ALT (Left) Chart of national streamflow conditions by flow percentiles at USGS streamgages relative to the historic record. In October, about 25% of states had wetter than average streamflow conditions, and about 30% had drier than average. (Right) Streamflow conditions in the U.S. with a tile chart for each state. Tiles HI, AK, UT, CO, AZ, NM, IA, IN, OH, WV, VA, PA, NJ, CT, MD, RI, FL show wetter than normal conditions, and states such as WA, ID, OR, VT, NH, ME, AR, TN, LA, MS, PR showed drier.
ALT A green weathered USGS gaging station sits along a rocky, moss-covered bank overlooking a fast-flowing river with visible rapids. The river flows through a dense forest with scattered patches of snow on the opposite bank. Text reads A new way to measure flow: video-based streamflow measurements .
ALT A two-panel image showing a river cross-section measurement. Text on top says: From video-capture to cross-section data, new tool helps measure streamflow from the safety of the river edge Top panel: A photograph of a rushing stream with rocky, snow-dusted banks. A bright yellow diagonal line is superimposed across the water channel, connecting two red markers on opposite banks to indicate a measurement transect line. Small white numbered markers are visible on the banks. Bottom panel: A line graph plotting the stream's cross-section profile. A white line with blue dots plots the riverbed depth, showing a maximum depth of approximately -0.43 meters below water level. A horizontal dashed yellow line represents the water stage level, corresponding with the yellow line from the top panel.

ALT A USGS hydrograph displaying discharge at Neches River Saltwater Barrier at Beaumont Texas in August 2020 during Hurricane Laura. A blue line peaks sharply around 12,000 cubic feet per second, then drops sharply below zero to negative 7,670 cubic feet per second. A large black arrow points to the lowest valley of the curve, labeled with bold text reading "Flow reversal." Background photo shows a muddy river and green trees.
ALT Closeup photo of Blood Falls at Taylor Glacier in Antarctica. A bright reddish-orange plume of water flowing into an ice-covered body of water from the glacier contrasts with the bright white ice pack and the rocky shoreline.
ALT A USGS hydrologist wearing a bright yellow jacket and orange life vest paddles an orange inflatable kayak down a calm river while towing an orange Acoustic Doppler Current Profiler to measure streamflow. Trees with yellow and orange foliage line the riverbank under an overcast sky.

ALT Map of domesticself-supplied water use by watershed. Areas of dark purple are shown where watersheds have higher water use, such as the Northeastern U.S., California, coastal Washington, and much of the eastern U.S. Below that is a time series showing water use every 5 years from 1985 to 2020, water use has increased from the lowest value in 2015 to the highest value in 2020.

ALT Two USGS scientists sit by three coolers near a creek. One scientist is looking at a vial while the other scientist is labeling a vial.
ALT A scenic mountain lake lined with pine trees with text that shows the definition of “HUC,” pronounced huck, acronym standing for Hydrologic Unit Codes. HUC is a number used to identify different drainage areas. Each HUC represents a specific watershed or basin at a particular scale.
