What is an estuary?
An estuary is where fresh water meets saltwater. They are unique environments that sustain diverse plant and animal life — and they are key resources for our economy. Explore what defines an estuary's boundary, what species you will find within the seagrass, how dams and pollution affect our coasts, and much more below. RAE provides the resources and tools you need to understand our estuaries, and most importantly, how to protect them.
