The Thur is a 53 km long left tributary of the Ill in Alsace ( Grand Est region ).
geography
course
The Thur rises in the Vosges on the southwest flank of the Rainkopf north of Wildenstein . In Kruth 1959-63 a dam was built to the drain especially after the snow melts to regulate. This created the Lac de Kruth-Wildenstein .
The Thur then flows through the Thurtal , formerly often called St. Amariner Tal , (Vallée de la Thur), past Saint-Amarin , Thann and Alt-Thann before entering the Upper Rhine Plain and turning northeast at Cernay . Below Ensisheim it flows into the Ill . An arm branching off in front of the mouth flows further north as the Alte Thur , past Rouffach and flows into the Lauch below Pfaffenheim . This is the main reason why the Thur has an average of around one sixth less water at its mouth than at the Pulversheim gauge (a good 6 m³ / s).

Hydrology
At the confluence of the Thur and Ill , the mean discharge rate (MQ) is 5.18 m³ / s; the catchment area here covers 261.7 km².
At the Pulversheim gauge , the average annual runoff of the Thur was calculated over a period of 35 years (1974–2009) . The catchment area at this point, with 250 km², corresponds to about 95.5% of the entire catchment area of the river.
The flow rate fluctuates quite strongly over the course of the year. The highest water levels are measured between December and March. The flow rate reached its peak in January at 11.40 m³ / s. From April onwards the discharge decreases month by month and reaches its lowest level in August with 2.04 m³ / s, after which it increases again from month to month. The annual average value here is 6.19 m³ / s.
The monthly mean discharge (MQ) of the Thur in m³ / s, measured at the hydrological station Pulversheim.
