why didn't elrond help?

[Legolas]

Elrond sent the rush of water that overcame the Nazgul at the Ford of Bruinen. He healed Frodo upon his arrival to Rivendell. When Gandalf did not return from Orthanc, he sent out messengers that gave him news of the Nazgul in the region near the Shire and afterwards sent Glorfindel to search for Frodo.

`Good!' said Gandalf. `It is mending fast. You will soon be sound again. Elrond has cured you: he has tended you for days, ever since you were brought in.'
'...Elrond is a master of healing, but the weapons of our Enemy are deadly. To tell you the truth, I had very little hope; for I suspected that there was some fragment of the blade still in the closed wound. But it could not be found until last night. Then Elrond removed a splinter. It was deeply buried, and it was working inwards.'

`Who made the flood?' asked Frodo.
'Elrond commanded it,' answered Gandalf. `The river of this valley is under his power, and it will rise in anger when he has great need to bar the Ford. As soon as the captain of the Ringwraiths rode into the water the flood was released.'
