New Brunswick Water Restrictions 2026
Published: · Updated:
By Daniel Roy · Central & Atlantic Canada Editor
Neither Saint John nor Moncton has mandatory watering restrictions. Both have asked for voluntary conservation in past dry spells — Saint John in September 2025, when Loch Lomond was down about a metre — and both manage water quality as actively as quantity, with Moncton adding precautionary treatment for cyanobacteria in the Turtle Creek watershed.
No mandatory municipal restrictions in Saint John or Moncton — Loch Lomond and Turtle Creek reservoirs both held adequate storage through the 2026 season.
Conditions are tracked by the Canadian Drought Monitor (AAFC).
Neither Saint John nor Moncton has mandatory restrictions
New Brunswick's two largest cities impose no assigned watering days and no permitted hours. Both have asked for voluntary conservation when conditions warranted, and both lifted the request when they eased.
Two different constraints
| City | Supply | The actual issue |
|---|---|---|
| Saint John | Loch Lomond and Latimer Lake, in a provincially designated protected watershed | Reservoir drawdown — levels fell about a metre in September 2025, prompting a voluntary request |
| Moncton | Turtle Creek and Tower Road reservoirs, roughly 17 billion litres | Water quality — cyanobacteria in the Turtle Creek watershed, first found in 2017 |
Moncton's storage relative to its population is unusually favourable, which is why it held off on restrictions in August 2025 while other New Brunswick communities imposed them.
Quality, not quantity
New Brunswick illustrates a pattern that runs through eastern Canada: the binding constraint is generally in the machinery between the source and the tap, not in the source.
Saint John rebuilt its water system through the Safe Clean Drinking Water Project, in service from 2018, because the water it had needed better treatment — not because it was running short. Moncton's recurring concern is blue-green algae, which is driven by warm still water, sunlight and nutrient loading rather than by reservoir volume. A full reservoir can have a bloom.
Watershed protection as land-use policy
The Loch Lomond watershed is designated under New Brunswick's Watershed Protected Area Designation Order, which regulates development and activity on the land draining into the reservoirs. It is a different model from a city protecting water by placing its intake kilometres offshore: here, source protection is a question of what may happen on the ground.
