Abstract The Clark Fork and Bitterroot Rivers CMZ was completed in 2021. Approximately 69 miles of the Clark Fork River and 22 miles of the Bitterroot River were mapped. Clark Fork River and Bitterroot River banklines as digitized on 2011 aerial photography. The bankfull channel reflects the active channel area that is comprised of unvegetated substrate, and its boundaries are delineated as the boundary between open channel and woody vegetation stands, terrace margins, or bedrock valley wall. The project was sponsored by Missoula County. The work was performed by Applied Geomorphology and DTM Consulting.
Purpose Define the composite Channel Migration Zone for the Clark Fork and Bitterroot Rivers (Missoula Area).
Supplemental Information
The corridor delineations presented in this geodatabase are intended to provide a basic screening tool to help guide and support management decisions. The expanse of the project area requires that the results are broad-scale in nature, and therefore less precise than highly detailed site-specific analyses. The results are unequivocally not intended to replace or override site-specific assessments; conversely, they are intended to highlight areas that would warrant such assessments as necessary.
