Wake size bigger in deep water???

Hi,

Yesterday I tried out a new lake and the wake behind my boat was 50% bigger than normal.
(Same exact setup)

The only difference was the lake.
I usually ride on lake about 20ft deep and this lake was about 75ft deep.
Would this make a difference?

Or could there be a difference in the water itself?

Has anyone else experienced this?

All I know is that I am going to have to frequent this lake a LOT more!
