"The agency has been operating streamgages in the United States since the 1880s. One of the first 120 gages the agency installed was in Wisconsin in 1899 ... That longevity gives scientists an essential resource for tracking Wisconsin’s bodies of water." via @wisconsinexaminer.com

I've reached out to multiple authors this week to try and get data from their papers. So far, all I've got is a collection of bounced emails.

Musk’s status as a “special government employee” limits him to 130 days in the executive branch. However, despite working daily—documented by his own X posts—they claim he only works one day a week, effectively stretching his limit to 130 weeks. This needs to be brought to Congress—please share.

Every scientist, long before they were a scientist, was a little kid who stood in front of a fish tank or stared up at the stars or turned over a rock to look at the bugs underneath and said “wow”. On the best days, working in science still feels like that.

All are welcome to participate! Please remember to share the code used to generate your results!
TidyTuesday is organized by the Data Science Learning Community. Join our Slack for free online help with R and other data-related topics, or to participate in a data-related book club!

 How to Participate
Data is posted to social media every Monday morning. Follow the instructions in the new post for how to download the data.
Explore the data, watching out for interesting relationships. We would like to emphasize that you should not draw conclusions about causation in the data.
Create a visualization, a model, a shiny app, or some other piece of data-science-related output, using R or another programming language.
Share your output and the code used to generate it on social media with the #TidyTuesday hashtag.Three choropleth maps of the United States west of the Mississippi River, using 2022 U.S. Census Bureau Data, entitled Mapping water insecurity in R with tidycensus. The first choropleth is labeled Percent Hispanic, 2022, and shows the highest percentages of Hispanic people near the US-Mexico border, with scattered high percentages, such as in the state of Washington. The second choropleth is labeled Median gross rent, 2022, and shows the highest rents in California, Washington state, and Colorado. The third choropleth is labeled Average household size, 2022, and has scattered areas of large household size, with the highest averages in South Dakota, Utah, southern California, and southern Texas. The image also includes the hex logo of the tidycensus R package, with an indistinct choropleth map in shades of green.

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.
