Travis is rising (+4.27 ft this week). More water is coming in than releases, evaporation and intakes take out. That puts it in the “Near full” range, 0.62 ft below the “In the flood pool” 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 4 river gauges (USGS or LCRA, whichever is newer), plus yesterday's average dam releases (LCRA). 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. LCRA’s daily storage for the lake changed +574 af ≈ +0.36 in on Nov 13.

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