The Ternoise is a very uniform river. Seasonal flow fluctuations are very not very marked, similar to the Canche or the Somme, its neighbours. The higher water flows occur at the end of winter and in the spring. Average flows vary between 3.44 m³ per second in September to 5.36 m³ per second in March.
