Most valley lowlands are prone to flooding, especially in the old [[Tulare Lake]], [[Buena Vista Lake]], and [[Kern Lake (Kern County)|Kern Lake]] rivers. The [[Kings River (California)|Kings]], [[Kaweah River|Kaweah]], [[Tule River|Tule]] and [[Kern River|Kern]] rivers originally flowed into these seasonal lakes, which would expand each spring to flood large parts of the southern San Joaquin Valley. Farms, towns, and infrastructure in these lakebeds are protected with levee systems, while the risk of floods damaging properties increased greatly.

The [[Great Flood of 1862#Central Valley|Great Flood of 1862]] was the valley's worst flood in recorded history, flooding most of the valley and putting some places as much as {{convert|20|ft}} under water.

In 2003, it was determined that Sacramento had both the least protection against and nearly the highest risk of flooding. Congress then granted a $220&nbsp;million loan for upgrades in Sacramento County.<ref>{{cite web|url=http://goliath.ecnext.com/coms2/gi_0199-705251/Sacramento-flood-protection.html|title=Sacramento Flood Protection|url-status=live|archive-url=https://web.archive.org/web/20110809012610/http://goliath.ecnext.com/coms2/gi_0199-705251/Sacramento-flood-protection.html|archive-date=August 9, 2011}}</ref> Other counties in the valley that often face flooding are [[Yuba County, CA|Yuba]], [[Stanislaus County, CA|Stanislaus]], and [[San Joaquin County, CA|San Joaquin]].
