In this paper, we critically assessed how the SWOT discharge algorithm BAM/geoBAM perform at three-thousand distinctly located rivers globally. This is one of the few studies that prioritized "global generalizability" over "perfect skills at limited places", where promises and challenges are discussed. We believe similar large-scale assessment would be key to identifying emerging challenges as we move into the new era with global river monitoring capability from space.
