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.
Ophidiophobia is the irrational fear of snakes. Although the vast majority of snakes are completely harmless, they can startle people when you’re doing fieldwork in tall grass. Dress accordingly, and watch where you step. (Survey at Túuši Wána). #riverrestoration #snakes #surveying #touchet
For those of us in the Northern Hemisphere, today marks the first day of summer. And that can only mean one thing—field work! #hellosummer #wetlandvibes #waders #survey #riverrestoration #geomorphology
In recognition of Icelandic National Day, here's a story about river conservation from 1907.
Sigríður Tómasdóttir (1871-1957) grew up on her family's farm near the Hvítá River in southwest Iceland. She would occasionally guide travelers to Gullfoss, a waterfall that plunges over 100 feet into the canyon below. In 1907, a group of foreign investors rented the waterfall from local landowners, and planned to build a hydroelectric dam across the Hvítá River. This would have submerged the falls.
Sigríður took legal action to protect the falls. She would regularly walk the 75 miles to Reykjavík to meet with her lawyer, Sveinn Björnsson (who later became Iceland's first president). Although their legal efforts failed, Sigríður's cause gained popularity throughout the country, and the hydroelectric project was cancelled.
She is considered Iceland's first environmentalist, and a statue of her stands near Gullfoss to this day.

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
