The Grande Ronde Valley serves as the foundation for this agricultural landscape in northeast Oregon. The small settlements of Imbler and Alicel anchor a network of rural roads, many bearing the names of early family landholdings such as Speckhart Rd, McDonald Ln, and Wallsinger Rd. This 2017 survey reveals the extensive water management systems essential to the valley, featuring the Grande Ronde River, the State Ditch, and several specialized reservoirs including the Bill Howell Reservoir and Arnoldus Loop Reservoir.
