Fernhill Natural Treatment Wetlands

The amount and type of algae in the Tualatin River affect the river’s water quality and ecological health, as well as its value as a recreational resource. As a relatively new source of summertime flow to the upper Tualatin River, discharges from the Fernhill Natural Treatment System (NTS) have the potential to enhance or degrade downstream water quality. Discharges of low nutrient...

Synthesizing the State of Science of Coldwater Refuges in the Willamette River Basin

Many regulatory, management, and conservation organizations are interested in protecting and increasing coldwater refuges and thermal diversity for Chinook salmon, steelhead, and other natives fishes in the Willamette River basin. This study synthesizes current and emerging science related to coldwater refuges and thermal diversity. It is also develops conceptual frameworks for understanding...

Controls on Habitat for Native Lampreys in the Umpqua River Basin

Native lampreys are culturally significant fishes for tribal communities in Oregon. As such, the USGS has begun working with the Cow Creek Band of Umpqua Tribe of Indians to study changes that may be affecting habitat for native Pacific and western brook lampreys in the Umpqua River basin.

Willamette Instream Flows

When streamflow fluctuates in the Willamette River so does the amount of available rearing habitat used by Threatened Upper Willamette River spring Chinook salmon and winter steelhead trout. The USGS investigates how flow conditions and dam operations affect rearing habitat availability so that flow managers can maintain suitable flows for these species.

Oregon Water Use Program

With the ever-increasing rate of utilization of and competition for water (particularly during periods of drought) accurate, current water-use information is of considerable value. This is particularly so in determining future water availability in hydrologically critical areas and for making sound resource-management decisions. For the Oregon Water Science Center, a viable water-use data-...
