Millions of people are facing a threat to their water and electricity supply. A major reservoir in the US has reached a critically low level. This reservoir is important for many states, including several in the western US.

The low water level is causing concern about the management of a key river system. Several states rely on this river and are struggling to agree on a plan. Further information about this developing situation is available from KSAT 12, a local news source in San Antonio, TX.
