See you this week at AGU! We’ll be presenting on all things water, including drought forecasting, modern APIs, science education, data viz, and much, much more! #AGU25 #WaterData #USGS

Pesticide exposure is linked to negative human-health effects. A new USGS study found that pesticides in groundwater rarely exceeded human-health benchmarks, 1993 to 2022. doi.org/10.3133/sir202… #WaterQuality #WaterUse #Pesticides

Mapping rivers just got easier! 🗺️💧 Our new blog displays how to create beautiful and reproducible river maps. #nhdplusTools #dataRetrieval #ggplot #rstats 🔗: waterdata.usgs.gov/blog/nhd-viz-d…

TopoRivBlender – Create custom 3D images of topography and hydrography with our new Water Data blog! waterdata.usgs.gov/blog/topo-riv-… #reproducibility #WaterData #Python #Blender #Cartography

Happy Labor Day from USGS Water! From our hydrologists in the field to the back-end developers delivering our data, we celebrate all of our #USGS Water employees! #LaborDay

For water lovers, it's #GreatAmericanOutdoorsDay, and all #NPS park entrance fees are waived. "Know the flow" before you go for a safe experience – waterdata.usgs.gov 📸 Share your photos with us! #YourPublicLands #FindYourPark

#Groundwater is one of our most valuable resources, and @USGS Water serves data on groundwater levels from nearly 1 million monitoring locations across the U.S.!

@USGS recently released the National Water Availability Assessment, providing an overview of water availability that offers first-of-its-kind insights into the balance between water supply & demand across the conterminous U.S. 💧 Check it out 👉 ow.ly/kZPW50UMCB9

Today, the USGS released the National Water Availability Assessment, which integrates info on water quality, quantity and use to provide a comprehensive view of water availability. Visit the Key Findings Interactive Website to learn more: water.usgs.gov/vizlab/water-a…

Do you use the dataRetrieval #rstats package? If so, consider joining us for usability testing. Your input will help shape the future of the package as we update functionality to serve USGS water data from new APIs. Interested? Email comptools@usgs.gov

December brought less snow cover than usual in many parts of the contiguous U.S. ❄️ #DataViz #rstats Data from @NSIDC nsidc.org/data/mod10cm/v…

Join us on Thursday, Jan 16th for the release of the National Water Availability Assessment, a pioneering scientific overview of water availability across the conterminous US. Register for event here: ow.ly/4uI450UuEU2

🚨 NEW BLOG ALERT #rstats! Flex those #tidyr skills and improve your functions with helpful dataframe evaluation patterns! #MustRead for #DataScience with this next post in the #WaterDataForTheNation #Blog series. waterdata.usgs.gov/blog/rds-funct…

Learn to write more concise, efficient, and robust #rstats code in the next #WDFN #blog post. We focus on the map_*() family of functions from the #tidyverse #purrr package to move away from copy/paste coding to save you time and grief. waterdata.usgs.gov/blog/rds-itera…

Looking to fold @uscensusbureau data into your workflows? Our latest blog shows how to use #tidycensus to explore & visualize social vulnerability indicators in the Western U.S., with #reproducible code! 🔗: waterdata.usgs.gov/blog/acs-maps/ #rstats #DataViz #WaterInsecurity #OpenScience

This November is off to a rocky (as in not-snowy) start to the winter! Most of the Great Plains and Midwest saw less snow cover than usual ❄️ #DataViz #rstats Data from @NSIDC nsidc.org/data/mod10cm/v…

The R.A.D. Framework leverages three equally important approaches for decision-making when managing changing systems: Resist, Accept, and Direct. #ClimateResiliency #WaterScienceWednesday View the DataViz➡️labs.waterdata.usgs.gov/visualizations…

So excited to share our latest website! Unique data-storytelling style, fun #scicom approach, and with illustrations made by a former intern and myself.
