Built in 1983 in Czechoslovakia, it diverts water around a 3.6 metres (12 ft) dam at Troja on the Vltava river in Prague.

Its two unique features are its use of car and truck tires as flow diverters and its shallow slope, closer to 1% than the usual nearly 2% for such venues.

[2] The channel walls are vertical, with flow diverters constructed of automobile and truck tires stacked side by side to form large cylinders attached to the bottom by beams running through the tires.

In the centre of the flow are smaller automobile tires which remain submerged, and shallow-sloped ramps.

In several spots, new concrete platforms have been installed in the channel bed to receive moveable RapidBlocs, like the ones at the Lee Valley White Water Centre used for the London 2012 Summer Olympics.
