Oregon watersheds

Oregon watersheds are large areas of land where all the water—rain, snow, and runoff—drains into a common river or stream system, eventually reaching the ocean. They include forests, mountains, valleys, and wetlands, and are vital for providing clean water, supporting wildlife, and sustaining agriculture and communities. Oregon’s diverse climate and topography create many distinct watersheds, each with unique ecological characteristics. Protecting watersheds involves managing land and water use to prevent pollution, conserve habitat, and ensure healthy water flow for ecosystems and human needs.
