Little Porcupine Creek meanders through this Valley County landscape, defining a drainage system that includes Johnson Coulee and Oswego Creek. During this early 1970s survey, the area reflects a sparsely populated ranching or agricultural environment characterized by essential water infrastructure and storage facilities. Smaller water bodies like Horgan Reservoir and the namesake Dubbe Reservoir are critical focal points in an otherwise arid expanse, joined by numerous named Spring and Springs locations.
