At leaSst some of the CO2 in a lake will be released to the air or to plant life.

If the volcanic magma can carbonate a lake then it surely can carbonate and aquifer. Since the magma and the rising mountain are continually tipping the aquifer basin then at some point it can be essentially emptied so there is no more flow of CO2 into the aquifer.

There would be very high water tables during the inundation. There was apparently a river flowing west to east just north of Giza and if large amounts of water were coming up in this region there would be a more minor tributary flowing north nearly from Lake Moeris.

The Nile once flowed a little west of Giza. When the "Great Green" was cut off from the world's oceans the level dropped hundreds of feet which caused the Nile to carve a deep canyon all the way to Aswan. Eventually the connection was reestablished and the canyon flooded becoming a fiord. This took many tens of thousands of years to fill in but it would have created numerous caverns and caves in the surrounding area as it did. About the time it completely filled the river switched to the east side of Giza.

Since the water came from higher areas there's no reason that it can't be very high on the Giza Plateau. Even today there are trees in the area with their roots extending deep to the water table.

There was a great deal more water in antiquity. Horapollo claimed that the ancients believed water came from the ground.
