The Sacramento River was named after Sacramento, California.
 The river drains about 26,500 square miles (69,000 km2) in 19 California counties, mostly within the fertile agricultural region bounded by the Coast Ranges and Sierra Nevada known as the Sacramento Valley, but also extending as far as the volcanic plateaus of Northeastern California
 Many Sacramento River fish species are similar to those in the SnakeColumbia River systems; geologic evidence indicates that the two were connected by a series of wetlands and channels about 4-5 million years ago
