Last week was a big week for Camp Polk Meadow Preserve. Whychus Creek was running unusually high at 375 cubic feet per second (cfs) testing our newly restored channel and all its side channels. The good news is that for the first time in years the Creek was able to use its floodplain!
The restored channel isn't as eroded and deep as the old channel was, so the water can flow over its banks and into side channels. This in turn slows the water down and causes less erosion. Though the shape of the creek and its side channels may change when we have high water flows, the creek is now moving around the meadow like it should.
To see what 375 cfs looks like, check out this video from one of the high flow days:
