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 2,600 projects. Here’s where we’ve been working.

This might look like a Halloween decoration, but decaying salmon play a key role in nourishing the lush forests on Taan (Prince of Wales Island) and throughout the Pacific Northwest. Their final journey brings vital nutrients to the towering trees and rich ecosystems of the PNW.

Fat Bear Week at Katmai National Park celebrates some of the most resilient and adaptable wildlife, and we’re excited to take this opportunity to showcase our work supporting ecosystems in Alaska.

At Inter-Fluve, we’ve been working in Alaska for decades to replace culverts and improve fish passage, ensuring that salmon can reach their spawning grounds and help support the health of the entire ecosystem—including the bears!
