The power jet also allows deeper dredging because the power jet will lift material higher than a suction nozzle can push it. The disadvantage of the power jet is that the power jet and supply hose must be kept under water at all times. Therefore they do not work very well when working in shallow water.

(see lecture notes wb3413 the Braching process)During sand dredging the dredger is moved slowly forwards by a set of winches. To increase the amount of sand flowing towards the suction mouth, a water jet is often directed onto the breach/bank. In this case the jet-pipe is often mounted above the suction pipe.

This may be because the size of the pond is smaller or because there's less muck to dredge up. In either case, the task will be less difficult, meaning that while a large dredge would certainly do the trick, it may also be more powerful than is necessary for this work.
