Appendix_G_Wheatley_Reservoir_Bathy_Contours_Depths.pdf

This appendix document supports a dredging services procurement issued by Charles County, Maryland for work at Wheatley Dam reservoir located in Gilbert Run Park. The project requires wet dredging, hauling, and sediment disposal or beneficial reuse services within defined areas of the reservoir, with initial focus on northern and eastern zones where bathymetric and sub-bottom profiling surveys conducted in late 2024 identified significant sediment accumulation. The volume of sediment to be dredged is contingent upon contractor pricing per cubic yard and associated project costs. Charles County reserves the right to request post-dredging bathymetric survey data documenting elevation changes following the dredging event. Given the reservoir's location within a public park, dredging activities must be coordinated with park accessibility and operational schedules. Contractors are encouraged to conduct site visits during normal business hours prior to bid submission. The site is accessible at Gilbert Run Park, 13140 Charles Street, Charlotte Hall, Maryland 20622.

This appendix specifically contains bathymetric contours and depth information for Wheatley Reservoir, which serves as technical supporting documentation for bidders to evaluate project scope and sediment removal requirements. No specific contract value, budget parameters, or funding source details are disclosed within this appendix. The document functions as a reference tool enabling qualified dredging contractors to assess site conditions, determine appropriate equipment and methodologies, and develop informed cost proposals based on actual reservoir bathymetry and sediment depths in the targeted dredging areas.
