Prime Hook National Widllife Refuge

Tidal marsh at the Prime Hook National Wildlife Refuge in Delaware has been degraded by impounded freshwater drowning out marsh plants, as well as salt water intrusion from storm events. To reduce impounded water and restore functioning salt marshes, 30 miles of channels were dredged across 4,000 acres of tidal marsh. The channels mimicked historic locations and allow for water exchange. Sediment from the dredged channels was sidecast to help the marsh gain elevation and reduce plant stress. This project was funded through the Hurricane Sandy Disaster Relief Act of 2013 through the Department of Interior.
