Expanding our knowledge of Willamette River fish habitat

Release Date:

USGS scientists are providing important information about off-channel features of the Willamette River, which provide habitat for many fish species including salmonids. This information will fill gaps in the data needed to effectively manage the Willamette River system.

This study was initiated in response to the unusu­ally warm, dry weather and resulting low streamflows that occurred in the Pacific Northwest in 2015 and the need for flow managers to understand the effects of streamflow on water-quality conditions in off-channel features of the Willamette River. The field surveys conducted in this study provided extensive water-temperature and dissolved-oxygen datasets that were previously not available, and these new datasets can help inform management decisions for the Willamette River system. A report describing this study can be obtained from the link below.
