Data from Usk, the nearest gaging station on the Skeena River, demonstrate that the stage was high enough to form the flood scars for only 24 to 36 hours. Most of the flood scars had to form in less than 24 hours. Field observations suggest that the time of flood-scar formation was ...

Results suggest that water levels in Portland at low river discharge are up to 0.5-1.0m lower than in the past. However, historical water levels during a flood scenario based on the 1880 spring freshet are similar to modern water levels. Since tidal range in the modern scenario is ...
This paper presents a novel approach for assessing flood risks in the Columbia River Basin. Colder Associates Inc. (Golder) conducted a study to assist our client in making decisions regarding flood insurance for a site in St. Helens, OR, near River Kilometer 140.8 of the Columbia River. A ...
The Miocene Columbia River Basalt Group (CRBG) is the youngest and best preserved continental flood basalt province on Earth, linked in space and time with a compositionally diverse succession of volcanic rocks that partially record the apparent emergence and passage of the Yellowstone plume head thro...

Near the Pleistocene Termination, a glacier-dammed lake in central British Columbia suddenly drained to the south along the Fraser River valley. Floodwater travelled 330 km down the valley to Hope, British Columbia, and from there to the west into the Salish Sea near Vancouver. The flood was...
The USA and Canada have entered negotiations to modernize the Columbia River Treaty, signed in 1961. Key priorities are balancing flood risk and hydropower production, and improving aquatic ecosystem function while incorporating projected effects of climate change. In support of the US effort, Chegwid...
