Delaware Watersheds

The Cedar Creek watershed is located in the eastern portion of Sussex County. The Cedar Creek is 15 miles in length. The major watercourse in this watershed is Cedar Creek. Major waterbodies within this watershed are Cubbage Pond, Clendaniel Pond, and Cedar Creek Mill Pond. Cedar Creek flows in a generally northeasterly direction into a stream called Slaughter Neck Ditch which subsequently flows northward and discharges at the mouth of Mispillion River.

The watershed is sparsely populated with no incorporated communities. Major land use in the area consists of agricultural lands and tidal marsh and swamp.

DNREC's Wetland Monitoring and Assessment Program (WMAP) has been developing scientifically robust methods to monitor and evaluate wetlands in Delaware on a watershed basis. Learn more about the health of the wetlands in this watershed from the DNREC Wetlands Monitoring and Assessment Program.

There are nutrient and bacteria TMDLs for the Cedar Creek watershed that require a 45% reduction in nitrogen loads, a 45% reduction in phosphorus loads, and a 95% reduction in bacteria loads.

The designated uses for the Cedar Creek include primary recreation, secondary recreation, fish, aquatic life and wildlife, industrial water supply, and agricultural water supply in freshwater segments. This watershed also is designated as waters of exceptional recreational or ecological significance for the marine waters segments.

This watershed has sites sampled 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. Learn more information specific to this watershed from the DNREC Advanced Facility Search Tool.

Delaware's Department of Natural Resources and Environmental Control (DNREC), Division of Fish and Wildlife conducts on-going inventories of natural communities as well as rare and declining species, (e.g., state and globally-rare plants, birds, insects, mussels, reptiles, and amphibians). It maintains a database, both electronic and manual, of its findings throughout the state. Learn more about the wildlife and plant communities in this watershed from the DNREC Division of Fish and Wildlife Conservation Programs.

In addition, the Division of Fish and Wildlife, working with the University of Delaware's Institute for Public Administration - Water Resources Center, maintains online databases about plants and plant communities in Delaware. Learn more about the plant communities in this watershed from the DNREC Division of Fish and Wildlife.
