A stormy February doubled the Mount Hood snowpack from five feet to ten – a relief for northern Oregon, which has been unseasonably dry. Hydrologists have told me about dramatic recoveries, but this is the first time I’ve witnessed it.
I recently joined Julie Koeberle, one of our hydrologists with USDA’s Natural Resources Conservation Service, to collect data that would be released in the March forecast from the agency’s National Water and Climate Center.
We snow-shoed out to the site and weighed the snow, and a local reporter tagged along to see how it’s done. Weighing snow allows surveyors to calculate the snow-water equivalent, in other words, how much water is in the snow. Light, fluffy snow contains less than dense, packed snow.
