River Island Channel & Floodplain Restoration

Metro, a regional government body, contracted Inter-Fluve to restore an abandoned gravel mine on the Clackamas River. In 1996 a 100-year rain-on-snow flood event caused the mainstem Clackamas River to breach a levee and flow through this active gravel mining operation. Goals of the project included: to strategically implement restoration actions in areas where existing processes are insufficient to create or maintain highly functioning habitats, restoring perennially hydrologic connectivity to tributary habitats, and supporting multiple values including salmonids, stillwater species, and wildlife habitat, riparian and floodplain forests, water quality and recreation.

Bloede Dam Breached

Bloede Dam, the first dam on Maryland's Patapsco River, was loaded with explosives and breached on September 11, 2018 after 10 years and millions of dollars. This exciting step improves fish passage for several fish species, eliminates a public safety hazard, and improves recreational opportunities in the surrounding state park.
