How to manage a Duck Pond ?

What is the best way to manage a duck pond without running water ? Should it be emptied completely from time to time or just topped up now and then.

Hi

A couple of years ago I reared 25 mallard for our shoot from day old chicks. The amount of poop they make in relationship to their size , is unbelivable something to do with a simple gut system. I had a bath in the run that the water had to be changed every day. If I let a few stray onto our fish pond the first thing they do is poop in the water and sent it cloudy .  My sister has a six in her garden and the pond water is changed reulaiiy ir it becomes foul.

About 8ft by 8ft and 3ft deep. there are only 3 ducks using the pond so it does not get to messy, but will the water need changing it's quite green.

We've got a biggish pond with 2 grown geese on & thats emptied weekly. It's about 4 foot deep & 8 ft x 4ft. Also had ducks in the past on it too. Both poo lots which sits as sediment on bottom. In summer it turns the water green if left a bit too long. I use a submersible pump & thick drain hose direct into the drain. It absoluetley stinks!! Great on the garden though. Then refill with garden hose.

All waterfowl love a pond.

thanks for all the advice , but i was wondering how to empty the pond ? do not have a submersible pump , guess it will have to be a bucket 

There's a tradition in some parts of the world to raise carp in duckponds to make the best use of the nutrient rich water.  Not practical with a small volums of water..

Update: cleaned the pond , had to use a bucket because the siphon was clogged up  . It was not too smelly, must be because the pond is under a tree and in the shade. There was only 6inches of silt. Thanks for all the information and help
