PLANO — Some of North Texas' largest cities may go back to once-a-week watering as early as Sunday.
Most member cities in the North Texas Municipal Water District are under Stage 3 enhanced restrictions. That means customers can only water once every other week.
City managers from Plano, McKinney, Frisco, Allen, Richardson and Mesquite told district officials they plan on returning to Stage 3 restrictions on Sunday. That means residents can water once a week.
"This doesn't mean water, water, water," said Plano City Manager Bruce Glasscock. "We will still monitor our usage."
The U.S. Army Corps of Engineers has started slowly releasing water from Lake Lavon, which is up more than a foot over its normal level.
Glasscock wants customers to understand the restrictions are no longer about Lavon, but Lake Texoma, where zebra mussels forced a halt to access of 28 percent of the district's water supply.
"People see all this rain, and they see all the lakes full, and say, 'Why don't you lift the restrictions? Let us water,'" Glasscock said. "It's a capacity issue. It goes back to the ability to provide water down the road, in the future."
The water district board of directors has called an emergency meeting for Thursday afternoon to discuss easing restrictions.
