The town of Bonanza sits at the heart of this Klamath County landscape, positioned where the Lost River winds through a basin defined by agricultural history and complex water management. The intersection of Yonna Valley, Poe Valley, and Langell Valley creates a unique geographic hub, where irrigation features like the Yonna Ditch and Warden Reservoir illustrate the long-term engineering required to sustain local ranching and farming.
