Field Photo Friday image for 6.3.22, USGS gage 02172020, on the Cooper River at Pimlico, SC.

A cartogram map of the US with proportional area charts for each state showing the proportion of streamgages by flow levels, categorized using percentile bins. Streamflow level percentiles are calculated using the historic daily record for each gage, and binned to reflect whether flow conditions are wetter or drier than the historical record.

Hi, I'm Salty, Drippy's saline counterpart! Did you know that one way to produce table salt is to evaporate saline water in evaporation ponds, a technique used by people for thousands of years?

USGS researchers collect surface water samples on the Animas River, New Mexico, June 2022

Bruce Bernard (left) and Scott McBride (right) obtain water and sediment samples at Egmont Key which is about 1 mile west of the mouth of Tampa Bay in the Gulf of America. Samples were collected June 14, 2010 prior to the possible occurrence of oil contamination from the Deepwater Horizon's oil well.

A cartogram map of the US with proportional area charts for each state showing the proportion of streamgages by flow level. Streamflow levels are shown as percentiles of the historic daily record at each gage, and binned to reflect whether flow conditions are wetter or drier than the historical record.

Here is the beautiful USGS gage 10317500, on the North Fork, of the Humbolt River near Halleck, Nevada, a bit Northwest from The East Humboldt Range and the Humboldt-Toiyabe National Forest. Water data back to 1913 are available online.  

When are U.S. rivers wet or dry? This circular area chart displays the total flow rate in million cubic feet per second throughout a year. Total flow is derived from 1,865 USGS NWIS gages with near complete data for 1951-2020.

The rise and fall of the Delaware River salt front. Over time, the location of the salt front moves in response to regional weather patterns, sea level rise, and human impacts. The precise location of the salt front in the Delaware River Basin is based on the location in the river where the average chloride concentration is 250 mg/L.

A time series of streamflow drought events occurring across 122 stream gages in the Upper Colorado River basin from 1980 to present. Periods of streamflow drought are indicated for each of 122 gages in a beeswarm-like chart, with time on the x-axis. During time periods where many gages experienced drought, the swarm bulges due to many co-occurring events.

A map of CONUS using angled wheat field vectors to compare lake growing degree days between the past (1981-1990) and present (2011-2020). The vectors are mapped to the number of growing degree days earlier or later on the x-axis, and the difference in temperature on the y-axis, resulting in vector angles spanning 360 degrees.
