About this map

Tinemaha Reservoir dominates this high-desert landscape in the mid-1990s, serving as a critical infrastructure point for the Owens River. The map highlights the complex water management of the valley, featuring a massive Lava field to the south and the protective embankments of the reservoir itself, including the Outlet Tower and spillway. This area within the Inyo National Forest reveals a layered history of transportation and resource extraction.

Evidence of earlier industry and transit is visible in the prominent Old Railroad Grade that skirts the western edge of the reservoir. To the south, numerous natural water sources like Big Seeley Spring and Little Seeley Spr emerge near the base of the Poverty Hills. The presence of several Prospect sites and a Rock Quarry underscores the mineral interest that once drove activity around Charlie Butte and the arid expanse of Harkless Flat.
