Dam Removal and Fish Passage Restoration, Design and Construction
NTH led a multidisciplinary team of engineers, biologists, geologists, and environmental scientists with this important project. The project involved demolition and removal of three low-head dams along the channelized stream, design of in-stream rock control structures to maintain stream stability, and vegetating the stream bank and rock slopes along the stream.
The design team firms and their roles on the project included:
The project included field investigation and surveying, stream flow and fish-passage modeling, engineering design for the removal of the three dams and compensation for absence of the dams with in-stream rock-riffle structures. The in-stream structures help maintain stability of the stream bed load and control sloughing of the streambank.
After a bidding process, Mark Haynes Construction was selected to complete the construction, largely because of their experience in completing similar challenging stream restoration projects and their specialty equipment that enable them to access the three dam locations.
Construction management activities by the NTH team included:
