2014 Map of Lake Helena

About this map

Lake Helena and the surrounding basin of Lewis and Clark County are defined by a complex network of irrigation and water management, including the Helena Valley Canal and the Helena Valley Reservoir. This landscape represents a modern Montana intersection of agricultural heritage and suburban growth, where residential developments like Helena Valley Southeast and Helena Valley Northeast spread across the valley floor. The hydrology is central to the area's character, with Prickly Pear Cr and Tenmile Cr feeding into the lake, while the northern reaches of the map show the waters of Hauser Lake behind the dam. Local history remains visible through features such as the Hardgrove & Merritt Cem, which sits near the foot of Emerald Ridge. Notable terrain landmarks like Sleeping Giant View and Mountain Meadows overlook the increasingly structured grid of roads and waterworks.
