This hydrograph of the Guadalupe River in Comfort is terrifying with this…something like 25 feet in 45 minutes.

The Hurricane Erin pressure plot looks like the Suicide Basin hydrograph from several days ago. Makes you think. 🤔

Hydrologists! Ever heard of a Spatial Hydrograph? Our new paper in @agu.org GRL shows that the SWOT satellite can capture spatial flow waves propagating down rivers—something previously only only observable at river gauges: doi.org/10.1029/2024...

It would be interesting to see the hydrograph for this event on our local unnamed stream.

According to NWS, San Francisco just recorded the highest Summer water level on record. #KingTides

Morning on the Truckee River
531 cubic feet/second ≈100 less than median flow. The hydrograph had a very significant pulse in February where it was 1730 ft3/s as compared to the median for that date of ≈400.
USGS Gage at Farad, CA.
Inanycase use that free government data while you still can.

Chena River in downtown Fairbanks at the highest level for this point in the season (since 1948). No wonder: total rain for the month through the 19th:
Fairbanks Aprt: 3.80", UAF: 4.03"
South Fox: 4.41"
Keystone Ridge (Murphy Dome area): 6.60"
Munson Ridge (south of Chena Hot Springs): 8.9"

Absolutely insane hydrograph. Storm over central TX, Guadalupe river cresting over 34' when it was 3' just hours earlier.
Friends have sent images/videos and it is wild. Stay safe out there y'all

Look at that hydrograph! This is from a USGS monitoring well in Christiansburg, Montgomery County, VA. Observation well 27F2 SOW 019 is 450' deep, completed in carbonate rocks of the Elbrook Formation and well known for its response to quakes.

NOAA has hydrograph readings along the Guadalupe River that includes actual & forecast water levels. When Irene hit VT, I used the hydrograph readings on the Winooski River & realized I would need to be evacuated overnight, so I moved to higher ground ahead of time. Were they used in TX?

There were two big streamflow pulses since 1 Oct 25. iirc these were due to “rain on snow” events, which sucks for the water storage potential in the Sierra Nevada snowpack.
2590 cfs - 22 Dec 25
2280 cfs - 25 Feb 26
Water Year 2025 for comparison with a big pulse but traditional peak flow season.

Long day in the flume lab today 😅
Ran two flood hydrograph experiments looking at the transition from dunes exhibiting dune group behavior to large dunes with superimposed smaller bedforms. Looking at flood length an stratigraphic preservation 🤓

The Rio Grande’s Institutional Hydrograph: December 2025
After a dry summer, the Rio Grande is up through Albuquerque – ~900cfs as I write this, above the median flow for early December. We are heading into “institutional hydrograph” season, as wat…

Correction, misread the hydrograph, crest actually comes on Mendenhall by early Thursday - article updated
