Upper Klamath Lake dominates this 2011 survey, showing a landscape defined by water management and mountainous terrain. The eastern shoreline is marked by engineering features like the Caledonia Dike and Cross Dike, which separate the primary waters of Howard Bay from reclaimed areas and drainage networks including the Caledonia Canal. These structures reflect a long history of altering the lakeshore for agriculture and settlement, most notably seen at the Running Y Ranch development near the southern edge of the quadrangle.
