Jeffrey Reservoir dominates the eastern portion of this Nebraska landscape, a critical component of the regional water management system fed by the Tri-County Supply Canal. The map illustrates the transition from the braided hydrology of the Platte River valley in the north, where Chester Island and Brady Island are located, into the deeply dissected canyonlands to the south. This terrain is marked by a series of prominent drainages including Snell Canyon, Conroy Canyon, and Jeffrey Canyon.
