Would also love resources if you have good ones to share! Been building some guides for students.

We hope that everyone had a happy first day of the 2026 Water Year!

Tomorrow is the first day of Catchment Cup! Check back in the morning when the first round of polling opens up for Headwater Catchments!

We are so excited to share facts and research from early career researchers at these sites!

Brought cookies to my surface water hydrology class to celebrate today 😂

Just bad coincidental timing! I didn’t remember anything going offline during past shutdowns.
sledford.bsky.social
It’s a planned outage, not shutdown related. Hopefully back up soon.
sledford.bsky.social
Update: a known outage and not related to the shutdown is what I’m hearing. Sounds like it was listed in the newsletter.

Many USGS gages across the country have stopped updating. Anyone know what’s going on? This shutdown related? They seemed to all stop 16 hours ago, at least in Georgia.

It’s never been great but I agree with Nicole, seems fully broken right now.

Yeah, I think Hannah is pulling from the USGS NHDPlus which is good for Atlanta for everything above ground, but doesn’t capture those buried streams. Thanks for reminding me that she had those maps!
sledford.bsky.social
Good to know you haven’t found it either! Taylor and I may just need to find a student to sit and do it. Thanks!

Out of curiosity, do you know if anyone has digitized the locations of the former stream channels across Atlanta?

I’m proud to say that @noaa.gov and NCEI has released a 1 year retrospective on #Helene using ESRI Story Maps.

Here is a brief thread of how this came to be and how NOAA can still do good things (even while wearing pajamas).

The most useful and useful impactful classes I took during my PhD were at ESF. It’s an amazing school always working on a shoestring budget. Cutting more will just decimate it and the amazing work it does.

Our president thinks that asking faculty and staff to voluntarily quit is a better solution than advocating for restoration of our mission funding from SUNY and being a more effective fundraiser. Meanwhile her high-paying job is safe.

How can you help us?

I accidentally saw the video. Do yourself a favor and don’t.

Do you know the gage number?
sledford.bsky.social
Yeah, I noticed that precipitation disappeared from the USGS water dashboard for sites I know it’s being measured. I’ve had to go to the legacy real time page for some gages to find data recently.

Discussions of the destruction of the CDC, HHS, etc. by RFK Jr that do not lay a hefty part of the blame on Senator Cassidy feel woefully incomplete. He could have stayed true to his principles as a medical professional and blocked RFK's confirmation. He did not and he should not be given a pass.

Where was this announced?
sledford.bsky.social
This paper shows, once again, the importance of community science but also how hard it is to have safe, swimmable streams in urban environments- almost all sites had long-term median E. coli levels way above what is allowed by the state.
sledford.bsky.social
While we didn’t find correlations to race, watersheds with more dense urban infrastructure are more likely to have high E. coli measures- potential indicator that sewage infrastructure density or potentially age related to high E. coli.
sledford.bsky.social
Hydrology drives at most about 50% of temporal variability in E. coli. The shifting patterns in point vs non-point source behavior make predicting E. coli very difficult.

A mile from my house. That intersection is awful.
