Grande Ronde Valley agriculture and the foothills of the Whitman National Forest define this area of Union County. The settlement of Cove serves as the central hub, situated where the valley floor meets the rising terrain of the Grande Ronde Ridge. This landscape is deeply shaped by water management, featuring an intricate network of irrigation and drainage including the Catherine Cr Highline Canal, Phys Slough, and several upland water bodies like Elmers Reservoir 1.
