About Estuaries
Estuaries are places where freshwater from a river mixes with saltwater from the sea. Estuaries come in all shapes and sizes. They are often known as bays, sounds, lagoons, harbors, or inlets (note though that not all water bodies by those names are necessarily estuaries; the defining feature of an estuary is the mixing of fresh and salt water, not the name.)
National Estuary Program (NEP) Overview
A study* found the networks in NEP areas span more levels of government, integrate more experts into policy discussions, nurture stronger interpersonal ties between stakeholders, and create greater faith in the procedural fairness of local policy than other comparable estuaries.
*Building Consensual Institutions: Networks and the National Estuary Program, M. Schneider et. al., American Journal of Political Science, Vol. 47. No 1, January 2003
The NEP was established under Section 320 of the 1987 Clean Water Act (CWA) Amendments as a U.S. Environmental Protection Agency (EPA) place-based program to protect and restore the water quality and ecological integrity of estuaries of national significance. Section 320 of the CWA calls for each NEP to develop and implement a Comprehensive Conservation and Management Plan (CCMP). The CCMP is a long-term plan that contains specific targeted actions designed to address water quality, habitat, and living resources challenges in its estuarine watershed.
Each NEP has a Management Conference (MC) made up of diverse stakeholders including citizens, local, state, and Federal agencies, as well as with non-profit and private sector entities. Using a consensus-building approach and collaborative decision-making process, each MC works closely together to implement the CCMP. The MC ensures that the CCMP is uniquely tailored to the local environmental conditions, is based on local input, and supports local priorities.
Currently there are 28 estuaries located along the Atlantic, Gulf, and Pacific coasts and in Puerto Rico that have been designated as estuaries of national significance. Each NEP focuses it work within a particular place or boundary called a study area which includes the estuary, and surrounding watershed.

Each of the 28 National Estuary Programs was charged with developing and implementing a Comprehensive Conservation and Management Plan (CCMP) which establishes priorities for activities, research, and funding for the estuary. The CCMP serves as a blueprint to guide future decisions and actions and addresses a wide range of environmental protection issues including water quality, habitat, fish and wildlife, pathogens, land use, and introduced species to name a few. The CCMP is based on a scientific characterization of the estuary and is developed and approved by a broad-based coalition of stakeholders.

Challenges and Approaches
Challenges facing our Estuaries and NEP Approaches for Restoration
Tackling common Environmental Problems
Charlotte Harbor National Estuary Program
San Francisco Estuary Partnership
Tampa Bay Estuary Program
Estuaries face a host of common challenges. Because we love and depend on the water, more than half of the people in the United States live within 100 miles of the coast, including on the shores of estuaries. And more and more people are moving to these areas. Coastal communities are growing three times faster than counties elsewhere in the country.
Conditions
NEPs are required to monitor the effectiveness of their management activities to address estuary-specific priority problems. In addition, the Clean Water Act requires EPA to report periodically on the condition of the nation's estuarine waters. To meet those mandates, EPA and each NEP monitor conditions in estuarine/coastal waters.
As stated in the 2007 National Estuary Program Coastal Condition Report, the NEP estuaries are rated "fair" and scored equal to or higher than all other US estuaries combined despite increasing population pressures in the 28 estuarine watersheds. This rating is based on four key indicators of ecological health: water quality, sediment quality, benthic community condition, and fish tissue contaminants.
Individual NEPs have also worked with their many partners to collect, compile and analyze monitoring data producing "State of the Bay" reports about their estuaries every 3-5 years. Since these data are collected over a longer time period and from more sampling sites than are depicted in the NEP CCR, they provide a more comprehensive picture of NEP estuarine conditions than does the NEP CCR.
National Estuary Program Coastal Condition Report
You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more.
The report is based on available monitoring data for the period 1997-2003 collected by Federal agencies, State, Regional and local organizations. For each of these four key indicators, a score of good, fair, or poor was assigned to each NEP. These ratings were then averaged to create overall regional and national scores, illustrated in the adjacent map, using "traffic light" color scoring.
The ratings developed in the report are based solely on the National Coastal Condition Assessment data. The individual NEPs collect other monitoring data over a longer time period and at more sampling stations that further enhance the picture of conditions in their estuaries.

Environmental Indicators
To gauge an estuary's health, each NEP develops environmental indicators—"specific, measurable markers that help assess the condition of the environment and how it changes over time" (see Indicator Development for Estuaries, EPA 842-B-08-004 September 2008). For each environmental indicator, a quantitative or qualitative measure is developed based on the goals and objectives of a CCMP, which in turn reflect the priorities of local stakeholders. These indicators can include water and sediment quality, land use, living resources, and habitat among many others.
Volunteer Monitoring
Citizen volunteers play an important role when it comes to monitoring conditions in our estuaries, particularly water quality conditions. See the Volunteer Estuary Monitoring Manual to learn how to establish and maintain a volunteer monitoring program, as well as how to work effectively with volunteers and ensur their safety.

Lessons from the NEP
EPA's place–based National Estuary Program provides important lessons for other coastal communities working to restore and protect their watersheds. The following lessons learned are drawn from the 28 individual NEPs and documented in the documents shown below.
NEP Lessons Learned
- Effective governance (PDF) (15 pp, 1.1MB, About PDF) structures and by-laws promote open discussion, cooperation, and information sharing that leads to consensus and the efficient use of resources.
- Science and local knowledge helps identify the causes and approaches (PDF) (19 pp, 1.1MB, About PDF) to remedy environmental challenges facing coastal areas.
- Comprehensive plans (PDF) (13 pp, 1.4MB, About PDF) include long-term goals for the estuary, major challenges, and action developed with broad wide stakeholder input and updated regularly.
- Effective implementation (PDF) (25 pp, 927K, About PDF) requires clear, realistic, and measurable definitions of success; a diversity of funding sources; and broad public support.
Evaluating NEP Progress
In order to assess NEP progress made toward achieving their long-term goals, EPA conducts a Program Evaluation for each NEP. EPA developed NEP Program Evaluation Guidance that provides EPA and the NEPs with direction on how to assess the effectiveness of NEP actions. The Guidance presented below includes performance measures, describes a process for conducting site visits, and provides a feedback loop which helps ensure that recommendations for improvement are implemented.
