A Watershed is the area that drains to a common waterway, such as a stream, lake, estuary, wetland, aquifer, or even the ocean. Our individual actions can directly affect the quality of the waters in our communities.

Anacostia WatershedThe Anacostia Watershed is part of the Chesapeake Bay watershed, 85% of which resides within Maryland and 15% within the District of Columbia. Its urbanized 176 square-mile drainage area is one of the most densely populated areas in the Chesapeake.

The Anacostia Trash TMDL was developed in 2010 to restore water quality by capturing or removing more than 600 tons of trash from the Anacostia watershed each year.

The Anacostia River has been highlighted nationally as an Urban Waters community project case study in the Mid-Atlantic Region.

Anacostia WatershedThe Chesapeake Bay is the largest estuary in the U.S., about 200 miles long, stretching from Havre de Grace, Maryland to Norfolk, Virginia. Its watershed encompasses six states and the District of Columbia.

The historic Chesapeake Bay nutrient and sediment TMDL was established in 2010 to restore clean water in the Chesapeake Bay and the Region's streams.

The Chesapeake Bay Program Exit EPA Click for Disclaimer is a unique regional partnership that has coordinated the restoration of the Chesapeake Bay and its watershed since 1983.

Delaware River Basin MapThe Delaware River Basin is 13,539 square miles and drains parts of New York, Pennsylvania, New Jersey and Delaware.  It rises in the Catskill Mountains and runs 330 miles to the Delaware Estuary. 15 million people rely on the Delaware River Basin for drinking, agricultural and industrial uses. The Delaware River Basin Commission (DRBC)Exit EPA Click for Disclaimer is an interstate governing body that jointly manages the water resources of the basin.

The Delaware Basin Source Water CollaborativeExit EPA Click for Disclaimer is a basin-wide partnership to identify and explore issues impacting water resource sustainability in the basin.

The Schuylkill Watershed Exit EPA Click for Disclaimer is part of the Delware River Basin and includes parts of 11 counties in southeastern Pennsylvania.

Ohio River Basin map

The Ohio River begins at the confluence of the Allegheny and the Monongahela Rivers in Pittsburgh, PA, and flows 981 miles until it meets the Mississippi River. The Ohio River basin is home to over 25 million people and includes parts of eleven states, three of which (Pennsylvania, Maryland, and West Virginia) are in the Mid-Atlantic Region.

The Ohio River Valley Water Sanitation Commission (ORSANCO)Exit EPA Click for Disclaimeris an interstate commission established to control and abate pollution in the basin.

Susquehanna River Basin map

The Susquehanna River basin is part of the Chesapeake Bay Basin and contributes half of the freshwater flow to the Bay. The Susquehanna itself has a 27,510 square mile drainage area from the states of New York, Pennsylvania, and Maryland.

The Susquehanna River Basin Commission (SRBC) Exit EPA Click for Disclaimer is an interstate watershed agency that coordinates water resources efforts of the three states and the federal government.

The Mid-Atlantic Region works to prevent and reduce pollution and provide habitat protection through an interdisciplinary watershed approach and a variety of federal, state, local, and watershed partnerships. We encourage the use of green infrastructure and other innovative approaches to protect, restore, and preserve watersheds.

Green Infrastructure News

Imagine strolling along a street shaded by trees, illuminated by solar-powered street lamps, on sidewalks lined with gardens that quickly soak up rainwater after a spring storm. Imagine a town that is training a local workforce to build these sustainable, green streets. Imagine a town where the new Triple Bottom Line - people, planet, profit - is the standard for local businesses.

The Green Streets, Green Jobs, Green Towns Partnership (G3) aims to stimulate the green jobs market and enable families to work where they live and play. Small to mid-sized communities can boost their local economies and protect water resources through the use of watershed planning, design and construction of stormwater best management practices.

The G3 Academy represents a virtual resource and a collaborative network of stewards, practitioners and sponsors. The G3 Academy offers community leaders, local stakeholders, and private and public entities easy access to technical, planning, policy, funding and job creation opportunities as it relates to the creation of green streets and green towns. The G3 Academy (PDF) (5pp, 678 KB) includes case studies (G3 Academy Honor Society), training and technical assistance (G3 Academy Studio), and resource materials (G3 Academy Library).

G3 Academy Honor Society

Many of our Mid-Atlantic towns and cities are paving the way with Green Streets!  Green streets integrate stormwater management practices and other sustainable features and are an important vehicle toward creating green, sustainable communities. Mayors, town administrators, town councils, community organizations and job training programs are the catalysts for greening streets, towns and businesses.

The G3 Academy presents several case studies, including recipients of the G3 grants, a funding opportunity supported by our partners the Chesapeake Bay Trust, Maryland Department of the Environment, Maryland Department of Natural Resources and EPA Region 3, Water Protection Division.

Watershed Resources Registry

The Watershed Resources Registry Exit EPA Click for Disclaimer is a national pilot to integrate land-use planning, regulatory, and non-regulatory decision making using the Watershed Resources Registrywatershed approach. Through a partnership of state and federal agencies, a GIS based targeting tool has been developed to analyze watersheds and identify the best opportunities for the protection of high quality resources, restoration of impaired resources, resource conservation and environmental resource planning, and improvement of stormwater management. The Registry aims to enable the characterization and prioritization of natural resources based within watersheds, and assist regulators and the regulated community to make timely & cost effective decisions based on sound watershed specific data. The WRR is also intended to integrate the Clean Water Act (CWA) authorities by facilitating implementation of CWA Sections 319, 401, 402, and 404, TMDL implementation practices, and multiple state programs.
