Keep in mind I am not a pro...

I calculate a 50 foot wide pond would only be 5 feet deep at a 5:1 slope and a V shaped bottom. If you wanted a pond 10 feet deep with say a 50 foot wide flat at the bottom, the pond would be 150 feet wide at the surface.

I got by last winter with only 8 feet depth. This summer I added two areas of 12 feet deep water and I am much more comfortable this winter. I am not a pro but IMHO Rule of thumb with a water table pond is "the deeper, the better."

FWIW I recommend aeration to prevent stagnation and "stinky" water.

Hopefully, one of the pros will be along to offer some sage advice.
