1965 Map of Beckwith Arm

USGS Topo · Published 1982

About this map

Falcon Reservoir dominates this landscape along the international border between the United States and Mexico. The shoreline of the Beckwith Arm is characterized by intricate inlets and fingers of water where the Arroyo Blanca and Arroyo Calaveras reach the reservoir. This mid-century survey captures the region's energy infrastructure, specifically the Lopeño Gas Field with its network of pipelines, gas wells, and a Pumping Sta. Leisure and utility coexist along the water's edge at the Marina and Trailer Camp, which is supported by a nearby Boat Ramp and a small Landing Strip. The map also includes specific legal notations regarding flowage easements and land ownership between the 307 and 314-foot elevations, reflecting the managed nature of the reservoir's margins.
