The Columbia River has historically been a major source of economic activity for the Pacific Northwest, and is one of the more heavily modified rivers in the United States today. Understanding human and climate-induced changes in its hydrologic properties is, therefore, a topic of considerable ...
A network of 32 drought sensitive tree-ring chronologies is used to reconstruct mean water year flow on the Columbia River at The Dalles, Oregon, since 1750. The reconstruction explains 30 percent of the variability in mean water year (October to September) flow, with a large portion of ...
The Pomona Member of the Saddle Mountains Basalt (Columbia River Basalt Group) occurs as an intracanyon flow greater than 75m (250ft) thick along the S side of the Columbia River Gorge between Mitchell Point and Shellrock Mountain, Oregon. Best exposures are at Mitchell Point, where this flo...
However, much larger eruptions in the geologic past, with eruption rates on the order of 106 m3 s− 1, produced voluminous sheet-like lava flows (e.g., the Columbia River Basalts, northwestern U.S.) that covered tens of thousands of square kilometers and formed extensive volcanic plateaus...
A flow-duration curve represents the annual flow-frequency characteristics of rivers by depicting the cumulative frequencies for average ranked flows in a river. Generally the process requires the empirical estimation of the mean flow at each of 365 ranks. A model requiring only five parameters is ...

When combined with the outflows from the Kootenay River, Columbia River levels at Birchbank are expected to decrease by 0.57 metres (1.9 feet). Please make safety your top priority when planning activities near the Columbia River.For up-to-date reservoir elevation and river flow information, ...
