Channel Migration Zones
Montana Channel Migration Zone Projects - Beaverhead River
The Beaverhead River Channel Migration Zone (CMZ) was completed in 2017. The project developed approximately 83 miles of mapping for the Beaverhead River from its beginning at Clark Canyon Dam, downstream to its confluence with the Big Hole River in Twin Bridges. The project is part of a larger effort to create CMZ mapping for approximately 440 miles of river in the Missouri River headwaters.
The work was funded through a 2013 Montana Department of Natural Resources and Conservation (DNRC) Reclamation and Development Grants Program (RDGP) titled Upper Missouri Headwaters River/Flood Hazard Map Development. The project was administered by the Ruby Valley Conservation District, but includes input and review from stakeholders associated with each of the mapped rivers. The work was performed by by Applied Geomorphology and DTM Consulting.
