1967 Map of Goshawk Dam

About this map

Goshawk Dam and its neighboring reservoirs, Turkey Dam, Swan Dam, and Ostrich Dam, anchor the southern end of this high-altitude landscape in the late 1960s. These water management structures feed into The Poso, illustrating the critical role of irrigation engineering in the San Luis Valley. To the north and east, the terrain transitions into a more structured agricultural grid defined by an extensive water delivery system. Significant irrigation infrastructure, including the Romero Ditch, Mogote Ditch, and Bountiful Lateral, highlights the organized effort to divert water from natural sources like La Jara Arroyo to the surrounding ranch lands. This 1967 field-checked survey reveals a rugged interior crossed by a solitary Jeep Trail, connecting the remote western elevations near Capulin with the developing valleys to the east.
