1903 Map of Cuyamaca

About this map

Capitan Grande Indian Reservation dominates the central landscape of this inland San Diego County survey, flanked by the drainage of the San Diego River and a significant irrigation system including a long Flume and several tunnels such as the Cape Horn Tunnel and Los Coches Tunnel. The map documents a pivotal era of water management and transit, showing the Cuyamaca Reservoir in the north and the early stages of the San Diego Cuyamaca and Eastern R.R. connecting Lakeside and Foster. Further south, the map traces the international Boundary Line with Mexico near Tecate, while interior valleys are dotted with small ranching hubs and outposts like Honey Springs Ranch and Pine Valley Station. The distribution of resources is evident through the placement of Barrett Dam and Morena Dam, reflecting the region's early 20th-century focus on securing water for coastal growth.
