OKLAHOMA CITY – Earlier this year, Lake Hefner was at extremely low levels.

Residents across Oklahoma City had been warned to conserve water during the drought.

After a brief bout of rain in April, Lake Hefner was still 11 feet below capacity

In May, heavy rain completely transformed the lake.

A recent report showed the lake to be 90 percent full.

At this time, residents are still encouraged to conserve water, which will be needed in the summer months.
