Officials in southwestern Oklahoma said the water level at Lake Waurika remains extremely low, even with the recent rain.
Water use restrictions will remain in place for a half dozen towns that draw drinking water from the lake.
The lake is currently 938 feet above sea level, seven feet lower than the previous low, which was recorded as 945 feet in October 2006. Its record high was 964 feet, which was recorded in June 2007.
Officials said it would take 3.5 inches of rain across the entire 562 square miles of the lake to fully fill the lake back up.
