What river was especially cursed by God in Section 61 of the Doctrine and Covenants?

Lord cursed Lamech, and his house, and all them that had covenanted with Satan. The Book of Moses 5:52

For I, the Lord, have decreed in mine anger many destructions upon the waters; yea, and especially upon these waters. Doctrine & Covenants 61:5

I, the Lord, have decreed, and the destroyer rideth upon the face thereof, and I revoke not the decree. Doctrine & Covenants 61:19
