Oklahoma City reservoir levels are at 57.4 percent of full this week.
That's up 1.5 percent from last week, thanks to rains filling Lake Atoka and McGee Creek Reservoir in southeast Oklahoma, said Marsha Slaughter, the city's utilities director.
Water was being released Thursday from McGee Creek, while Canton Lake 100 miles northwest of Oklahoma City was only 20 percent full.
The city drew water from Canton during the winter to replenish Lake Hefner, which had dropped to historic lows because of drought. Lake Hefner is essentially full.
Odd-even water conservation measures remain in effect in Oklahoma City; further restrictions on outdoor watering will kick in if reservoir levels drop to 50 percent of full.
Drought conditions prevail across 68 percent of Oklahoma this week, unchanged from last week. Western Oklahoma remains in the worst shape.
