Lake Hefner at record low water levels, when will city buy Canton water?

[law]

261 days, assuming that the plant is putting out 100 million gallons per day and it's being used somewhere, and assuming zero water enters the lake. Neither of these things will happen.

As a point of reference, with only the water that went over the dam at Overholser this weekend, Lake Hefner could be filled by a third.

Are you calculating the entire volume of Lake Hefner?
