Dam Removal & Fish Passage

Fish passage barriers across the United States are being removed or modified to help fish and wildlife, improve safety and boost recreation. We’ve worked on 150+ dam removals, removed hundreds of culverts, and developed best practices resources for bridge crossings.

Estuary Restoration

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

Urban

Beginning with the daylighting of Tanner Creek in Portland (1992), we’ve been collaborating with urban planners and landscape architects to restore urban streams from coast to coast in the US and abroad.

Inter-Fluve has completed over 2,400 projects. Here’s where we’ve been working.

It's #nationalestuariesweek again! When working in these delicate and important ecosystems, we take extra care to minimize construction impacts. In this case, it involved using barges to transport equipment. #estuary #pnw #construction #ecology #waterresources #barge #bargelife ...

NOAA and American Rivers teamed up to remove Bloede Dam on the Patapsco River, restoring vital habitat for migratory species. A recent study shows river herring now using the reopened area.

Today is World Wetlands Day. Instead of talking about how important and beautiful wetlands are, we want to ask you a question. This picture shows a scene that is common in many agricultural areas. A wetland was drained into a ditch, and over time the ditch has started to look and act like a stream. Unlike our other stream restoration projects, there likely was not a channel there in the first place. So, what does it mean to "restore" this area? Does it mean bringing back the wetland and losing the stream? Or does it mean improving instream and riparian habitat as if the stream has always been there?
