[[File:ISH WC SuttersFort3.jpg|thumb|John Sutter plaque at Sutter's Fort]]

Sutter's Fort is located on level ground at an elevation of approximately {{convert|20|ft|m}} above mean sea datum.<ref>[[U.S. Geological Survey]], ''Sacramento East Quadrangle, 1967, photorevised 1980''</ref> The slope elevation decreases northward toward the American River and westward toward the [[Sacramento River]]. Slope elevation gradually increases to the south and east, away from the rivers. All surface drainage flows toward the Sacramento River. Groundwater in the vicinity flows south-southwest toward the [[Sacramento Delta]]. However, after peak rainfall, the Sacramento River swells and the [[groundwater flow]] can actually reverse away from the river.<ref>''[[Phase I Environmental Site Assessment]], 2617 K Street, Sacramento, California'', Earth Metrics Inc.
