The Snake River meanders through this portion of Jefferson County, defining a landscape dominated by a complex network of man-made irrigation channels and natural waterways. Centered on the agricultural hub of Lewisville, the map reveals how the local economy relies on gravity-fed water systems like the Long Island Canal, Missionary Canal, and the Parks-Lewisville Canal. These waterways crisscross the terrain between the Snake River Valley and the prominent Lewisville Knolls, which rise above the surrounding flats.
