Upper Middle Fork John Day River Intensively Monitored Watershed (IMW)


The Oregon Watershed Enhancement Board (OWEB) in conjunction with tribal entities, state and federal agencies, and private organizations has embarked on an Intensively Monitored Watershed (IMW) in the Upper Middle Fork of the John Day River.  This IMW is aimed at determining what the combined effects of different types of restoration actions are to the physical and biological functions and processes on a watershed scale.  The idea of an IMW requires a large amount of coordination from the constituents that are completing restoration and subsequent monitoring of these actions.

Project Summary

In 2007, discussions about forming the IMW study plan began and in 2008 data collection for this effectiveness monitoring at the watershed scale began.  Initial monitoring activities in the IMW were focused around Steelhead and Chinook salmon, stream temperature, riparian condition, and stream channel morphology.  In addition, socio-economic indicators were added in 2009.  The plan is to conduct this monitoring for at least 10 years to identify a clear trend in the watershed.  Results will be provided each year over the life of the project.

10-Year Final Summary Report

A Final Summary Report​ was completed in December 2017 that summarizes data collected from 2008 to 2016. This report represents 10 years of work by numerous agencies, organizations and individuals conducting restoration, research, and monitoring activities in the upper Middle Fork John Day River. Each principal investigator and their co-authors wrote a final report, which represents the culmination of their research and monitoring. The reports were compiled, along with pertinent background information, into this final Summary Report. An extensive overview of MFIMW activities, key findings, and recommendations can be found in the Executive Summary.
