The competition whitewater course is 300 m long, with a 6.5 m drop, making a 2.2% slope of 114 ft/mile or 22 m/km. The natural flow of the Segre River is diverted through the course by a diversion dam upstream. In low flow conditions, four 300-kilowattt recirculation pumps can add up to 12 m³/s to the course flow, in order to increase it to the course maximum of 17.5 m³/s. When the course is not being used, or when the natural flow exceeds 17.5 m³/s, the pumps are reversed and run in turbine mode to generate electricity for the town.
A 130-metre beginners course is a diversion from the main course. Its drop is 1.5 m for a 1.2% slope of 61 ft/mile or 12 m/km. Streamflow for the beginners course is 3 to 10 m³/s.
The park also has a 650-m long feedwater canal which carries water from the river into the whitewater course. This canal is used for flatwater canoe and kayak training and competition.
