1985 Map of Derby Dam

About this map

The Truckee River carves a critical corridor between the Pah Rah Range and the Virginia Range in this mid-1980s topographical survey. This canyon serves as a major infrastructure artery, carrying the Southern Pacific railroad and Interstate 80 alongside historical transportation routes. Significant among these are the Emigrant Trail and California Trail, marking the enduring path of westward migration through Nevada. At the center of the map, Derby Dam diverts water into the Truckee Canal, an early 20th-century engineering feat of the Newlands Project. Industrial activity is evident at the Celatom Mine and several Tailings Ponds, while small settlements like Clark and Thisbe occupy the narrow valley floor near the Washoe and Storey County line.
