We have been following the National Weather Service (NWS) forecast for both the weather and river levels. It appears that while we will have a rainy Thanksgiving weekend, we should not experience any unusual weather or flooding / high water events. The Cowlitz River at Kelso was forecast to reach flood level today but that forecast now shows the river cresting below flood stage.
The DEM duty officer will be monitoring the weather forecasts and river levels over the weekend and will send out an e-mail notification should things change. We will also post a notice on our Blog and by Twitter if the need arises. You can sign up for both of these notifications by going to our website at: http://www.co.cowlitz.wa.us/dem/
For those living along the Lewis River below Merwin Dam we have been notified that as of 10:00 AM today PacifiCorp has increased flow from the dam to 16,000 cfs. This is a low level increase and should not cause any problems to residents below the dam.
