River Map

This map plots all 999 USGS stream gauges tracked by RiverTracker. Each marker is colored by current discharge compared with its 7-day average: red means high flow (above 150% of average), amber means low flow (below 50%) and blue means normal. Hover a marker to see its current flow in cubic feet per second, or click it to open the river page with gauge height and a 30-day trend.
