It was you who opened up springs and streams; you dried up the ever-flowing rivers.
NIV
You did cleave open [the rock bringing forth] fountains and streams; You dried up mighty, ever-flowing rivers (the Jordan). [Exod. 17:6; Num. 20:11; Josh. 3:13.]AMP
Thou didst cleave the fountain and the flood: thou driedst up mighty rivers.
