After the flood when God wanted the waters to subside he sent the wind to that
KJV Genesis 8 : 1
And God remembered Noah, and every living thing, and all the cattle that was with him in the ark: and God made a wind to pass over the earth, and the waters assuaged.
Prior to that during creation when God was creating moving things and separating the waters above from those below he spoke directly to the waters.
KJV Genesis 1 : 20
And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl that may fly above the earth in the open firmament of heaven.
KJV Genesis 1 : 9
And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so.
Was there something significant why God didn't speak directly to the waters after the flood.
