Which California location marks the southern extent of the white sturgeon's historical range?

Answer

San Joaquin-Sacramento River Delta

The historical geographical distribution of the white sturgeon covered extensive Pacific coast drainages, spanning a massive latitudinal range within North America. This range commenced in the north, extending down from the Bering River in Alaska. The southernmost boundary of this historical habitation area was documented as reaching down to the San Joaquin-Sacramento River Delta located in California. Additionally, the species' former range also included parts of the upper Gulf of California, showing a broad distribution along the Pacific coastal regions.
