Channel Migration Zones

Montana Channel Migration Zone Projects - Lower Ruby River

The Lower Ruby River CMZ was completed in 2010 from the Ruby Reservoir to its confluence with the Beaverhead River.  The project was sponsored by the Ruby Valley Conservation District and the Montana Department of Environmental Quality and completed by Applied Geomorphology and DTM Consulting.

In 2017, the mapping was updated as part of the Clear Creek CMZ project to include detailed bank protection mapping developed by the Natural Resource Conservation Service (NRCS) in 2012. This work was part of a larger effort to map approximately 440 miles of river in the Upper Missouri River headwaters (click for report).  The work is 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 included input and review from stakeholders associated with each of the mapped rivers.

The Ruby River Valley Conservation District and Ruby Watershed Council have a web page for the original project.
