U.S. River Conditions from January 1, 2023 to March 31, 2023 at @USGS #streamgages 💧 

River conditions range from driest conditions at a gage (red open circles) to the wettest (blue closed circles). A purple outer ring indicates flooding. 

Animated map of the continental U.S. and paired line chart. For each month from 2000 to 2020, the map shows burned areas within water supply watersheds, and the chart displays the total number of affected water users. In 2003, 2005, 2014, and 2017, wildfires burned key water supply watersheds that together supply water to over 1.5 million consumers.

Mean daily streamflow (cfs) of the Rio Grande at Embudo, New Mexico from 1991 to 2022. The chart has a black background and the 30 years of mean daily streamflow data are plotted as stacked white ridge lines that emulate the aesthetics of a classic rock album.

Circularity of named lakes in the U.S. A histogram shows circularity for lakes and reservoirs in the United States, defined as 4π * Area / perimeter squared. The distribution is skewed left, as most lakes and reservoirs aren’t very circular.

The USGS is monitoring streamflow and water-quality in burned watersheds across the western U.S.

East Troublesome burned area, Colorado, two years post-fire. Compared to the other photo, it is a bit more lush with grasses growing. Many trees are distinctly still black and have no foliage.

A Tale of two winters. A map of CONUS and lollipop style charts show the difference in percent snow covered area for February 2023 compared to the 20-year mean (2003-2022). Paired charts show the relationships between latitude, longitude, and difference in percent snow covered area, depicting two very different winters between the coasts.

8 maps of the continental U.S. show county-level water use for 8 categories of use – thermoelectric, irrigation, public supply, industrial, aquaculture, mining, domestic, and livestock. Use in each category is shown as a percent of total water use, by county. In the northern plains, most water is used for livestock. In west Texas, most water is used for mining.

A 3D aerial view of Norristown, Pennsylvania shows where the Schuylkill River passes through the city. The water in the river is shown in bright blue, while the surrounding city is shown in natural color.

An alluvial diagram showing the number of deaths due to natural disasters in the United States over the past 50 years (1972 – 2022). The data include deaths due to eight types of natural disasters: wildfires, drought, extreme temperatures, landslides, volcanic activity, earthquakes, storms, and floods

A data visualization showing how Minimum Annual Streamflow has changed from generation to generation over the past 100 years. Across the contiguous United States, streamflow has increased by 22% when comparing the baseline “Silent generation” (1920 – 1946) against the Gen Z years (1997-2020).

A tile map of the US showing streamgages by flow levels through the month of March 2023. For each state, an area chart shows the proportion of streamgages in wet, normal, or dry conditions. Streamflow conditions are quantified using percentiles comparing the past month’s flow levels to the historic record for each streamgage.

Six panel data visualization in the graphical form of a comic. The first panel is of a bright sun with trees lining a street that has tall buildings on either side.

An animation of spring leaf out timing in the contiguous U.S. from Jan 1 2023 to Apr 3, 2023. A map and bar chart are synchronized to show the onset of spring as the year progresses, with southernmost parts of the U.S. first entering spring and rising up through parts of the midwest and east coast.

Waffle charts are colorized and faceted by contaminant (Pb, Fe, NO3-, and Sr) and region (West, Central, Midwest, East). Each 10 x 10 waffle charts shows the proportion of study area that contains high, moderate, and low concentrations where 1 square = 1 % of region. Figure contains callouts where, for example, NO3- in the Central U.S.

In 2015, water use in the U.S. totaled 322 billion gallons/day. Total water use is broken out into 8 categories using different colors.
