Cedar is north of the Green… IIRC, the White used to flow into the green and was called the White as it flowed into Duwamish… but a flood changed that… here is the story… https://en.wikipedia.org/wiki/White_River_(Puyallup_River)

Flood changed it and then they filled the old channel connection to make it permanent under a state law in the late 1800s/early 1900s is my limited understanding. I'm working on a habitat restoration project in the LDW and found the history of land use in the basin particularly interesting. I'll spend a minute tomorrow to find the references/citations I used in explaining this in the report, but I'm pretty sure the best stuff is all King County, they have loads of freely available information and research about the Duwamish-Green watershed going back decades.

You referring to the black(?) river? When the gov't changed that river, it was devastating to the native tribes.

I actually talked about the Black River as part of the Duwamish system in a different comment on this Map’s thread…. It was absolutely devastating to the natives.

Historically, The White actually was the key river in the old Duwamish system.. like instead of the Green flowing into the Duwamish, the river was called the White. a flood actually changed the course of the White and pushed it into the Puyallup…

I grew up on the Cedar in Maple Valley and then got to work on the Watershed for three summers as a young woman…. The Cedar used to flow into the Black, and the Black also drained Lake Washington…. and all of it flowed into the Green/White over by SouthCenter, and it all flowed into the Duwamish….

Nice info, love it. I have deep roots here, but grew up elsewhere. But now live here. ..lol...It has close family ties and all for me. So I'm curious why that map has the cedar mapped, it could be they actually walked over there, and that's the simple answer. But I'm now curious what its historic impact truly was. I'm also curious now about this 1906 flood that was so massive it altered a river's course.
