  • Millions of years ago, sharks, whales, crocodiles and other creatures inhabited the waters and shores of this area. Most of these animals are now extinct, others are just no longer found here.
  • To the sharp-eyed visitor, shark teeth and other Miocene fossils may be found along the park's shoreline.

Flag Ponds Nature Park is also part of Maryland's history.

  • From the early 1900's until 1955, three shanties housed fishermen during the main fishing season who worked a major "pound net" fishery supplying croaker, trout and herring to markets as far away as Baltimore.
  • Known as "Buoy Hotel", the last shanty was destroyed in 2012 in a fire. It was rebuilt in 2015.

Flag Ponds Nature Park Shoreline

The Board of County Commissioners entered into a project agreement with the State of Maryland Department of Natural Resources (MD DNR) for a no-interest loan to design and construct a living shoreline at Flag Ponds Nature Park. The design is complete, and all permits have been received, with the bid documents for construction pending. This project only covers the first 500 feet of problematic shoreline. Future phases of shoreline protection would extend approximately 6,000 feet south of the proposed project, ultimately protecting the entire shoreline of Flag Ponds Nature Park. Shoreline erosion threatens the two freshwater ponds separated from the Chesapeake Bay by a narrow beach dune system. A breach and intrusion of brackish water would essentially destroy the freshwater aquatic and wetland ecosystems. Duncan’s Pond (approx. 9 acres) is the southern, most vulnerable pond; Richardson’s Pond (approx. 28 acres) has a well-traveled boardwalk where visitors observe the unique freshwater pond ecology, while environmental education programs provide meaningful watershed experiences and field studies.
