What is a wetland?

A wetland is simply an area of land that is wet during the growing season. To be a true wetland it needs to have three things: wetland plants, wetland soils, and evidence of water at or near the surface. 

Nearly 25 percent of Delaware is covered in wetlands. To learn more about the state's wetlands, please visit the Wetland Types website.

Why are wetlands valuable?

Wetlands PURIFY our drinking water supplies by filtering pollutants from waters upstream.

Wetlands PROVIDE habitat and shelter for rare and commercially important plants, fish, and wildlife.

Wetlands act like sponges to PROTECT your home from flooding. One acre of wetlands can hold up to 1 million gallons of stormwater.
