1949 Map of North Bloomfield

About this map

San Juan Ridge and Washington Ridge dominate this landscape, reflecting the hydraulic mining legacy of the mid-20th century. The presence of the Malakoff Diggings and various Placer Diggings north of the South Yuba River illustrates the scale of earth-moving operations that once defined this region. While the primary topography was documented in 1946, later revisions show the development of Scotts Flat Reservoir and the Deer Creek Reservoir, marking the transition from mining-centric water use to larger-scale water management.
