Pocomoke Watershed Wetland Assessment
The Pocomoke watershed is partly located in southern Sussex County and extends south into Maryland. It encompasses 138,125 acres of land in both states. Though most of the Pocomoke watershed is agricultural land, this area contains Category One wetlands, which are unique and ecologically significant freshwater areas.Submerged Aquatic Vegetation Program
Submerged aquatic vegetation (SAV), also known as seagrass, bay grass or underwater grasses, is critical to the health of aquatic ecosystems. It provides habitat, food and nursery grounds for commercially and recreationally important fish and shellfish and helps improve water quality by trapping sediments, absorbing excess nutrients and mitigating shoreline erosion.

DNREC has developed a comprehensive plan to address toxic contaminant impairments in the C&D Canal watershed.Total Maximum Daily Loads and Advance Restoration Plans
When monitoring reveals that waterways do not meet Delaware’s water quality standards for their intended uses, as defined in Delaware’s Surface Water Quality Standards, they are added to a list of impaired waterways (Delaware’s 303(d) List). For each impaired waterway, the Federal Clean Water Act (CWA) requires states to develop Total Maximum Daily Loads (TMDLs)Swimming Advisory Caution
The DNREC Recreational Water Program monitors bacterial water quality at established sampling sites throughout the state from May through September. If bacterial sampling results exceed state standards, DNREC issues swimming advisories for Atlantic Ocean beaches, as well as for Delaware Bay beaches south of and including Lewes Beach and for Lake Como in Smyrna.Source Water Assessment and Protection

Wetlands across the state of Delaware face many challenges. However, there are opportunities to combat specific issues and to restore and protect Delaware’s wetland resources. The DNREC Wetland Monitoring and Assessment Program is developing strategies, specific to Delaware’s different watersheds, to identify and pursue those opportunities. The wetland restoration strategies will helpChester-Choptank Watershed Wetland Assessment
The Chester-Choptank watershed is located partially in Kent County and partially in New Castle County, where it encompasses 113,944 acres of land. Unlike most of Delaware’s watersheds, the Chester-Choptank drains to the Chesapeake Bay. The Chesapeake Bay drainage basin in Delaware, including the Chester-Choptank watershed, provides an estimated $3.4 billion in ecosystem goods and services.PFAS Investigation Sites

Numerous documents describing plans or strategies for water quality and watershed improvements have been developed over the years. Some of these efforts originated through the Tributary Action Team process while others came through other initiatives. All of the documents below can be considered watershed management plans for the Water Quality Improvement Projects grant programPollution Control Strategies and Tributary Action Teams
A 1997 federal court case required Delaware to set pollution limits for its waterways. These limits are called Total Maximum Daily Loads or TMDLs, a term you will hear a lot in water pollution discussions. In order to meet these new pollution limits, we are identifying ways to reduce water pollution. Usually, citizens don’t getIntegrated Report: 305(b) Report and 303(d) List

Whole Basin Management
Beginning in the 1990s, the Department of Natural Resources and Environmental Control (DNREC) took a different approach to assessing, managing, and protecting Delaware’s natural resources. This approach, known as Whole Basin Management, encouraged the various programs throughout DNREC to work in an integrated manner to assess different geographic areas of the state defined on theProtecting Our Waterways
There are many things each of us can do to help reduce nutrient and sediment pollution entering Delaware’s waterways. Our efforts will not only help protect the environment, but in many cases, when you lend a hand to protect our waterways, you will also find that you’re adding beauty to your yard,Water Quality Monitoring
Delaware’s bays, ponds, streams, and rivers are monitored on a regular basis to assess the quality of Delaware’s surface waters. Much of the monitoring is done by DNREC, though other groups, including federal agencies, academic institutions, and citizen volunteer monitoring programs, also contribute to these efforts.Inland Bays Pollution Control Strategy
The Inland Bays Pollution Control Strategy (PCS) and accompanying regulations were finalized in Nov. 2008. This strategy is designed to improve the water quality of the bays (Rehoboth Bay, Indian River Bay, and Little Assawoman Bay), as well as the rivers, streams, and ponds that drain to the bays. ADVISORY: ASurface Water Quality Standards
The National Clean Water Act of 1972 set in place a program that is intended to restore the chemical, physical, and biological integrity of the nation’s waters. To reach these goals, a series of steps were mandated by Congress for the Environmental Protection Agency and the individual States to take. The first step was forPromoting Shellfish Safety
To ensure the safety of Delaware’s shellfish growing areas, it is important that residents and visitors help maintain good water quality and limit pollution while recreating in or near shellfish growing areas.Contact Us
