Dam Removals: Rivers on the run

Marmot had nearly 20 times more sediment and Condit had double that of Marmot. Because it would be too expensive to dig out that material and carry it away, project managers opted for a more radical approach, colourfully described as “blow and go”, in which the dams were removed quickly, says Gordon Grant, a research hydrologist at the Forest Service's Pacific Northwest Research Station in Corvallis, Oregon.

Sandstone arches form under their own stress

Other scientists, (including sedimentologist Chris Paola of the University of Minnesota in Minneapolis, who wrote an accompanying News & Views), say the work provides an answer to the long-standing question of how such sandstone landscapes form. Gordon Grant, a research hydrologist at the US Forest Service's Pacific Northwest Research Station in Corvallis, Oregon, calls the explanation "simple, elegant, and plausible".

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.
