Thanks for support!
Well, I have no idea how large could they grow in a pond. I don't see any reason why they couldn't reach several kilograms in weight but... everything takes time and some of these might be eaten till that. You see, I don't keep fish for pleasure fishing only. They are eaten as well.
If you are interested in possible zander size in Latvia then I can tell you that the official record is approx. 12 kg. There are a few lakes and rivers where this fish grow that large.
Here is the picture of that record fish:



Well, there are even heavier ones. This one has been caught in my neighbouring country Estonia by fishermen. 17 kg:



Sure, it's hard to think about such fish in a pond.

I mentioned some dirt works before.
How it looked in 2012:




And now:





For better understanding I've added a scheme (sorry for the poor quality - done in a hurry):



1 - existing pond;
3 - that new pond you can see in the pictures;
2 - there used to be a swamp. Now that place has been used for storing the dirt;
4 - if everything goes right, this area could be flooded (a bit of it next year and everything after some years). After some improvements of existing dam, at least 2 additional metres of water level can be raised.
