Stage III
From the city:
I'll have some thoughts in the morning, but on first glance, this seems quite reasonable.
While full lakes and lower water use offer some degree of comfort to relax restrictions from the previous Stage IV Severe Mandatory Conservation, City Manager Patrick Baker said it is important that the City set clear triggers that will move the City to tighten restrictions again. “Since our stream flows are still lower than normal and higher usage months are right around the corner, we need to be cautious about rolling back restrictions, and clear about when we will not hesitate to tighten them again,” he said.
“Given our experience last year, there’s a new normal for the City. For that reason, our future triggers for tightening restrictions, if necessary, over the summer months of May through September when water use is at its highest, will put us well ahead of where we were with comparable lake capacities during the same period last year,” Baker said.
Triggers, which will be based on premium water supply (water above the intakes) in City lakes, are as follows:
* If capacity remains above 80 percent, the City will restrict outdoor watering to two days per week, Stage III. (Compared to last year, capacity had fallen to 40 percent when the City moved to Stage III in September.)
* When capacity falls to 80 percent, the City will restrict outdoor watering to one day per week, a modified version of Stage III. (Compared to last year, capacity was at 27 percent when the City restricted watering to one day per week in October.)
* When capacity falls to 50 percent, the City will not allow outdoor watering, and will move to Stage IV Severe Mandatory Conservation. (Compared to last year, capacity was at 14 percent when the City moved to Stage IV in December.)
Baker said that there is still a need to ensure that the citizens make conservation a lifestyle change. “As we move forward, we still need our customers to make water efficiency a year-round habit and continue to conserve wherever they can,” he said. “With ongoing conservation and these restriction triggers in place, Durham will be much better prepared to withstand another record drought should that occur this summer.”
Stage III Restrictions allow Durham customers to water outdoor landscapes on Wednesdays and Saturdays ONLY, either between 5 a.m. and 8 a.m. OR 5 p.m. and 8 p.m. Customers may only water during ONE of the allowed times each Wednesday and Saturday, and should be careful to avoid excessive run-off or water waste.
Additional Stage III Restrictions include:
· City water may not be used to wash down outside areas such as sidewalks, patios or driveways, except where a health or safety issue may exist.
· City water may not be served at a restaurant except upon request by the customer.
· City water may not be used to wash the exterior of a motor vehicle except where a private well system is used, or where 50 percent or more of the water is recycled or where it can be demonstrated that 30 gallons of water or less are used to wash the vehicle.
· City water may not be added into a decorative fountain, pool, or pond except where the water is recycled.
Athletic turf is eligible for special consideration within the modified Stage III Mandatory Conservation Measures since athletic fields must be maintained in order to ensure player safety. Institutions that use athletic turf, along with other industrial, manufacturing and commercial customers, may apply for a written license from the city manager to use water contrary to the modified Stage III restrictions if they can demonstrate a reduction in usage of 30 percent or more. Special consideration may also be given for one-time draining, refilling, maintenance, and cleaning activities for both community and private pools. Licenses will not be granted for installation of new sod or other water-intensive landscaping.

Are Stage 3 restrictions now permanent? The City has explained the trigger for returning to Stage 3.5, and Stage 4, but what about Stage 2?
Even Falls Lake has risen back above 250 feet now and continues to rise steadily due to this week's rain.

The press release doesn't mention what it would take to ease Stage III restrictions, but one clue is here:
Since our stream flows are still lower than normal and higher usage months are right around the corner . . .
You can monitor stream flows into our reservoirs here, for Lake Michie, and here, for Little River. On the graph that measures discharge, the triangle represents the median stream flow as recorded over the past X years. (I think it's 85 years for lake Michie and 20 some years for Little River.) If stream flows start staying at or above the median, even in a period of, say, a week to 10 days without rain, then we can start to think that the ground water situation is returning to normal, and start considering dropping to Stage II.
That's just an assumption on my part, but i think it's well grounded.
