Our Work
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.
Inter-Fluve has completed over 2,600 projects. Here’s where we’ve been working.
Vinegar to Vincent Habitat Restoration
Kachess River Restoration Project
2024 was a record-tying year for dam removals, with 108 dams removed and 2,528+ miles of river reconnected across the U.S. We`re thrilled to celebrate this momentum with @americanrivers and highlight our work on the Washburn Dam removal in New Hampshire.
Removing outdated dams restores fish passage, improves water quality, and enhances public safety. Thanks to this project, the river is flowing freely again, benefiting wildlife and local communities.

Our very own Mark Pranckus will be presenting at the Upper Midwest Stream Restoration Symposium in Dubuque, Iowa, on Tuesday, February 25.
Mark’s presentation, titled “Looking Downstream to Avoid Stumbling Upstream – How Past Projects Can Be Used to Prepare for Future Stream Restoration Challenges,” explores the importance of learning from past projects to tackle future challenges more effectively. In a field where it’s easy to “complete and move on,” Mark is pushing us to reflect and build on what we’ve learned for smarter, more sustainable solutions.
If you’re attending the symposium, don’t miss this insightful session! Let’s keep the conversation flowing and work together to make a lasting impact on our waterways.

The new boardwalk at Mirror Pond in Bend, OR, now provides full ADA accessibility along a previously challenging section of trail. Inter-Fluve completed hydraulic modeling to predict sediment depositional and scour patterns, inform planting plans of native riparian and aquatic plants, and support design of habitat for native fish species. Congrats to @HDR and all involved for making this happen, and to Engineers and Geoscientists British Columbia for the nice write-up. #SustainableDesign #AccessibilityForAll #TrailImprovements
Happy Holidays! Here are some of this year`s project highlights from Maine to British Columbia. #riverrestoration #environmentalscience #environmentalengineering #habitatrestoration #rewilding
