Two branches of the river Cher run through the heart of the town of Châteauneuf-sur-Cher: the main branch and the floodway. After having acquired a 300 linear metre white water course downstream of the secondary branch of the river Cher, the town of Châteauneuf-sur-Cher decided to build a white water stadium upstream of the first course.
An artificial by-pass river was created on the left bank of the secondary branch of the river Cher in order to by-pass an existing weir.
The works carried out (upstream/downstream) favour the practise of general white water sports, and more especially canoe and kayak sports, as well as fish migration. They make it possible to organise regional or even national canoe and kayak events.
The entrance to the river is equipped with a vane which is used to regulate the incoming water flow. During the low water season the pumping station serves to operate the white water stadium (three 1.5m³/sec pumps). The river is designed as a U in order make it quicker for participants to return to the starting pool once they have finished a descent.
The river has a variable width in order to offer interesting water movements for white water activities.
It is equipped with Omniflots® mobile obstacles. Since 2008, HYDROSTADIUM proposes new anchoring systems for river obstacles which make it possible to vary how they are placed, improve the aesthetics of artificial rivers, and make it possible to vary in-depth water movements and make the fitting of the Omniflot® easier for the company in charge of the works. The Châteauneuf-sur-Cher white water stadium was also the first to use the new 2008 generation mobile obstacles.
