2010 Map of Lake Walcott West

About this map

Lake Walcott dominates this 2010 landscape, representing a critical intersection of hydrology and early 20th-century engineering in southern Idaho. The Snake River is harnessed here at the Minidoka Dam, a cornerstone of regional irrigation that feeds the complex network of the Main North Side Canal and Main South Side Canal. These waterways define the boundary between the reservoir's expansive reach and the structured agricultural grid to the north and south. The map documents a sparsely populated but highly organized territory, characterized by long, straight thoroughfares like Main Line Ranch Rd and River Ranch Rd that service the surrounding plains. To the northeast, the settlement of Hawley sits along the roadway system, while North Refuge Rd leads toward the protected wildlife habitats along the lake's northern shore. The survey provides a clear view of how the E Minidoka Dm infrastructure continues to manage the vital water resources of the Snake River Plain.
