Gunbarrel and Niwot anchor this high-plains landscape, where the legacy of early water management is visible in an intricate network of ditches and canals. The map details the sophisticated irrigation system essential to the Saint Vrain Basin, including the Table Mountain Ditch, Holland Ditch, and Boulder Feeder Canal. These waterways snake around prominent landforms like Haystack Mtn and Valmont Butte, illustrating how the natural topography was adapted for agricultural and municipal use.
