This is an animation showing the changing conditions of USGS streamgages for Water Year 2018 (October 1, 2017 to September 30, 2018). The conditions shown range from the driest condition seen at a gage to the wettest. There is also an indicator for gages that are flooding, but it is noted that both USGS gage height and National Weather Service flood stage levels are

USGS scientists and technicians took water measurements during flooding on the Big Sioux River near Jefferson, SD in March 2019. Measurements for this site were 52,000 cfs at a gage height of 40.14 ft. More information about this USGS streamgage is available at https://waterdata.usgs.gov/sd/nwis/uv?site_no=

You may know that groundwater serves many purposes worldwide. Of course, drinking water and domestic uses of water are a major component of those uses. The ways of getting at groundwater differ depending on the local underground conditions. Water may be plentiful just 10 feet below the land surface, or a deep well might have to be drilled many hundreds of feet to get at

The most common method used by the USGS for measuring velocity is with a current meter. However, a variety of advanced equipment can also be used to sense stage and measure streamflow. In the simplest method, a current meter turns with the flow of the river or stream. The current meter is used to measure water

Who's who?  These are print casts of front and back paw prints of a grizzly bear (top) and black bear (bottom). The casts on the right are the front paws of each species; the casts on the left are the back.  How do you tell? 

Grizzly/brown bear toes are closer together and form a fairly straight line above the paw pad. On a black bear, the toes are further apart and
