<p>In this image a man is standing ontop of one of the various river locks of the River Murrary at Renmark. The lock gates close to form a 'V' against the current and upstream water pressure, which helps to keep them closed and make a watertight seal. The pressure of water within the lock chamber keeps the downstream gates closed.

This image has probably been reversed when copied, as indicated by the direction of the water flow.</div>
