Brackish bodies of water in estuaries have a higher amount of salinity, or salt content, than fresh water, but less than the sea.

An estuary is often referred to as a bay or a sound.

Because Delaware is largely defined by its coastal ecology, water quality and the health of its wetlands are conservation priorities for the state. Many of the state’s rivers and estuarine water sources are contaminated by bacteria as well as residential and urban pollution. The Delaware Wetlands Conservation Strategy is a collaborative effort that monitors wetlands in the state and helps to restore these areas for the enhancement of wildlife habitats and ecological benefits associated with wetlands, including the filtration and purification of water sources, the reduction of flooding, and the promotion of wetland education and biodiversity in the state.
