Before reaching the Channel, its waters are barred by a 750 metre long dam forming the Rance tidal power plant.

The river is linked to the Vilaine by means of the Ille-Rance Canal.

Hydrology and water quality

Tributaries of the Rance include:
* Croqueloir
* Clergé
* Fremeur
* Quinéford

This river has moderate turbidity and its brownish water is somewhat low in velocity due to the slight gradient of the watercourse; pH levels have been measured at 8.13 [Hogan, C. Michael, "Water quality of freshwater bodies in France", Lumina Press, Aberdeen, Scotland(2006)] within the city of Dinan and electrical conductivity of the waters have tested at 33 micro-siemens per centimetre. At this reference location, summer flows are typically in the range of 500 cubic feet per second.
