Extended Data Fig. 8: In-state versus upstream out-of-state viable protected river length among pairs of states in the U.S.
From: National assessment of river protection in the United States
Self-links in the Sankey plot represent in-state viable protected river length within state borders and between-state links upstream out-of-state viable protected river length in the watersheds upstream of the focal states but within the same river basins. Protected river length for each state is expressed as a percentage of in-state and upstream out-of-state total river length, respectively, and not the amount of water exchanged.
