1962 Map of Carter Lake Reservoir

About this map

The Carter Lake Reservoir dominates this Colorado landscape, acting as a central hub for a complex network of water management features in the early 1960s. The map illustrates an intricate system of industrial utility, featuring the Flatiron Powerplant, several pressure tunnels, and a Spillway connecting to the Flatiron Reservoir. This infrastructure supported the movement of water across the terrain of Flatiron Mountain and through the distinct depressions of Chimney Hollow and Meadow Hollow. Along the eastern plains, a series of smaller catchment areas like Hertha Reservoir, Foster Reservoir, and Wilson Reservoir reflect the agricultural engineering of the period. Evidence of local industry is visible through numerous quarries scattered across the ridgeline, while the southern portion of the sheet traces the course of the Little Thompson River as it crosses the boundary between Larimer and Boulder counties near Dowe Pass.
