Floods and seasonal variation

The rate of flow of the Doubs is very seasonally variable. The flooding or well-watered season can stretch from September to May, caused by heavy rains or by quick melting of snow from the Jura mountains. At its mouth, the discharge rate can vary from as low as to over during floods. In Besançon, the largest floods have been in 1852 (), in 1896 () and in 1910.

Hydroelectricity

As a mountain river with substantial discharge, the Doubs has been used for electricity generation. Among several hydroelectric stations, the most important are the Dam of Châtelot, tall, and the Dam of Refrain, tall.

In popular culture

The river is mentioned sixteen times in Stendhal's novel '' The Red and the Black'' (''Le rouge et le noir'').
