The Don (French pronunciation:[dɔ̃]ⓘ) is a river in Brittany, northwestern France. It is a tributary of the river Vilaine. It is 92.1 km (57.2 mi) long.[1]
The Don has a very irregular flow rate over the months, like other tributaries of the Vilaine.
The flow of the Don was observed and documented in a study which took place over a period of 25 years (1983-2007). The results were taken from near the Don's confluence with the Vilaine. It showed that the average annual flow rate 3.77 cubic meters per second. However, the Don has strong seasonal fluctuations in flow rates, in common with other tributaries of the Valaine, and other rivers of Brittany. The highest waters occur in winter, and are characterized by average monthly rates ranging from 5.95 to 11.7 cubic meters per second. From March, the flow decreases rapidly, to the lowest water in summer from June to mid-October. The results are clearer in the bar graph, below.
