This proposal is the first phase of what will likely be a large multi-phase restoration project. It includes final design and construction to remove infrastructure on Barnaby Slough to improve flow and restore fish passage, and design and construction for culvert projects that will restore fish passage and reduce flooding problems for residents along Martin Road. The Barnaby Reach of the Skagit River extends from the mouth of Illabot Creek downstream to the Sauk River, a distance of over four miles. Historically the river migrated across a broad floodplain in this reach, creating an extensive network of sloughs, wetlands, ponds, side channels, and other off-channel habitats. These types of floodplain habitats provide important spawning and rearing for Chinook salmon and other species. Unfortunately the floodplain in the reach has been degraded with dikes, culverts, and other infrastructure associated with a hatchery facility that is no longer in operation. Much of the land in the Barnaby Reach is in conservation or public ownership, which creates a unique opportunity for significant floodplain restoration. A partnership including the Skagit River System Cooperative, Department of Fish and Wildlife, Seattle City Light, and The Nature Conservancy has been working for almost a decade with the nearby community to restore habitat conditions and reduce flooding and erosion risks in the Barnaby Reach.
