@mappedearth: The Northwest's River Pulse: Every River in Oregon and Washington Oregon and Washington carry about 23 times more water at their winter peak than at the end of summer. Every thread here is a real river, drawn only by its own flow and rising and falling with the water measured in it every day since January 2025. The Pacific rains swell the whole network through December; by the end of the long dry summer it runs at its thinnest. The cool colors are cold snowmelt streams high in the Cascades, the warm ones the lowland Columbia carrying the season's heat down to the sea. Discharge: GloFAS (Copernicus, ECMWF). Rivers: HydroRIVERS. Water temperature: DynQual. #pacificnorthwest #oregon #washington #columbiariver #rivers
