1962 Map of Carter Lake Reservoir

About this map

Carter Lake Reservoir dominates this 1962 landscape, serving as a focal point for the complex irrigation and power infrastructure of the Colorado Front Range. The map illustrates a sophisticated system of water management, featuring the St Vrain Supply Canal, Handy Supply Ditch, and Penstocks that connect to the Flatiron Powerplant. This industrial footprint is integrated into the terrain of the foothills, where Flatiron Mountain and Indian Mountain rise above the surrounding valleys. Numerous small reservoirs, including Lonetree Reservoir and Highland No 2 Reservoir, are scattered throughout the quadrangle, reflecting the area's agricultural dependency. Evidence of local industry is also visible in the recurring Quarry and Quarries labels near Chimney Hollow, while the Little Thompson River carves its path across the southern boundary between Larimer and Boulder counties.
