Bog/wetland for large pond

[Medic75]

Hello
First post here.
Question about building a large bog/wetland filter for my pond.
A little about my pond
Newly dug Dec of 21 natural clay bottom, it's 150'x330' average depth 20' with a hole to 35'. Approximately 4 million gallons
We are using it for a swim/fish (rainbow trout) pond that is in our front yard visible from house. Some of the dirt banks are still there and thinking of integrating a stream waterfall into them.
Now for the bog...
At 30% that would mean 45'x95'ish wow that seems like a huge area. Yes I know my pond is large and will need a big bog but do I need to go that big?
Thank you for any insights.

That is ideal the 30% surface area, but anything is better than nothing, and adding plants to the main pond will help, as well. You can also add one bog that is smaller or fits the area you have in mind and see how it does, if it’s not enough you can add another one in a different spot.

Wow that is really huge and beautiful! Going to look so nice when you add more plants also.
