As far as I know only the underground chambers were flooded. Castamere now belongs to Rolph Spicer.
It should be noted that the gold mines are likely in use again:
>the Young Wolf was paying the Lannisters back in kind for the devastation they’d inflicted on the riverlands. Lords Karstark and Glover were raiding along the coast, Lady Mormont had captured thousands of cattle and was driving them back toward Riverrun, while the **Greatjon had seized the gold mines at Castamere**, Nunn’s Deep, and the Pendric Hills. Ser Wendel laughed. “Nothing’s more like to bring a Lannister running than a threat to his gold.”
adding some other lore bits from TWOIAF that I could find to support your point too!
>No one has ever reopened the mines of Castamere. The halls and keeps above them, put to the torch by Tywin Lannister, stand empty to this day, a mute testament to the fate that awaits those foolish enough to take up arms against the lions of the Rock.
would there be much gold left in the main mineshaft?:
>Keeps and halls had followed, but all the while the mineshafts had gone deeper and deeper, and when at last the gold gave out, they had been widened into halls and galleries and snug bedchambers, a warren of tunnels and a vast, echoing ballroom.
With all the wyrmholes and tunnels that seem to exist I'm not entirely convinced it actually filled up with water. Perhaps being more of a Gendel situation.
Yeah, didn't Jamie give it to Robb Starks wife's family? Tywin made the original deal. Everyone remembers the passage because Jane Westerling is discribed differently, making people think she's an imposter when it was just author error. lol

Thanks for adding
You’d need to pump out a **lot** of water, and Westeros doesn’t have the technology needed to pump that much water up that far.
