State fill = trigger viability ( strong · moderate · weak). Gauge colour = wet-season correlation with Floodscan: ρ<0.6 · 0.6–0.7 · ≥0.7. Large black-ringed dots are included trigger gauges; blue-ringed dots are GloFAS stations. Selecting a state enlarges its trigger gauges and fades everything else.
One point per flood season (Apr–Mar). Peaks co-move along the river, but magnitudes aren't comparable across states — SFED scales with local floodplain width.
One point per season; dashed line = consensus fraction needed to fire. A clean trigger puts 4-yr floods (top) right of the line and quiet seasons left of it.
