1999 Map of Owens Reservoir

About this map

Owens Reservoir and Mariposa Reservoir anchor this landscape along the Merced and Mariposa County line, reflecting a region managed for water and mineral resources. The survey records a working landscape where industrial history is written into the terrain, most notably through Dredge Tailings and several Quarries that follow the creek beds. Local family history and early settlement patterns are visible at the Pate Cem and namesake holdings like Chase Ranch and Cunningham Ranch. The topography is defined by the drainage systems of Owens Creek and Mariposa Creek, which have been transformed by engineering to support the surrounding valley. This late-twentieth-century update captures the area after the major reservoirs were established but before significant modern development, preserving the footprint of the Hills Mine and the rural road network including Waltz Road and Whiterock Road.
