2023 Map of Ninemile Slough

About this map

Harney Valley is defined by an intricate network of wetlands and seasonal watercourses, most notably the meandering Ninemile Slough. This modern survey illustrates the persistent drainage patterns of this high-desert basin, where human presence is marked by a grid of rural lanes and remote landing facilities like Hooks Strip. The map detail follows the progression of agricultural development through family-named roads such as Hutchenson Ln and Ruhl Rd, which navigate the flat, saturated terrain between the various township and range boundaries. The landscape is characterized by its high water table, with numerous unnamed marshy pockets and channels that suggest a region deeply influenced by seasonal runoff and basin-floor hydrology. This topographic study serves as a clear record of the modern road network, including Crane Blvd and the Lawen-Harney Rd, as they interface with the natural flow of the slough system.
