USGS Scientific Investigations Report 2010–5016 Development of an Environmental Flow Framework for the McKenzie River Basin, Oregon

Table 6. Streamflow-gaging stations or streamflow points of the study reach, McKenzie River basin, Oregon.

[River mile from the nearest downstream confluence. For reaches without a streamflow-gaging station, a river mile at a midpoint in the reach was selected. Data period: A water year is from October 1 to September 30. Abbreviations: mi², square miles; na, no streamflow gage in this reach]
