Powell is rising (+1.40 ft this week). More water is coming in than releases, evaporation and intakes take out. That puts it in the “Ramps closing one by one” range, 48.50 ft below the “Healthy modern levels” line.

SteadyReceding · high water draining downOn the rise · climbing right nowInbound wave · big rise upstreamFlooding · NWS, by river heightNo current readingRising or falling is judged from each gauge’s last 48 hours, scaled to its river. Dot speed follows the flow. NWS flood status comes from river height and outranks direction.

Streamflow at the 3 USGS gauges, plus the current flow out through the dam (USGS). Labels are gauge readings in cfs. Line width isn’t to scale. The lake’s net is worked out from these gauges (flow in minus flow out), so it misses ungauged creeks, evaporation and withdrawals. Reclamation’s daily storage for the lake changed +8,807.09 af ≈ +1.54 in on Nov 13.

Gauged rivers only. Runoff below these gauges and ungauged arms aren’t counted. Streamflow: USGS (provisional). Flood status: NOAA/NWS, from river height at each gauge rather than flow.
