During last month’s heat wave, snow rapidly gave way high up on the northeast slopes of Mount Hood.
The triple-digit temperatures melted high-up snow pack and sent it rushing down the mountain, flooding roads and causing campsite evacuations.
The effects the event had on Oregon’s drought are likely more lasting. That high-elevation snow would typically trickle down the mountain throughout the season, nourishing local ecosystems.
“That’s a water supply that would enhance or continue stream flows throughout the summer months,” says Scott Oviatt, snow supervisor for Natural Resources Conservation Service Oregon. “With that rapid melt-out and washing down stream, it makes it unavailable for future use, so it is a concern.”
But even before the rapid melt on Mount Hood, Oregon’s water reserves were disconcertingly low. By that point, the area’s snow pack had already melted out a few weeks early, and the whole region had been experiencing record-low precipitation for months.
“We as a society are facing challenging times responding to these widely variable conditions, plus the lack of surface water,” says Oviatt. “Surface water is what makes our area thrive.”
