About this file

This is a Nontidal Wetlands and Waterways Pre-Application Summary document prepared by the Maryland Department of the Environment (MDE) in coordination with Charles County Department of Public Works and Charles County Department of Recreation, Parks & Tourism regarding a proposed dredging project at Wheatley Dam. The pre-application meeting was conducted on August 14, 2025, at 10:00 a.m., with attendees including Sara Albrecht and Sebastian Fernandez from MDE, Keith Roumfort from Charles County Department of Public Works, and Anthony Hancock from Charles County Department of Recreation, Parks & Tourism. The project involves proposed dredging of Wheatley Dam while the lake is drained for separate retrofit construction and repair work being reviewed through MDE Dam Safety. The site is located at Wheatley Lake within Gilbert Run Park, 13140 Charles Street, Charlotte Hall, Maryland 20622. During the site visit, four areas of nontidal wetlands were identified within the lake, with the majority of Wheatley Lake consisting of open water that is not regulated as nontidal wetlands or waterways. The pre-application review determined that proposed dredging may be able to avoid the identified wetland areas entirely, contingent upon finalized dredging plans.

The document indicates that the project would require state authorization, though the specific type depends on final dredging plans and design. MDE staff recommended that once dredging plans are developed, the applicant should consult further with MDE to determine whether authorization would be required and what category of permitting may apply. The 100-year nontidal FEMA floodplain expands beyond the water's edge, and any staging activities within the floodplain would require temporary impact authorization provided the area is restored to prior conditions following work completion. Coves 1, 2, and 4 had clearly apparent wetland boundaries where vegetation transitioned to open water, while Cove 3 contained a more complex braided wetland and stream system where Wheatley Run and tributaries enter the lake. MDE staff emphasized that dredging should be avoided in shallower areas with wetland presence, with further consultation required if dredging must occur near wetland areas. The review was conducted by Sara Albrecht, MDE Nontidal Wetlands Division, who can be contacted at sara.albrecht@maryland.gov or 410-537-3691.

During the site visit, four areas of the lake had nontidal wetlands present (see attachment). The proposed dredging may be able to avoid these areas entirely. Plans for the dredging must be developed and finalized before a determination of potential impacts to regulated resources can be made.

Text37: Coves 1, 2 and 4 (from attachment) had fairly apparent wetland boundaries where wetland vegetation ended as it became open water.

Cove 3 had a more developed braided wetland/stream system where Wheatley Run and other tributaries entered the northern side of the lake. This wetland was still demarcated by the end of wetland vegetation before becoming open water.

Note that the 100-year nontidal FEMA floodplain expands past the edges of the water (see attachment). If staging is proposed within the floodplain, this would require authorization as a temporary impact, as long as the area was returned to prior conditions following the work.

It was discussed that dredging should be avoided within any of the shallower areas where wetlands are present. If dredging must occur near these areas, please discuss further with MDE once plans are designed to determine what kind of authorization may be required.
