The Sacramento-San Joaquin River Delta of California - covering the right half of the map.

• The Sacramento River flows into the delta from the north and the San Joaquin River from the south. The San Joaquin and Sacramento rivers meet just west of Antioch and their confluence continues westward into Suisun Bay and then the Carquinez Strait (both on left of map).
• The Mokelumne River enters from the east, flows northwest from Lodi, picks up several tributaries including the Cosumnes River, then turns south, meandering among several delta sloughs and waterways, ultimately flowing into the San Joaquin River in the center of the delta, northeast of Antioch.

• The "lake-like" body of water near the bottom of the image is Clifton Court Forebay, where pumps lift water to be sent southward in the California Water Project canal.
• Several other open areas in the right half of the image are "islands," many of which have elevations well below sea level. Waterways (in blue) are clearly visible, as are fields and croplands (which appear as patchwork), and urban areas (especially Stockton).
