Re: Lake Hefner at record low water levels, when will city buy Canton water?. We're not talking about California. And believe me, long before you were ever there, tons of measures were taken to reduce household water consumption, including spending millions on incentives toward getting homeowners to switch to low-water yards and landscaping. And, of course, every bit of agriculture in California -- of which there is absolute tons -- is done through irrigation. California is in no way comparable to Oklahoma.
