The invention concerns an obstruction device for flowing waterways and rivulets of all kinds, in particular for torrents and similar river beds, with a flexible barrier element in the form of a catchment net (4), extending from one riverbank (2) to the other riverbank (3) transverse to the flow direction (7). The catchment net (4) is installed between a lower support rope (5) and an upper support rope (6). The support ropes (5, 6) are anchored in the riverbanks (2, 3) with rope anchors (8, 9) attached to their ends, whereby the rope anchors (9) of the upper support rope (6) are offset to the front relative to the rope anchors (8) of the lower support rope (5) in flow direction (7). In this way the catchment net (4) can deform itself when the barrier is filled in such a way that the water, rocks, flotsam etc. then overflowing the net will contact the same either not at all, or only briefly. In this way it is safely and permanently protected against the corrosion and abrasion effect of the overflowing water.
