Project Description

Estuaries are dynamic ecosystems where oceans, rivers and human economies converge; they’re also critical to rearing grounds for fish and wildlife. Across the country, we’re reconnecting and restoring these habitats.

These former tidal wetlands at Kerry Island were impacted by diking, ditching, culvert installation, grazing, and vegetation clearing. We removed levees to restore wetland ecosystem conditions and functions.

Levees were breached at Kerry Island, reconnecting floodplains to the estuary.

Construction equipment accessed the site by barge to minimize impacts to existing wetland vegetation.

The Wallacut River flows into Washington State’s Baker Bay near the mouth of the Columbia River (Pacific Ocean seen in the distance). Restoration efforts at the site included levee removal to reconnect tidal channels, sloughs and wetlands to the estuary.

Four levee breaches reconnected the East Fork Lewis River to a 450-acre tidally-influenced floodplain wetland.

Bridges constructed over the breaches maintained access along a county trail.
