1987 Map of Hinkson Slough

About this map

Mason Valley defines the western half of this 1980s landscape, where a complex network of waterways supports a dedicated Wildlife Management Area. The terrain transitions sharply from the wetlands of Hinkson Slough and Perk Slough to the rising elevations of the Wassuk Range in the east. Human intervention in the desert hydrology is evident through extensive irrigation works like the Nichols-Merritt Ditch and Joggles Ditch, which channel water across the valley floor. Along the northern edge, the Southern Pacific railroad corridor skirts the boundary of the Walker River Indian Reservation, marking a vital transport link through the Great Basin. The map details the intersection of the Walker River with industrial features such as a Gravel Pit, reflecting the area's mix of conservation, agriculture, and resource extraction during this era.
