1964 Map of Threemile Reservoir

USGS Topo · Published 1967

About this map

The Fort Belknap Indian Reservation boundary defines the northern portion of this 1964 landscape, where the meandering path of the Milk River created a complex system of oxbows and natural irrigation. To support agriculture in this arid region of Blaine County, an extensive network of man-made waterways was developed, including the Milk River Canal A, North Main Canal A, and Main Canal A. These canals illustrate the mid-century infrastructure required to divert river water across the plains.
