Emergency Response Services

If a spill occurs that impacts river, wetland, or lake environments, we are available to assist with the emergency response planning, coordination, and construction of remediation and restoration measures. We are experienced in working with response teams and Joint Restoration Committees, and understand processes, and regulations important to federal, state, city, tribal, private and corporate representatives involved in time-sensitive emergency environments.

Design and Construction of Side Channel Creation Services

Side channels–optimum habitat for salmon and steelhead during high-flow–were disconnected from the Clackamas River beginning in the early 20th century as a result of the channel becoming heavily incised. Two of the largest contributing factors were a new floodplain gravel mine and an upstream dam.

River Headwaters Restoration & Sawmill Dam Removal Services

Historically, the Eel River flowed uninterrupted to the Atlantic, supporting fish, wildlife, and wetland communities. Beginning in the early 1800s, the Eel River watershed (and others in Massachusetts with similar characteristics) were severely compromised when they were converted to cranberry bogs, which involved removing trees, channeling streams, and building berms and dams to control water.

Picha Creek Channel Restoration Services

Inter-Fluve was introduced to Picha Creek while walking 125 miles of the Sand Creek and Credit River in Minnesota during a watershed-level assessment. At that time, we identified more than 200 restoration projects by ranking them on a 1-11 scale. Picha Creek ranked at the top for restoration potential. Increased rainfall, tilling, and development pressures in the upper watershed were leading to channelization, resulting in river channel incisions up to 10 feet. Significant sediment loads were also being released into the system, with no sign of equilibrium.

Minnehaha Creek Natural Channel Restoration Services

We designed and provided construction oversight for 2,000 feet of meandering wetland channel and an off-line pond adjacent to Methodist Hospital, near Minneapolis, Minnesota. The project concept, coined “Healing Spaces,” emerged in the early 2000s, when Methodist Hospital embraced the nearby Minnehaha Creek and wetland as an asset instead of a barrier. Instead of building a parking lot, the hospital committed to utilizing the creek as a human-and-nature healing experiment.
