About this map

The Lake Helena basin serves as a critical hydrologic hub where the Missouri River meets a complex network of managed waterways. This landscape is defined by the massive Helena Valley Canal and the Helena Valley Regulating Reservoir, illustrating the intensive irrigation and water management infrastructure essential to the Helena Valley. To the north, the Helena National Forest rises above the shoreline of Hauser Lake near the Black Sandy area.
