About this map

Ackley Lake serves as the central focal point for this Judith Basin landscape, where early 1970s irrigation infrastructure is clearly visible. The map details the intricate water management system of the era, including the Ackley Lake Feeder Canal, Ackley Lake Outlet Canal, and the Murray Ditch, which redirect water from the Judith River to support local agriculture. This network reveals the systematic effort to manage the high plains terrain and its seasonal springs.

To the north, the small settlement of Hobson sits near the river, while the site of Philbrook and the nearby Philbrook Cem offer important points of reference for genealogists and local historians. The surrounding land is marked by significant topographical features such as Hauck Coulee and Big Coulee, punctuated by several gravel pits and numerous isolated springs that define the rural economy and hydrology of the region.
