U.S. River Conditions From October to December 2019
This is an animation showing the changing conditions of USGS streamgages from October 1, 2019 to December 31, 2019. The conditions shown range from the driest condition seen at a gage (red open circles) to the wettest (blue closed circles). There is also a purple ring added to indicate gages that are flooding.

A USGS guide for finding and interpreting high-water marks (AD)
High-water marks provide valuable data for understanding recent and historical flood events. The proper collection and recording of high-water mark data from perishable and preserved evidence informs flood assessments, research, and water resource management.

Understanding Floods | Long-term Streamflow Data Collection (AD)
The USGS is developing methods to improve data collection during floods to gain new insight into the rise and fall of flood waters. In the past, the only data left behind after a flood was how high the water got, or the peak of the flood.
