Amity anchors the northern portion of this Yamhill and Polk County landscape, situated where the Amity Hills meet the fertile valley floor. The map documents a highly managed hydrological environment, defined by numerous named irrigation and storage sites such as Phil Olson Reservoir, Rohde Reservoir, and the Martin Brothers Flashbound Reservoir. This network of water management supports the agricultural character of the region, including operations near the Vineyard Airport.
