The Snake River winds across the northern landscape of this region, feeding an intricate network of waterways essential to the local valley economy. Irrigation is the dominant theme of the terrain, visible through the density of man-made channels like the Parks Lewisville Canal, Burgess Canal, and Garfield Ucon Canal. These systems support the established communities of Rigby, Annis, and Garfield, where the grid of county roads follows the linear path of the water.
