About this map

Mizpah Creek and Forty Creek weave through this section of Custer County, shaping a landscape defined by an extensive system of small-scale water management. The terrain is marked by numerous localized reservoirs, including the Robinson Number 4 Dam, Robinson Number 6 Dam, and Balsam Number 1 Dam, which indicate the critical importance of water storage for ranching or land use in this part of Montana. These features, along with the Todd Number 1 Dam, suggest a highly managed drainage network designed to capture runoff from seasonal coulees.

Transportation is primarily represented by the prominent Mizpah Rd, which follows the general path of the creek valley. The map also records several named drainages such as Timothy Creek, Bridge Creek, and Hercules Creek, providing a detailed look at the hydrology north of Dawson Coulee. For the local historian or researcher, these family-named landmarks and specific dam locations offer a clear record of twentieth-century land development in the high plains.
