As crops wither, power plants try to manage overloads, and rivers and streams dwindle to mere trickles, scientists at the U.S. Geological Survey are monitoring what could become this century’s worst drought. Such data is used by cities, counties, states and the federal government to plan for water shortages and to determine if similar problems can be avoided in the future.

Has the Potomac River been looking a little dry lately? Hydrologists -- i.e. water specialists--with the U.S. Geological Survey (USGS) will measure the potentially serious effects of the intense heat and lack of rain using a variety of instruments that you probably won’t find in your garage. USGS will measure water levels in the Potomac River -- Washington’s sole source of tap water.

All-time record low river flows into the Chesapeake Bay were recorded for May, according to hydrologists at the U.S. Geological Survey (USGS). Flow into the bay has been below average for the last 10 months. Average daily freshwater inflow to the Chesapeake Bay in May was about 29.1 billion gallons per day (bgd), which is about 46 percent of the long-term average (62.6 bgd).
