1962 Map of Wallace

About this map

The Mokelumne River corridor undergoes a significant transformation on this early 1960s survey, dominated by the newly developing Camanche Reservoir. Blue hatching indicates the extensive areas slated for submersion by the reservoir at elevation 236, a change that fundamentally altered the geography of local settlements like Camanche and Lancha Plana. The landscape is heavily marked by industrial history, featuring numerous Dredge Tailings, Quarries, and Tailings piles that speak to decades of resource extraction along the riverbanks.
