1925 Map of Helm

USGS Topo · Published 1925

About this map

Fresno Slough dominates this central California landscape, reflecting a period of significant hydraulic engineering and agricultural development. The map illustrates a complex water management system characterized by the Stinson Canal, a Diversion Dam, and the Main Bypass, which together transformed the arid valley floor into productive farmland. Settled life centers on the rail-stop at Helm, where the Southern Pacific railroad line intersects with the local road network. The presence of the New Hope School and the settlement of Nares further south suggest the growing community of the mid-1920s. The landscape is defined by the rigid geometry of the public land survey system, with roads like Manning Avenue and Floral Avenue following section lines across the valley, creating a stark contrast with the meandering path of the slough.
