Welcome

Thanks for visiting the Upper White River Channel Migration Zone (CMZ) Study website. Starting in 2019, Pierce County will conduct a CMZ Study along the Upper White River from Greenwater to upstream of Crystal River Ranch and Crystal Village along Highway 410.

Our website will be fully live in April. We’ll have information about the study, how it will be conducted and how you can provide important feedback to the county on the study.
