Cascade-Siskiyou National Monument anchors this southern Oregon landscape, where the high-altitude hydrology of the Cascades is heavily managed through a network of reservoirs and canals. The map showcases significant water infrastructure, including the large Howard Prairie Lake and Hyatt Reservoir, which are linked by the Howard Prairie Canal. This system of reservoirs, which also includes Little Hyatt Reservoir and Keene Cr Reservoir, illustrates the mid-century engineering used to divert and store water across the rugged Jackson County terrain.
