It is not all dried up. Not yet. You can walk to Antelope Island from the south shore. The harbor is devoid of all boats because there is not enough water to keep them clear of the mud bottom. Does this help?
Not virtually dried up. But about half gone. Most islands are now peninsula.
Google has good shots.
As a funny note.
I had an anti mormon person tell me if women refused to marry Brigham Young he'd take them to the top of the Salt Lake Temple and toss them in the Great Salt Lake.
