About this map

Lake Helena dominates this landscape, serving as a focal point for a complex network of irrigation and natural drainage in the northern reaches of the valley. The expansive Helena Valley Canal and the Helena Regulating Reservoir infrastructure illustrate the engineered water management essential to the region's agricultural and residential development. To the south, the census-designated areas of Helena Valley Northeast and Helena Valley Southeast show a transition from open terrain to more structured suburban settlements, including the neighborhood at Stansfield.

Tracing the movement of water, the Prickly Pear Creek and Tenmile Creek flow toward the lake, while the eastern edge of the map captures the Missouri River as it enters Hauser Lake. Along the northeastern ridges, the Helena National Forest boundary meets rugged terrain near Favorite Gulch. Local history researchers will find the Hardgrove and Merritt Cem south of the lake, a small but significant site for genealogical study.
