Haystack Mountain and Gun Barrel Hill rise above a landscape defined by an intricate network of irrigation systems and modern development north of Boulder. This 2013 survey details the complex water management infrastructure essential to the region, including the Boulder Feeder Canal, Holland Ditch, and the massive Boulder Reservoir. These waterways support the agriculture and communities of Niwot and Gunbarrel, while industry and infrastructure are represented by the Table Mountain Antenna Field Sites and the City of Boulder Wastewater Treatment Facility.
