The Issue: Large, in-channel wood that helps to create and maintain healthy aquatic habitat in rivers throughout the Pacific Northwest was removed from many rivers in the past. In 2009, King County put wood back into the river to restore the Raging River watershed. To guide the county's restoration of the Raging River watershed, managers need to know the effect of restoration actions on in-stream habitat, including the occurrence and availability of cold water for fish to use as a refuge.
How USGS will help: To help King County restoration managers, the USGS will collect temperature data to characterize the thermal regime of the Raging River in a reach where wood was introduced in 2009 and in an unaltered control reach immediately upstream of it. USGS scientists will use fiber-optic distributed temperature sensing and other methods to understand groundwater-surface water interactions along the river.
