Dam Removals

From California to Maine, dams across the United States are being removed to help fish, improve safety and boost recreation. We’ve worked on over 100 dam removals and performed construction oversight on over 35.

Large Wood Design

There are rivers that move wood, and wood that moves rivers. We do both. Placing large wood structures improves aquatic habitat conditions, can assist in providing reliable bank protection, and enhances the structural and hydraulic complexity of the channel.

Floodplain Reconnection

Floodplains provide habitat for fish and wildlife, storage for floodwaters, clean our waters, and provide space for rivers to move. We examine historical and contemporary river corridor to strategically reconnect floodplains.

Fish Passage

Opening watersheds is a fundamental and cost effective first step to encourage the return of fish and aquatic species to their native habitats.

Off-Channel Habitat

We design off-channel habitats that provide the right velocity, in the right place, for the right fish.

Watershed Planning & Long-Term Implementation

To understand where a river is going, we need to know where it has been. Assessments are the foundation of a stream habitat restoration strategy and lead to projects in the ground.

Estuary Restoration

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

Wetlands & Peat Bogs

Holistic ecological restoration of cranberry bogs to native stream and wetland ecosystems was pioneered by Inter-Fluve. Today, we’re applying lessons learned to New England cranberry farms and Pacific Northwest estuaries.

Urban & Planning

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

Tools for Visual Communication

To understand where a river is going, we need to know where it has been. Assessments are the foundation of a stream habitat restoration strategy and lead to projects in the ground.

Technical Design Guidelines

In the early 1980s, there were no instruction manuals for the emerging river restoration industry. Today we regularly contribute to technical design guidelines to elevate industry best practices with various audiences and public engagement strategies.
