Falls Lake Is Dropping Again. So Why Can Raleigh Still Water Its Lawns?

If the shoreline at Falls Lake has been creeping outward all fall, and Durham households are still barred from running sprinklers on city water, why has Raleigh had no water restrictions since early August?
The lake's surface elevation is the figure you can see from the shore. The figure that sets Raleigh's watering rules is a percentage, and the threshold it gets measured against changes with the calendar. This fall the two have been moving in different ways, and the percentage is the one worth following.
This summer's low point came first. Then, as WRAL reported on July 28, a week of rain lifted Falls Lake more than two feet, to about 248.4 feet, roughly 3.1 feet under its 251.5-foot normal level. Labor Day felt like a recovery. Boaters lined up at the ramp, and one told ABC11 the water "look[s] great."
That recovery didn't hold. In mid-October, the U.S. Army Corps of Engineers' Wilmington District reported Falls Lake at 246.34 feet against a 251.50-foot guide curve. That puts the lake about five feet low and more than two feet below where it stood after the July rain. As of the NC Drought Management Advisory Council's Oct. 6 assessment, Wake, Durham and Granville counties were in D2, or severe, drought. WUNC reported on Oct. 8 that the first week of October brought little change in central North Carolina.
By the shoreline, then, conditions are worse than they were in August. Raleigh's watering rules have stayed the same anyway.
The city's Water Supply and Drought Status page splits Falls Lake in two. Raleigh can draw on about 58 percent of the lake's water, called the water supply pool. The rest is the water quality pool, held for releases downstream. The city states the distinction plainly:
"It is important to note that the overall lake level does not directly reflect the available drinking water supply. It is normal to see exposed shoreline in shallow areas during extended dry periods."
So the drinking-water reserve is the figure to follow, and recent readings show how quickly it is falling:
That is a 13-point drop in about five weeks, at a time of year when lawns and gardens are using less water than they did in July. Even so, Raleigh has no restrictions. The calendar explains why.
Raleigh's Water Shortage Response Plan ties each drought stage to the percentage left in the supply pool. It sets triggers month by month, using a model built on more than 100 years of Falls Lake flow data. The threshold rises and falls with the lake's natural fill-and-drawdown cycle. On the status page, the city listed 45 percent as the "Ending Trigger for September." At 71 percent, the supply pool sits well above that line.
ABC11's September story described 75 percent as the threshold that "previously triggered conservation measures." Because the triggers change by month, that figure applied to an earlier point on the calendar. It shouldn't be read as the line for late October.
Once a trigger is met, there isn't much slack in the plan. The city manager has to put the plan into effect within one week. City Council can start a stage early but can't delay one after its trigger is met. As written in the plan, Stage 1 for households looks like this:
During Stage 1, the city's water conservation stages page recommends no more than half an inch of landscape irrigation a week. Raleigh lifted Stage 1 on Aug. 3 and has asked residents to keep "using water wisely" since then.
The timing matters for lawns. NC State Extension's tall fescue calendar sets Piedmont overseeding for Sept. 1 to Oct. 1 and says to keep seedbeds moist with light watering several times a day. Fescue seeded this fall is now in the weeks when it needs water most, during a severe drought, while the supply pool keeps falling.
Durham runs a separate water system. It draws from Lake Michie, the Little River Reservoir, purchased Jordan Lake water and Teer Quarry, not from Falls Lake. Its Stage 2 Water Shortage Response took effect June 15. The city's Oct. 12 update confirmed it is still in place. Spray irrigation on city water is prohibited, vehicle washing is limited to compliant commercial or institutional car washes, and customers using more than 100,000 gallons a day are asked to cut use by 30 percent.
The drought is the same for both cities. The reservoirs and the trigger rules are not, so sprinkler rules can differ from one side of the county line to the other.
The more lasting change may come from City Hall. ABC11 reported on Sept. 15 that city council heard during a work session that residential customers account for 61 percent of Raleigh's water use. Council members also discussed bringing back alternate-day irrigation rules similar to Cary's. Raleigh Water Assistant Director Ed Buchan told the station the city had such rules before the 2007 drought. Council Member Jane Harrison said that if the city could "save residents money by putting off some of these other sources," she would support it.
The city is also designing a $37 million upgrade to the Lake Wheeler and Lake Benson dams. Raleigh Water Director Whit Wheeler said that work alone should add about 2.5 million gallons a day. In September, city officials said current forecasting shows water levels fully recovering this winter.
If council adopts alternate-day watering, it would apply in normal years too, not only when a drought trigger is met. That would change how sprinkler systems across North Raleigh are programmed far more than any single fall's lake level.
None of this has closed Falls Lake. The NC State Parks 2026 operating schedule lists the Beaverdam day-use swim beach and non-gas boat ramp, the Highway 50 boat ramp, and the Rolling View swim beach and boat ramp as open year-round. Sandling Beach's season ended Oct. 1.
Low water does change what's under the hull. Even after the late-summer rise, one boater told ABC11 there were "places six inches underwater." He described stumps and rocks that can tear up lower units and throw people from boats. That was in early September, when the lake was higher than it is now. Our July look at Falls Lake weekends covered the summer deficit, and the shallows have only grown since.
The lake's fall calendar is still running. Howl at the View is set for this Saturday, Oct. 24, from 5 to 7 p.m. at the Rolling View Community Building, 4201 Baptist Road in Durham, with trunk-or-treat, crafts and hiking.
