Wheatley_Reservoir_Bathy_NAVD88_-260817.pdf

This is a bathymetric survey document for Wheatley Dam Reservoir in Charles County, Maryland, prepared in support of a dredging services contract opportunity. The survey was conducted in late 2024 and identified significant sediment accumulation in the northern and western cove areas of the reservoir, which are designated as the focus areas for an initial dredging event. The document provides detailed bathymetric data and sub-bottom profiling information necessary for dredging contractors to assess project scope and prepare accurate bids. Charles County Commissioners are requesting sealed bids from qualified dredging firms to perform wet dredging, hauling, and sediment disposal services within the defined survey areas. The volume of sediment to be dredged will be determined based on contractor pricing per cubic yard and overall project economics. Given the reservoir's location within Gilbert Run Park at 13140 Charles Street, Charlotte Hall, Maryland 20622, dredging activities must be coordinated with park accessibility and public use schedules. Contractors are encouraged to review all project documents and site plans and conduct site visits during normal business hours prior to bid submission.

The survey document serves as a technical foundation for bid development, enabling contractors to analyze sediment distribution, depth profiles, and removal requirements across the identified dredging zones. Pricing will be structured on a cost-per-cubic-yard basis, with the final dredging volume and project cost dependent upon submitted bids and associated mobilization, transportation, and disposal tasks. The project represents an environmental management initiative to maintain reservoir functionality and water quality while balancing operational constraints imposed by the public park setting and seasonal usage patterns.
