About this map

Boulder Reservoir and its surrounding water network dominate the landscape of this 1967 survey, reflecting the complex irrigation and storage systems of the Front Range. The map details the transition from the agricultural heritage of Niwot and Valmont to the suburban and industrial growth of northeast Boulder. A network of ditches, including the South Boulder Canyon Ditch and the Boulder and Whiterock Ditch, feeds into various reservoirs such as Leggett Reservoir and Valmont Reservoir.

Cultural and institutional development is evident in the presence of several educational and community sites, such as Niwot Sch, Arapahoe Sch, and the Boulder Municipal Airport. Distinctive geological features like Haystack Mountain and Valmont Butte provide clear landmarks among the shifting land use, which includes early gravel and clay extraction at various Gravel Pit locations and the heavy rail influence of the Colorado and Southern and Union Pacific lines.
