Beaches are a Natural Resource

The sandy beaches along the Atlantic Ocean and Delaware Bay shorelines are valuable natural resources to the State of Delaware. The beaches were created by nature and continue to be shaped by wind and waves. The 1972 Beach Preservation Act (7 Del.C. Chapter 68) provides the authority to DNREC to enhance, preserve, and protect the


Macroalgae in Delaware’s Inland Bays

The water quality of Delaware’s Inland Bays is very important to outdoor recreational activities available for Delawareans and visitors alike. The Assawoman, Indian River and Rehoboth Bays provide a superb venue for fishing, boating, waterskiing and other related outdoor activities. However, like so many natural resources, these areas also suffer from the negative effects of


Landowner Protection Options

Approximately 45 percent of all wetlands in the state are located on privately owned lands, with the remaining wetlands found on both state and federal lands. With nearly half of Delaware’s wetlands found on private lands it is important for landowners to recognize the benefits wetlands provide and work towards conserving and preserving them.


The Delaware Wetlands Conference

The 2024 Delaware Wetlands Conference was a great success. The next event will take place in 2026. The conference planning committee is excited to integrate feedback and share new features for the upcoming conference. In previous years, this conference has brought together over 425 attendees, 75 different presentations

Chesapeake Bay Watershed Implementation Plan – Phase III

There have been three phases of Delaware’s Chesapeake Bay WIP. Delaware developed its Phase I WIP in 2010 and its Phase II WIP in 2012. Both the Phase I and Phase II WIPs describe actions and controls to be implemented by 2017 and 2025 to achieve applicable water quality standards. The Phase III WIP provides


Chesapeake Bay Watershed Implementation Plan – Phase I

Draft Phase I Watershed Implementation Plans (WIPs) were due to EPA on Sept. 1, 2010. Final plans were submitted on Nov. 29, 2010. Following the release of Delaware’s Draft Phase I WIP, numerous comments and questions from both EPA and various stakeholder groups within the watershed were submitted.


Chesapeake Bay Watershed Implementation Plan – Phase II

Delaware’s Draft Phase II Watershed Implementation Plan for the Chesapeake Watershed was submitted to the EPA on Dec. 15, 2011. EPA reviewed the document and provided comments in Feb. 2012. Public comments were accepted through March 21, 2012. All suggestions were considered and the document was modified accordingly.


Events and Workshops

The DNREC Nonpoint Source Program has hosted and participated in a series of events, workshops, and presentations designed to promote and support improvements to the quality of Delaware’s waterways.

Chesapeake Bay Watershed Implementation Plan

Delaware is among six Chesapeake Bay Watershed states – along with Maryland, Virginia, West Virginia, Pennsylvania, and New York – and the District of Columbia committed to a federal-state initiative to develop a pollution “diet” that will help restore the water quality of the Bay and its tidal waters by 2025.

Properly installed and functioning practices and technologies reduce local flooding, protect sources of drinking water, ensure against the collapse of stream


Watershed Plans and Strategies

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 program


Pollution 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 get


Integrated Report: 305(b) Report and 303(d) List

Section 305(b) of the Federal Clean Water Act requires that states and other entities prepare and submit Watershed Assessment Reports to the US EPA on April 1 of every even-numbered year.

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 the


Protecting Our 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: A


Surface 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 for

    Information About Vibrio Bacteria

    Vibrio are bacteria that occur naturally in brackish waters such as the Delaware Bay, the Inland Bays and tributaries, especially during warm weather months. Vibrio infections are relatively rare in Delaware and nationwide. However, when Vibrio or other bacteria come into contact with an open wound, they can cause serious infections. Vibrio infections can be


    What is a Red Tide?

    “Red Tide” is the common term for a particular type of harmful algal bloom made up of large concentrations of toxic red dinoflagellates called Karenia brevis (K. Brevis). These are tiny red-colored, naturally-occurring aquatic microorganisms which, in sufficient concentrations, can cause a reddish tint to the water. At very high concentrations, they can cause toxic
