USGS water data expert Garret Welsh measures water flow in the pouring rain at the Straight River near Faribault, Minnesota. This measurement recorded the 6th highest flow in the station's 59-year history, highlighting the severity of current flood conditions. Such data is crucial for emergency managers and forecasters to protect communities at risk.

This animation is the third video in a series explaining different aspects of the Phragmites Adaptive Management Framework (PAMF). This video focuses on the machine learning model that PAMF uses to systematically learn from participant's data and then provide site-specific management guidance in return.

Climate change is predicted to alter sport fish communities in Midwestern lakes, but managers currently have limited information on individual lakes that can be used to set local expectations or intervene with mitigation strategies.

Endocrine disrupting chemicals were identified in all of the 11 Minnesota lakes studied by the U.S. Geological Survey, St. Cloud State University and the Minnesota Pollution Control Agency. Female characteristics were observed in male fish in most of the lakes studied. USGS scientists Jeffrey Writer talks to us about what's going on.
