Smith, D. and Ramsden, K., 2006. Illabot Creek Habitat Restoration Feasibility Study. Skagit River System Cooperative, La Conner, WA. pp. 87.

Illabot Creek is a very productive tributary of the Skagit River that supports populations
of Chinook, chum, coho, and pink salmon, native char and steelhead trout. Much of the
watershed has already been protected or restored. However, there are a number of habitat
impacts in the floodplain and alluvial fan reach that are limiting the full fish production
potential. The purpose of this feasibility study is to evaluate present habitat conditions,
identify specific habitat impacts on the floodplain or alluvial fan of Illabot Creek, and
develop and evaluate habitat restoration projects that could address those impacts. This
report includes general information about the Illabot Creek watershed and the fish use in
the area, a review of historic channel conditions from aerial photographs, a
characterization of current habitat conditions, and a detailed assessment of habitat
impacts caused by sediment, riparian vegetation, fish passage, and hydromodification.
The final section presents alternatives for addressing each of the impacts identified.
