About this map

Wheatgrass Bench rises above the Arbon Valley floor, defining a landscape shaped by a complex network of water management features in this modern Idaho survey. The northern edge of the map follows the periphery of the American Falls Reservoir, where the settlement of Bannock sits along the road and rail corridor. Moving south, the terrain transitions from the managed agricultural grids of the valley to the dissected uplands of Compressor Station Bench and the southern hills.

Water infrastructure is a primary focus, detailing the flow of the Bannock Canal, Owl Canal, and Taghee Canal through the basin. These systems, alongside features like the Big Siphon Wasteway and Bannock Drain, illustrate the intricate irrigation necessary for local agriculture. To the southwest, the terrain becomes more varied, marked by Blind Spring and Blind Spring Cr, providing a clear view of how the natural hydrology meets the man-made canals in Power County.
