I study small fish in small streams and co-lead a team that makes interactive data viz tools to help make complex data and models easier to understand: www.usgs.gov/apps/ecosheds and now westbrookdataviz.org

Great #handsoff turnout in Boston!

This is so low. Maine Sea Grant apparently just got shut down to punish the governor. #thishastostop

New USGS hires at our lab just got termination letters. Horrible for our research but truly devastating for them. #executiveoverreach

The U.S. Geological Survey (USGS) Vizlab has just released a new, interactive data visualization website about the USGS National Water Availability Assessment Report and Data Companion. Explore the data and the key findings of the assessment at water.usgs.gov/vizlab/water... #DataViz #rstats #USGS

Stylized illustration of the water cycle of the lower 48 United States, showing the fate of water that enters through precipitation. Most of the water returns to the atmosphere through evapotranspiration, but much of the water ends up in the Atlantic and Pacific Oceans, in Canada, or in the Gulf of Mexico through streamflow.

Map of water limitation in the lower 48 United States by watershed. Areas with relatively high water limitation are in the high plains, Texas, California, and the Mississippi Embayment hydrologic regions.

A great step towards dynamic scientific articles. [I thought his voice was familiar - he also did that great video on how to make an effective scientific poster that I gave to all my students]

I love the things we see in streams in the Flow Photo Explorer www.usgs.gov/apps/ecoshed.... Here, in Nevada, a tumbleweed hangs around from Feb to May, finally getting pushed out by some high flow. In case you were wondering, it showed up between 11:15 and 11:30 pm on Feb 4 :) #flowphotoexplorer

Do you use trail cameras to monitor streams, rivers or other water bodies? Looking for a platform to turn those images into relative flow or stage information? Or even just to look back through all of your images? Check out Flow Photo Explorer! www.usgs.gov/apps/ecoshed...

With hundreds of cameras and millions of photos in our Flow Photos Explorer, we get some cool wildlife pix (screened by megadetector). See the owl? Nerd alert - we can also tell you within 15 min when the tree top of the stump the owl is sitting on fell. That's got to be valuable to someone, right?

And here are 3 streams in Shenandoah NP during hurricane Helene - yikes!

What happens to small streams during a hurricane? Here are time-lapse photos (every 15 min) from our Flow Photos Explorer of 3 sites in PA during Helene. Shocking how high they get and that any fish can survive. They are so flashy, we might even have missed the peak. [gif by Phillip Goodling]

The number of images in our Flow Photo Explorer is going up, up, up! It uses trail cameras and machine learning to estimate stream flow, especially in small streams. Anyone can use it! Check it out: www.usgs.gov/apps/ecoshed...

Number image is increasing exponentially
