The Applegate River and its intricate network of agricultural irrigation ditches define the landscape of this southwestern Oregon valley during the early 1980s. A complex system of water management is visible through the winding paths of the Laurel Hill Ditch, Watts and Topping Ditch, and Berryman Ditch, which support the lowlands of Missouri Flat. These structures highlight the region's reliance on river water for both agriculture and mining operations.
