6 or 7 feet in some areas from what I remember from the dredging. The goal was to have it back to 6 feet deep in certain areas; after years of use caused it to be very shallow of around 6 inches. That wasn't healthy for all of the creatures that reside there.
It's not to deep but like others have said it's deeper in other area's.
It's different in different areas. I've never really been worried about how deep it is since we can't swim in it.
