Duck Pond Help

[HorseMadWhovian]

I need some help with a duck pond, I have a child's pool at the moment which only needs cleaning once a week but is blow up so I prefere to supervise the ducks in it. What are some ideas for an easy to clean in-ground duck pond. We have a dam and my dad wants to set the ducks free in it but I would never catch them again and they would fly off. I've had these ducklings since the minute they were born and they don't have any survival instincts, really they don't. I'm 13 and live on clay so I need something thats easy to keep clean etc. I need to be able to do it all myself so nothing extremely complicated, my ducklings are in their own 2 by 8 metre run but I plan on making a bigger area for a pond. They are ranged in a large area every day and get about 30 -60 minutes swimming if I can at the moment its holidays so they get that every day I'd like something more permanent before school starts.
Please Help
Thanks

i use in of those hard plastic kiddie pool i put it in the ground and only have to clean it once a week or you can leave it out of the ground and dump the water out with a bucket and just turn it up and clean it out with a hose i think my pool is really easy to clean i m sure some one has some thing better to tell you but this is what works for me

We put one of those hard plastic pond forms in, only we put in on a hill and dug flat an area for it to sit (the front side of it is exposed on the side on the hill). We then drilled in a hole near the bottom and placed a drain spout and hose. We put a brick retaining wall up in front of the exposed side (just stacked cinder blocks) with an opening to reach in and control the spout.
It gets water added and a swishing every few days and then I drain it every couple of weeks in to a bucket and I water flower beds and such with the water.
