Appendix_F_Wheatley_Reservoir_Bathy_Depths.pdf

Appendix F is a bathymetric data file prepared for Charles County, Maryland's Wheatley Dam Dredging Services project. The document supports a sealed bid solicitation from qualified dredging firms to provide wet dredging, hauling, and sediment disposal or beneficial reuse services within specified areas of the Wheatley Reservoir. Bathymetric and sub-bottom profiling surveys conducted in late 2024 identified significant sediment accumulation in the northern and eastern areas of the reservoir, which will serve as the focus for an initial dredging event. The project is located at Gilbert Run Park in Charlotte Hall, Maryland. Contractors are encouraged to review all project documents and conduct site visits during normal business hours prior to submitting bids. The specific quantities of sediment to be dredged will be determined based on the contractor's cost per cubic yard and other associated project tasks. Charles County may request post-dredging bathymetric survey data to document changes in elevation following the dredging event.

Dredging activities must be coordinated with park accessibility and ongoing activities due to the reservoir's location within a public park. The appendix provides critical bathymetric depth information necessary for contractors to develop accurate cost estimates and project schedules. No specific contract award date, contract term, funding amounts, or pricing terms are detailed in this file, as it functions as a technical reference document supporting the broader procurement solicitation.
