They dumped 6,100 whole trees across an Oregon floodplain, filled parts of an old creek channel with soil, and let the water choose its own path.
At first, Rimrock Ranch on Whychus Creek looked like it was being destroyed. But this was one of Oregon’s most ambitious river-restoration projects.
For decades, Whychus Creek had been straightened, confined by berms, and separated from its natural floodplain. The result was a fast, simplified channel with fewer pools, side channels, wetland areas, and safe places for fish and wildlife.
Instead of building one new “perfect” creek channel, restoration crews used a process called Stage Zero restoration. They reshaped the valley floor, moved around 70,000 cubic yards of earth and rock, planted 96,500 native plants, and spread thousands of whole trees—with branches and root wads—across more than 59 acres.
Then they released the creek.
The wood slows water, redirects current, creates pools, traps sediment, provides shelter for fish, and helps the river build a more complex habitat over time. Almost immediately, the number of pools in the restoration area increased from 35 to 119.
But the biggest question takes longer to answer: can this restored floodplain help salmon and steelhead recover?
In this video, we explore:
• Why rivers were straightened in the first place
• Why fallen trees are essential habitat instead of “river clutter”
• How Stage Zero restoration works
• Why the project looked destructive before it became restorative
• How floodplains store water like a sponge
• What the early results mean for fish, wildlife, groundwater, and vegetation
• Why scientists are still monitoring the creek years after construction
A healthy river is not always one clean blue line on a map. Sometimes it is a shifting, messy network of pools, side channels, logs, wetlands, plants, sediment, and moving water.
