Lake Folsom, California. Comparing drought and  non-drought conditions.
December 14, 2016
Drought in Folsom Lake, California —————————————————— The severity of California's current (2016) drought is illustrated in these images of Folsom Lake, a reservoir in Northern California located 25 miles (40 kilometers) northeast of Sacramento. The lake is formed by Folsom Dam, in the foreground, which is part of the U.S. Bureau of Reclamation's Central Valley Project. In the July 20, 2011 view...

Using an acoustic monitor (ADCP) to measure a flood on the French Broad River, Blantyre, NC
December 14, 2016
Acoustic Doppler Current Profiler ( ADCP ) to measure streamflow ————————————————————————————————— The use of acoustic Doppler current profilers (ADCPs) from a moving boat is now a commonly used method for measuring streamflow. The technology and methods for making ADCP-based discharge measurements are different from the technology and methods used to make traditional discharge measurements with...

Heavy rains from Hurricane Matthew, Oct 2016, causes record flooding on the Little River, Spring Lake, NC
October 10, 2016
This USGS streamgage sits on the Little River in Spring Lake, North Carolina, and has recorded two record flood events in the past two weeks. The most recent flooding this week (left) was brought on by heavy rains from Hurricane Matthew and the streamgage measured the flood waters at almost 32 feet.

Two men walk by debris along the side of the road
August 26, 2016
Daniel McCay and Chris Henry, U.S. Geological Survey hydrologic technicians, search a neighborhood south of Denham Springs, Louisiana, for high-water marks August 26. The term high-water mark refers to the debris flood waters will leave on walls, buildings and trees. This thin line of residue is an indicator of how high the waters reached, yet the fragile nature of these marks means they must be...

Chris Henry and Daniel McCay, USGS hydrologic technicians, use GPS equipment to survey a high-water mark outside of a flooded elementary school in Denham Springs, Louisiana, August 28. This school was located in one of the hardest hit flood areas and the blue line simulates how high the water was at its peak during this historic flood.
Two men mark a high-water mark on a structure
August 26, 2016
Daniel McCay and Chris Henry, USGS hydrologic technicians, use a level to draw a line on a high-water mark August 26. In most circumstances, when a high-water mark is flagged it would then be surveyed with GPS equipment to obtain its exact coordinates and elevation. However, because of the possibility of more storms hitting Louisiana the teams were initially only flagging marks at first, in order...
