water turned to blood

EX. 7:20 And Moses and Aaron did so, as the LORD commanded; and he lifted up the rod, and smote the waters that [were] in the river, in the sight of Pharaoh, and in the sight of his servants; and all the waters that [were] in the river were turned to blood.
was Pharaoh in the water when it turned to blood?

I think Pharaoh was standing by the river's brink too:

Ex. 7:15 Get thee unto Pharaoh in the morning; lo, he goeth out unto the water; and thou shalt stand by the river’s brink against he come; and the rod which was turned to a serpent shalt thou take in thine hand.
