Inter-Fluve, Inc. is an environmental engineering firm that specializes in sustainable design, restoration and construction of river, lake, wetland, dam removal, and aquatic ecosystems. 

Since 1983, we have integrated natural sciences with water resources engineering to create long term sustainable design solutions for stream and river restoration.  Our design approach assesses natural and man-made conditions to provide a balance between human use and natural habitat.  We assist municipal agencies, non-profit organizations, private land owners, and land developers with watershed scale planning and with design and restoration of urban, rural and wild rivers, streams and floodplains.  With planning and analysis, we provide design-build and complete design-bid-build engineering services through construction oversight and performance monitoring.

Our projects result in minimal disturbance of existing habitat, and rapid recovery of aesthetics, geomorphic function and ecologic complexity. 

With over 1,300 projects—from large scale rivers and floodplains, watershed planning, dam removal, riverbank stabilization, habitat restoration, sporting properties, geomorphic assessments and water projects relicensing—our staff has the expertise: fluvial geomorphology, water resources engineering, aquatic and fisheries biology, hydrology, hydraulics, sediment, wetland ecology, green land development planning assistance, sporting properties planning and management, GIS, AutoCAD and graphic design.
