When the Skagit Floods and Diablo Turns Green

December 1st, 2017 | Posted by in Institute News

In the photo above, WSDOT contractor crews replace washed out riprap to protect and repair State Route 20 along the Skagit River east of Rockport.

WSDOT Word of the Day:

 rip·rap
/ˈriprap/
North American
noun
noun: rip-rap
1. loose stone used to form a foundation for a breakwater or other structure.

Have you noticed the washout near Cascadian Farm?

Or the unusual color of Diablo Lake?

Last week the Skagit River rose to a high of 34.69 feet, according to the U.S. Geological Survey gauge in Concrete. The highest levels of flooding since 2006, according to the National Weather Service. Flood level is 28 feet.

What was originally forecasted to be minor flooding became major flooding throughout Skagit County, causing significant property damage and road closures.

Our Water, Your Future: The Story of Climate Change and the Skagit River

What do you love about the North Cascades and the Skagit Valley?

I love the burning feeling in my legs as I hike up the switchbacks on the trails that travel through thick forests of Douglas Firs, Western Hemlocks, and cedars. The sounds of the forest bring me bliss. The birds calling in the distances, the winds rushing over tree tops, and the buzz of bees pollinating plants. Most importantly I am in awe by the abundance of water. In the spring, the North Cascades fills with raging creeks from snowmelt and from lookout points I can see snow covered peaks. I know summer is coming when Diablo Lake changes from a greyish blue to a vibrant aquamarine color.

How important is water in the North Cascades?

The North Cascades is water rich and named after all of the cascades that flow through the landscape. In the winter, snow piles up on the mountaintops; in the spring the snowpack melts, supplying water to the streams; in the summer glacier melt feeds our alpine lakes and dam reservoirs. The rainy fall then replenishes our dry summer soils and increases the flows in our rivers.

Thanks to our abundant water supply and diverse ecosystems, the North Cascades and Skagit Valley have all five native Pacific salmon species. Eagles soar through the sky, ospreys hunt, and wolverines dig deep dens in the snow. When the supply and timing of water changes in the mountains, it also changes the watershed. People, agriculture, hydroelectric production, plants, and creatures, all depend on reliable water sources to thrive.
