About this map

The Missouri River corridor in Broadwater County is defined by a complex network of agricultural irrigation and ranching life in the mid-1980s. The landscape transitions from the waters of Canyon Ferry Lake in the northwest to the rugged drainage basins of Deep Creek and Greyson Creek. The prevalence of the Montana Ditch and numerous unnamed canals underscores the vital role of water management in this high-plains environment.
