1950 Map of Trinity Lake

About this map

Minersville and its surrounding mountain canyons are depicted here during a pivotal transition as the Trinity Lake reservoir began to reshape the landscape. This 1950 field-checked survey preserves the locations of communities and infrastructure before they were impacted by rising waters, including Old Minersville (Site) and Sebastopol (Site). The map reveals an economy built on timber and gold, evidenced by the Covington Mill, a Quartz Mill, and numerous workings like the Globe Mine and Kelly Mine. In the southern reaches, the Lewiston Reservoir is already visible, while the rugged interior is marked by historic resource management features like the Coffee Ditch (Aband) and Minersville Ditch (Abandoned). Family and community history is anchored by landmarks such as the Ridgeville Church, Ridgeville Cemetery, and the Cedar Stock Farm located near the Stuart Fork of the Trinity River.
