Basic Information about Estuaries | US EPA
An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean. Estuaries, and their surrounding lands, are places of transition from land to sea.
What is an estuary? Estuaries Tutorial - National Ocean Service
Estuaries are bodies of water and their surrounding coastal habitats typically found where rivers meet the sea. Estuaries harbor unique plant and animal communities because their waters are brackish—a mixture of fresh water draining from the land and salty seawater.

How to get involved in the National Estuarine Research Reserve?
Take action and get involved! Volunteer at your nearest National Estuarine Research Reserve. Organize a stream or beach cleanup. Encourage your local newspaper to write a story, or ask an expert to speak at your community organization or school.
How to keep chemicals from ending up in waterways?
Plain soap and water does the job and can keep harmful chemicals from ending up in nearby waterways. Use native plants. Garden and landscape with plants native to your areas and reduce the need for watering and fertilizing. Collect rainwater.
Why do we protect estuaries?
Why we protect estuaries. Estuaries are valuable environmental assets that are under increasing pressure. With more than 80% of New South Wales’s population living on or near the coast, coastal local government areas are rapidly developing and growing faster than those elsewhere in the State.
Why is it important to manage estuaries?
We manage estuaries to protect them from threats including coastal development and natural weather events. The health and integrity of estuaries is vital in maintaining environmental, social and cultural values and ecosystem services. This strongly benefits the communities that interact and depend on them.
How many estuaries are there in NSW?
We have collected data on the physical characteristics of 184 estuaries in NSW. We continue to measure and record estuary conditions, including tidal flow and water and quality.
What are the risks of estuaries?
Estuaries are at risk from extreme weather events. Climate change projections suggest that extreme rainfall events will increase in frequency and intensity. Extreme rainfall events and large damaging storms can cause flooding in rivers and estuaries as well as flash flooding.
What is coastal and estuary grants?
Technical and financial assistance is available for managing risk s from coastal hazards, restoring coastal habitats and improving estuary health through our Coastal and Estuary Grants Program. We also provide councils, public authorities and communities with advice about preparing a coastal management program.
Why are estuaries important?
Estuaries are important natural places. In addition to essential habitats for birds, fish, insects, and other wildlife, estuaries provide goods and services that are economically and ecologically indispensable, such as commercial fishing and recreational opportunities.
How are estuaries protected from the ocean?
While strongly affected by tides and tidal cycles, many estuaries are protected from the full force of ocean waves, winds, and storms by reefs, barrier islands, or fingers of land, mud, or sand that surround them . The characteristics of each estuary depend upon the local climate, freshwater input, tidal patterns, and currents.
How do estuaries benefit the economy?
Estuaries are often the economic centers of coastal communities. Estuaries provide habitat for more than 75 percent of the U.S. commercial fish catch, and an even greater percentage of the recreational fish catch. The total fish catch in estuaries contributes billions of dollars a year to the U.S. economy.
How does the fish catch in estuaries contribute to the economy?
The total fish catch in estuaries contributes billions of dollars a year to the U.S. economy. The fishing industry depends on healthy estuaries to provide essential nursery areas for many commercially important fish and shellfish species. (Photo: Hansje Gold-Krueck)

Why are estuaries important?
Estuaries provide places for recreational activities and scientific studies. Estuaries are an irreplaceable natural resource that needs to be carefully monitored so that the animals and plants that depend on them are thriving. Thousands of species of birds, mammals, fish and other wildlife live in and around estuaries.

Thousands of species of birds, mammals, fish and other wildlife live in and around estuaries. They depend on them to live, feed and reproduce. Many marine organisms, especially fish used in commercial fishing, depend on estuaries at some time in their life.
What happens when water drains from upstream areas?
Water draining from upstream areas bring down sediments, nutrients and other pollutants to estuaries. As the water flows through the wetlands and marshes, all the pollutants are filtered out.
How do estuaries protect coastal areas?
They stabilize shorelines and protect coastal areas, inland habitats, and human communities from floods and storm surges from hurricanes. When flooding does occur, estuaries often act like huge sponges, soaking up the excess water.
Why are estuaries important to the ecosystem?
One reason that estuaries are such productive ecosystems is that the water filtering through them brings in nutrients from the surrounding watershed. A watershed, or drainage basin, is the entire land area that drains into a particular body of water, like a lake, river or estuary.
Why are estuaries so fertile?
For this reason, estuaries are some of the most fertile ecosystems on Earth. Yet, due to the pollutants they extract from waters running through them, they may also be some of the most polluted as well.
What are the services of ecosystems?
Ecosystem Services are the benefits nature provides to people. In addition to the ecosystem services previously discussed (economic, cultural, and ecological benefits), estuaries provide water filtration and habitat protection. Salt marshes are one type of estuarine habitat that acts like an enormous filter, removing pollutants such as herbicides, ...
What are the habitats of estuaries?
Habitats associated with estuaries, such as salt marshes and mangrove forests, act like enormous filters. As water flows through a salt marsh, marsh grasses and peat (a spongy matrix of live roots, decomposing organic material, and soil) filter pollutants such as herbicides, pesticides, and heavy metals out of the water, ...
What is salt marsh?
Salt marshes are one type of estuarine habitat that acts like an enormous filter, removing pollutants such as herbicides, pesticides, and heavy metals out of the water flowing through it.
