One of America’s largest reservoirs just hit a record low

Filed by Dr. Vera Quark

Lake Powell has fallen to its lowest level on record after an exceptionally dry and warm winter left the Colorado River Basin with little mountain snow to melt. Lake Mead also reached record lows, raising concerns for a river system that supplies water and power to more than 40 million people. Federal officials have taken emergency steps to stabilize Lake Powell, including sending in water from another reservoir and reducing releases downstream.
