Range of bull trout in Oregon's McKenzie River indicates improved river health

By September, many western rivers that rely on snowmelt runoff are reduced to a trickle. But groundwater keeps systems like the McKenzie River robust with water temperatures ranging around 48 to 53 degrees. The temperature of the cold water springs in the McKenzie range between 39 and 44 degrees.

The Ambitious Restoration of An Undammed River

“The Elwha is a very important system to watch,” says Gordon Grant, a hydrologist at the Pacific Northwest Research Station in Corvallis, Oregon. “It tells us what to expect from a massive societal investment in river restoration.”

Satellites tracking changes in water supplies across the U.S.

GRACE is providing “the first real, continental scale measurements of changes in water, and that’s new,” said Gordon Grant, a research hydrologist with the USDA Forest Service’s Pacific Northwest Research Station in Corvallis, Oregon.


'Watering the forest for the trees' emerging as priority for forest management

“Our work emphasizes how forests primarily need and consume water, and so managing forest health requires thinking about how much water is available for forests, how forests use that water, and how management strategies can mitigate increasing drought stress,” said station research hydrologist Gordon Grant, who led the analysis.

Climate Change impact on stream flow differs according to location

A new analysis of river basins in the western United States suggests that climate change will have the greatest impact on summer stream flows in those waterways that might seem less vulnerable – the large, snow-fed rivers that originate in the high Cascades and other mountain ranges.
