ROMS Lake Jersey ques

[Honolulu_Wang]

Hello All,

I am going through this ROMS Lake_Jersey example.
I have a very basic question, is this lake a real lake, since I see a lot of strong surface gradient in salinity and temperature? Could lake have so high-density gradient?

Or this is just for a test case.

Since I want to use ROMS for some sale inland scale lake, about (3km to 10km) *(3km to 10km).
Could ROMS do that?

Thanks
