Watersheds of the Chesapeake Bay
Bohemia Creek | Broad Creek | C&D Canal West | Chester River | Choptank River | Deep Creek | Elk River | Gravelly Branch | Gum Branch | Marshyhope Creek | Nanticoke River | Perch Creek | Pocomoke River | Sassafras River | Wicomico River
Depression (D-), flat (C-), and riverine (D+) wetland types were assessed and graded (grade in parenthesis) in this watershed. The most common stressors to these wetlands were forestry, invasive plant species, filling, ditching, garbage, and stream channelization in the wetland, and roads in the lands surrounding the wetland (buffer). The complete reports and data for this assessment are available online.
EPA established a Total Maximum Daily Load for nitrogen, phosphorus, and sediment for the entire Chesapeake Bay Watershed. This TMDL requires reductions of approximately 24% for nitrogen and 20% for phosphorus between 2009 and 2025 from all of the Chesapeake watersheds within Delaware. Sediment loads from Delaware's portion of the Chesapeake must remain at 2009 levels under this TMDL.
Each of the sites is sampled through the program listed above for a consistent suite of environmental contaminants. These contaminants are broadly classified as Volatile Organic Compounds (VOCs), Semi-Volatile Organic Compounds (SVOCs), Pesticides, Polychlorinated Biphenyls (PCBs) and Metals as listed using USEPA and DNREC defined standards. When sites are adjacent to water bodies sediment samples are collected to assess potential impact from a site on the health of the waters.
If you would like to view reports for any of the sites in the SIRS program please follow the link the DNREC Environmental Navigator to search by map for the Nanticoke River Watershed.
Captain John Smith set off on the Chesapeake Bay around 6 June 1608, determined to discover the mythical treasures of the Far East. While on his adventure, he came upon the river we now call the Nanticoke. He became acquainted with the Native Americans residing near the River, calling them the Nantaquak. Unable to successfully farm on the marshy ground, they thrived predominately on hunting and fishing. The Nanticoke were accomplished canoeists, and their close ties to the River inspired their name, which means "those who ply the tidal stream," "sea shore settlers," or "tidewater people."
Evidence of Native American habitation can be found along the river systems in the Nanticoke watershed. The Nanticoke tribe established a network of villages and encampments, which persisted until the area was taken over by European settlers. Artifacts include piles of discarded oyster shell called shell middens. There are additional deposits that contain stone tools and property. Over 300 archeological sites have been documented in the Nanticoke River.
