Geographic Units

We have divided the Yakima Basin into geographic reaches based on tributary watersheds and mainstem reaches. While we tried to follow HUC boundaries where possible, this is a unique arrangement that is meant to match how we talk about places in the basin. ADD LINK/IFRAME FOR MAP

The links below take you to individual pages for each area, where you can find detailed information on the watersheds, streams and river reaches in each geographic unit.
