The Théols is a {{convert|42.3|km|mi|adj=mid|-long}} river in central France.{{sandre|K61-0310|La Théols|consulté le=22 December 2011}}

Hydrology
The flow of the river was studied from 1971 to 1975 at Sainte-Lizaigne, located about {{cvt|10|km}} from its confluence with the Arnon. At this point it drains {{cvt|797|km²}}, over 90% of its watershed.
The river has an average flow of {{convert|2.99|m3/s|abbr=on}} at Sainte-Lizaigne.
There are seasonal fluctuations in the flow of the Théols, but they are not substantial. The highest flow rates are from February to May, with average flows from {{cvt|3.5|to|5|m3/s}} (peak February–March). From April, the flow rate decreases regularly toward low water, which lasts from August to October. Floods are seldom important. The daily maximum flow recorded at Sainte-Lizaigne was {{cvt|32.3|m3/s}} on March 22, 1974.
Its yearly drainage basin precipitation is currently {{cvt|118|mm}}, just over a third of the national average of {{cvt|320|mm}}, and also below the average of for the Loire basin ({{cvt|245|mm}}) and the Arnon ({{cvt|200|mm}}). The discharge was hence {{cvt|3.75|L/s}} per km² of basin.
