The North Umpqua River and its complex hydroelectric infrastructure define this section of the Cascade Range, characterized by the 21st-century management of the Umpqua National Forest. The map documents a sophisticated network of water diversion, including the Lemolo Number 2 Canal and Clearwater Canal Number 2, which feed into facilities like Lemolo Forebay Number Two and Clearwater Number Two Forebay. These systems are anchored by the Soda Springs Reservoir and Toketee Lake, showing how the rugged terrain around Flatiron Point and Camel Hump has been adapted for power generation.
