Lewisville and the agricultural lands of Polk County define this 2014 survey, where the valley floor is shaped by the Little Luckiamute River and its larger counterpart, the Luckiamute River. The landscape is a patchwork of family-named water resources, including the Oberg Reservoir, McCrae Reservoir, and Hamilton Reservoir, illustrating the intensive water management required for the region's farms and orchards. In the northern reaches, Gilliam Swale and Fishback Hill provide topographic variety against the steady rhythm of the township and range grid.
