Hydrology

At the mouth of the Mossig into the Bruche, the mean discharge (MQ) is 0.58 m³/s; the catchment area here covers 169.9 km².

At the Soultz-les-Bains gauge, the average annual discharge of the Mossig was calculated over a period of 41 years (1970-2010).[3] At this point, the catchment area of 163 km² corresponds to about 96 % of the river’s full catchment area.

The discharge fluctuates quite strongly in the course of the year. The highest water levels are measured in the months of January – March. The discharge reaches its maximum level of 2.13 m³/s in February. From April on, the discharge decreases and reaches its lowest level in September with 0.66 m³/s, only to increase again from month to month.
