  • Description

    A FOUR-MILLION POUND BARRAGE OF UNUSUAL DESIGN, TO CONTROL THE FLOW OF THE RIVER LEK, A BRANCH OF THE RIVER RHINE AND AN IMPORTANT RIVER TRAFFIC WATERWAY ACROSS THE NETHERLANDS TO ROTTERDAM, WAS OFFICIALLY OPENED AT HAGESTEIN, NEAR UTRECHT, AFTER SEVEN YEARS IN CONSTRUCTION.

    THE BARRAGE CONSISTS OF TWO SEMI-CIRCULAR STEEL GATES, EACH WEIGHING ABOUT 250-TONS, WHICH CAN BE LOWERED ON TO CONCRETE SILLS ON THE BED OF A NEW CHANNEL, OR RAISED HIGH ABOVE THE SURFACE OF THE WATER BY HIGHLY GEARED MACHINERY OPERATED BY FOUR ELECTRIC MOTORS, THE COMBINED POWER OF WHICH IS ONLY 24-HORSE-POWER. THE RAISING OR LOWERING OPERATION TAKES, HOWEVER, APPROXIMATELY 2 1/2-HOURS.

    THE RIVER LEK IS ABOUT 360-FEET WIDE AT THIS POINT, AND IN ORDER TO CONSTRUCT THE BARRAGE A NEW CHANNEL WAS DUG, ACROSS WHICH THE BARRAGE WAS BUILT BEFORE THE RIVER WAS DIVERTED. PARALLEL WITH THE NEW CHANNEL, A LOCK HAS BEEN BUILT TO ENABLE THE HEAVY RIVER TRAFFIC TO PASS UNHINDERED WHEN THE BARRAGE GATES CLOSE THE MAIN CHANNEL. PIERCED THROUGH THE CONCRETE PIERS ON EITHER SIDE OF THE BARRAGE ARE TUNNELS TO ENABLE EELS AND OTHER FISH TO MOVE UP AND DOWN THE RIVER.

    TWO SIMILAR BARRAGES ARE TO BE BUILT FURTHER UPSTREAM. THE OBJECT OF THE SCHEME, WHICH WILL NOT BE COMPLETED FOR SOME YEARS YET, IS TO PROVIDE FOR CONSTANT AND PRECISE CONTROL OF THE LEVEL AND FLOW OF THE RIVER -- FOR A NUMBER OF IMPORTANT PURPOSES. ONE OF THESE IS TO BANK OFF THE LEK'S WATERS AND FORCE PART OF THEM TO FLOW DOWN THE RIVER IJSEEL INTO THE FORMER ZUYDER ZEE, NOW THE IJSEEL LAKE, WHERE MORE WATER IS NEEDED FOR AGRICULTURAL AND OTHER PURPOSES IN THE GREAT NEW AREAS OF FARMLAND RECLAIMED FROM THE LAKE. ANOTHER PURPOSE IS TO CONTROL THE FLOW OF WATER DOWN THE LEK TO THE POINT, NEAR ROTTERDAM, WHERE IT MEETS TIDAL WATER COMING UP FROM THE SEA, AND FORCE IT BACK INTO THE SEA. AT PRESENT, SEA WATER SEEPS UNDER THE DYKES, AFFECTING SUBSOIL OF AREAS LONG RECLAIMED FROM THE SEA, AND CAUSING LOSS OF LAND FERTILITY.
