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 130+ 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.
Thanks to Sonoma Water for sharing this video highlighting more than a decade of working with private landowners and resource agencies in the Dry Creek valley to restore habitat for endangered Coho and Steelhead. To date three miles of Dry Creek have been restored by Sonoma Water with another 3 miles to be constructed in close collaboration with The Army Corps of Engineers.
Inter-Fluve has completed over 2,400 projects. Here’s where we’ve been working.
Today is World Fish Migration Day! A lot of our projects involve fish passage in one way or another, and it's always exciting to see the results. After removing some barriers and constructing a new channel at Childs River in Mashpee, Massachusetts, our project partners have sent us these photos of the first few fish of the migratory season. #fishpassage

Described by John J. Audubon as "a vigorous and robust bird," the common merganser is a large duck found near water throughout the Northern Hemisphere. The word "merganser" is a combination of the Latin words "mergus" (a generic term for waterfowl) and "anser" (meaning "goose"). In the UK, they are commonly known as "goosanders," and they were known to French speakers in Louisiana as "becs-scie-de-mer" (or "sea sawbills"). #audubon #oregon #merganser #duck #goosander
Lampreys and people have an interesting history. They were kept as pets by Ancient Romans, and are considered a delicacy in parts of Europe, Asia, and the Pacific Northwest. A lamprey pie weighing 20 pounds was served at the coronation of Queen Elizabeth II.
In the Midwest, we often think of lampreys as invasive species that are wreaking havoc on native fish in the Great Lakes. However, this is not the full story. There are a few native species of freshwater lampreys present in the area that are non-parasitic and completely harmless. Here is a group of native lampreys building a redd (like a nest) to deposit their eggs. After mating, the adults, which are unable to eat, will die. Soon their algae-eating larvae will hatch, and the cycle will continue. #lamprey #driftless #riverrestoration #fisheriesbiology

Wangarĩ Muta Maathai, the first African woman to win the Nobel Peace Prize, was born on this day in 1940. A leading ecofeminist, Maathai founded the Green Belt Movement to organize women in rural Kenya to plant trees in order to combat deforestation, earn income, and stop soil erosion. This combination of poverty reduction and environmental conservation has since been replicated around the world. #OnThisDay #intersectionalenviromentalism #restorationscience #bioengineering
