After nearly three weeks, the Columbia River is expected to fall below flood stage Tuesday.
The National Weather Service announced the river was in a flood watch on March 16, as it neared the 16-foot minor flood stage. The Columbia River sat at 16.4 feet on Monday, according to the weather service, down from 16.8 feet on Sunday. The river crested at 17.6 feet at 10 p.m. on March 30.
“With the bigger rivers, like the Columbia, when it gets above flood stage, it takes long for the river for the rise, it takes longer for the river to fall,” said Laurel McCoy, a meteorologist from the National Weather Service in Portland. “Because all that water is coming from farther away, from snow melt in Eastern Washington and Canada, we had to wait for it all to come down. Once we started getting less snow melt and less water from the big dams up there, it’s allowed the Columbia to come back down a bit.”
The lack of rain in the last week has helped, too, McCoy said.
The weather service’s forecast calls for the Columbia to drop below the flood stage sometime early Tuesday. It will continue to drop for the rest of the week, and the weather service is forecasting the Columbia should be around 14.7 feet by Friday. It will still have a bit to go before it’s back down to normal, though.
