Bathymetric Survey Document

This is a bathymetric contours and depths map for Wheatley Reservoir, prepared for Charles County, Maryland in support of a dredging services contract opportunity. The document presents survey data collected in late 2024 that identified significant sediment accumulation requiring removal through dredging operations. The map illustrates depth contours and sediment distribution across the reservoir, with particular focus on the northern and western cove areas designated as priority zones for the initial dredging event. The survey data forms the technical foundation for bidders to assess project scope, sediment volumes, and dredging requirements when submitting sealed bids for wet dredging, hauling, and sediment disposal services. The project location is Gilbert Run Park at 13140 Charles Street, Charlotte Hall, Maryland 20622, and contractors are encouraged to review all survey documents and conduct site visits during normal business hours prior to bid submission.

The bathymetric information provided in this survey document enables qualified dredging contractors to accurately estimate costs per cubic yard and develop comprehensive project proposals that account for sediment volumes, disposal logistics, and scheduling constraints imposed by the public park environment. Project execution must be coordinated to minimize disruption to park accessibility and recreational activities, requiring contractors to demonstrate operational flexibility and site management capabilities in their bid proposals.
