What does the inside of a groundwater well look like? This can be an important question for groundwater scientists! In this photo, we see the view from a video camera inside a groundwater well. USGS scientists can use cameras to inspect the inside of a well to identify any changes in the well that might affect groundwater level measurements over time.

A tile map of the US showing streamgages by flow levels through the month of September. For each state, an area chart shows the proportion of streamgages in wet, normal, or dry conditions. Streamflow conditions are quantified using percentiles comparing the past month’s slow levels to the historic daily record for each streamgage.
