由于纳玛达巴超安杜兰反对派的抗议,使原计划关闭泄水闸的时间由1991～1992年雨季推迟到1994年2月。在关闭闸门后,总渗漏量达40m~3/s。通常对这种情况的处理措施是在闸上游用填充料堵塞缝隙,但这样做既费时又昂贵。漏水由下列因素造成:冲刷引起原来河卵石移动;由于闸门和底梁间高速水流引起床面上底板或支架和结构钢架等的变形;闸墩止水差。

As a result of the opposition from the Nhadamba Ondurran opposition, the planned time to close the sluice was postponed from the rainy season of 1991-1992 to February 1994. After closing the gate, the total leakage of 40m ~ 3 / s. Often this is done by filling up the gap with packing material upstream of the gate, but doing so is both time-consuming and expensive. Leakage caused by the following factors: Scour caused by the original river pebbles move; due to the high speed flow between the gate and the bottom beam caused by the bed floor or frame and structural steel frame deformation;
