About this map

Bacon Island and the surrounding Sacramento-San Joaquin Delta landscape are defined by an intricate network of man-made waterways and reclaimed tracts in this late 1970s survey. The map details the complex hydraulic engineering of the region, where the Mokelumne Aqueduct and numerous siphons intersect with natural channels like the Old River and Middle River. Settlements such as Orwood and Bixler sit along the Atchison Topeka and Santa Fe railroad, illustrating the vital transport links that served these agricultural islands.

Evidence of the local river-based economy is visible in features like the Woodward Island Ferry and the Rindge Sch, positioned among the sprawling tracts like the Palm Tract and Holland Tract. The inclusion of the Contra Costa Co Boys Ranch and the Sewage Disposal Ponds near the Byron Tract provides a look at the institutional and infrastructure footprint on these low-lying lands, which the margin notes as a subsidence area.
