Deep Creek Lake Arrowhead Cove Dredging Project, encompassing final design, permitting, procurement, and construction.
Spearheaded by Garrett County Government in collaboration with Maryland Environmental Services, and supported by Anchor as the design engineer, the project sought to remove accumulated sediment in Deep Creek Lake’s Arrowhead Cove through mechanical removal. Through a competitive sealed bid process, Byco Enterprises, Inc. was awarded the contract for the task.
Mechanical dredging in the dry during late fall and early winter was demonstrated to be an effective tool for removing a relatively large amount of accumulated cove sediment. Commencing in November 2023, the dredging operation successfully removed approximately 11,000 cubic yards (734 dump truck loads) of sediment. The sediment removal was completed in January 2024.
There were quite a few restrictions placed on the dredging project through permitting, timing, weather, and pressure to not impact recreational use. Many of these restrictions led to an increase in project costs, and with a fixed project budget, this results in less sediment being removed within the allotted budget.
The project has successfully improved boating and swimming access in the cove. Yet, impacts on fishing and submerged aquatic vegetation (SAV) require ongoing monitoring. The re-establishment of SAV is expected to enhance water quality and restore habitat over time.
The Arrowhead Cove Dredging Project represents a critical step in preserving and enhancing the natural beauty and usability of Deep Creek Lake. The lessons learned from this initiative will be invaluable as efforts continue to protect this vital resource for both residents and visitors.
