About this map

The Missouri River corridor in Broadwater County is defined by a complex network of irrigation and aviation infrastructure in the mid-1980s. The landscape transitions from the southern reaches of Canyon Ferry Lake to an agricultural plain sustained by the Broadwater Canal and Montana Ditch. Central to this area is the Townsend Airport, positioned near the Rodeo Ground and a local Golf Course, reflecting the civic and recreational priorities of the era.

Local genealogy and history are anchored by the small settlement of Holker and a rural Cem located near the riverbank. The terrain is marked by numerous drainage systems flowing from the east, including Deep Creek, Cottonwood Creek, and Greyson Creek. These watercourses carve through the landscape to join the Missouri, creating a geography shaped by both natural hydrology and the early engineering of the Montana irrigation systems.
