1973 Map of Lake Fork

About this map

Long Valley in central Idaho is defined here by its complex irrigation network and the transition from fertile valley floor to the foothills of Timber Ridge. The settlement of Lake Fork sits at a geographic crossroads near where the Old Union Pacific RR Grade once tracked through the valley. This 1973 survey details an economy reliant on water management, featuring the Irrigation District Canal and numerous siphons, flumes, and storage bins that support the surrounding ranchlands. The southern portion of the map is dominated by the northern reaches of Cascade Reservoir, which significantly altered the local drainage of Lake Fork and Mud Creek. Genealogists will find the Finn Cem and Spink Cem particularly noteworthy, along with the smaller community of Norwood and the landing strip that underscores the region's connectivity.
