Why not use dam as a flood buffer only?

I WISH to make a few points in relation to the opening by the ESB of the Inniscarra dam on Friday, November 20, and the subsequent flooding of Cork city.

The operational water level of the dam was clearly too high to cope with the volume of flooding in the Lee catchment area.

If it is true that, as a consequence of global warming, we must anticipate significantly higher levels of rainfall on a more regular basis, then surely the river management procedures must be adjusted accordingly.
