One thing about Dwarka - the reason Krishna had it set up as an island was so that it would be inaccessable to all other armies - Magadha, Kuru, Avanti, Chedi, Sindhu, et al. Jarasandha pretty much had to give up any hopes of invading it, and the only ruler who even tried was Shalva. Otherwise, nobody - not even Karna - tried invading Dwarka ever, and that made the Yadavas feel absolutely invincible.

But that brings up a different question - how did anybody from the mainland - Arjun, Sudama, or anyone else for that matter, ever come to Dwarka? Was it accessible by bridge, or by boats? When they say that Sudama came to Krishna, that would mean what - that after he arrived @ the opposite coast, he took a boat and went to see him?

And when Arjun evacuated the city, how would he have done it? Have a whole navy that would have taken everybody to the mainland, and then moved on? Incidentally, Sudama would have taken some days to get from Porbandar to Dwarka, but the Pandavas, after abdicating the throne for Parikshit, went on a pilgrimage to Dwarka, where Arjun returned his Gandhiva to Varuna. After visiting Dwarka and paying homage to the fallen Yadavas, they again turned back and went to the Himalayas, where they all met their final end.

Where is Prabhasha - the place that the Yadava fratricide happened - wrt Dwarka?

You can visit the city even today, you can go underwater and see all of the ruins, I really want to go!!
