In this photo, USGS intern Brett Trottier (right) is learning how to prepare and deploy geophysical equipment from USGS hydrologist Eric White (left). The towed transient electromagnetic (tTEM) system is used to map the shallow subsurface to help us understand geologic and hydrogeologic conditions. In addition to the usual field safety procedures, Trottier and White are

This is an animation showing the changing conditions of USGS streamgages from April 1, 2020 to June 30, 2020. 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.
