About this map

Lemolo Lake serves as the central hub of this mountain landscape within the Umpqua National Forest, where the hydrology of the N Umpqua River is managed for power generation. The map documents the industrial infrastructure supporting the region, including the Lemolo Canal Number 1, the Lemolo 1 Penstock, and the Lemolo Plant Rd. This specialized network of canals and pipelines redirects water across high-elevation terrain to harness the steep drops of the Cascades, most notably near the dramatic Lemolo Falls.

Beyond the reservoir, the topography is defined by prominent volcanic features and evocative local place names. Peaks such as Kelsay Mtn and Elephant Mtn overlook a complex system of Forest Service roads. To the west, the foreboding Dread and Terror Ridge and Watson Ridge wall off the river valley, while to the south, the landscape opens into Pumice Flat and the headwaters of the Clearwater River near Mowich Park.
