A round of thunderstorms that flooded roads and low-lying areas in Oklahoma City over the holiday weekend did little to improve the city’s available water supply.
Oklahoma City’s six reservoirs rose by only a few inches, city spokeswoman Kristy Yager said.
The city’s available water supply was at 58 percent Wednesday, Yager said. City residents are under mandatory, permanent watering restrictions, and more severe restrictions would take effect if the available water level dips below 50 percent.
Lake Hefner, which stood at 7.9 feet below normal Tuesday afternoon, rose by only about 8 inches after the weekend’s rain, Yager said.
“We need far more rain,” she said.
Areas in the Oklahoma City metro received a little more than 2.5 inches of rain between Friday afternoon and Tuesday afternoon, according to the Oklahoma Mesonet weather network.
The weekend’s showers were spread out over several days, meaning the rainfall mostly soaked into the ground rather than running off into streams and tributaries that eventually flow into city reservoirs, Yager said.
Water levels at 2 p.m. Tuesday
Lake Hefner: 7.9 feet below normal
Lake Stanley Draper: 3 feet below normal
Lake Overholser: 4.5 feet below normal
Lake Atoka: 8.5 feet below normal
Canton Lake: 12.6 feet below normal
McGee Creek Reservoir: normal
