For over a decade, RDG has provided fish passage and stream restoration services for the Long Tom Watershed Council (LTWC). We have developed long-term relationships with private landowners, council staff, and regulatory agencies to maximize the LTWC’s restoration dollars on the ground.  Our services include working with the LTWC to develop restoration alternatives at fish passage barriers including relict dams, culverts, and other obstructions within the watershed. We have worked closely with LTWC staff and integrated them into our field work efforts to help reduce costs while providing a high level of service and expertise. Our projects have included the following restoration services:

  • Dam removal with channel restoration
  • Culvert replacement for fish passage
  •  Stream restoration
  •  Large wood habitat restoration
  •  Bridge planning and analysis

In addition to designing restoration and fish passage projects, we provide permitting and construction administrative services. Typical assistance includes writing specification packages for bidding, on-site construction observations, and project as-built surveys to establish long-term monitoring reference points.
