Lewisville and Airlie anchor the southern portion of this landscape, where agricultural tradition meets the winding waterways of Polk County. The terrain is defined by the convergence of the Luckiamute River and the Little Luckiamute River, a hydrological system that supported numerous small reservoirs such as McGuire Reservoir, Ratzlaff Reservoir, and Buchanan Reservoir. These water sources, combined with the sheltered topography of Cooper Hollow and Gilliam Swale, illustrate the region’s long-standing reliance on irrigation and local water management for its valley farms.
