Ardèche water level for canoeing: what you need to know before you set off

• The Ardèche rises in the Massif Central, at an altitude of 1,467 metres, near the Col de la Chavade, in the Mazan forest within the commune of Astet, and flows down to the Rhône through the gorges.
• After passing Aubenas and then Ruoms, the Ardèche is joined by several major tributaries such as the Chassezac and the Beaume.
• At Vallon-Pont-d'Arc, the river enters the famous gorges, carved over time by its own course, before ending its journey in the Rhône, near Pont-Saint-Esprit.
• Its flow is fed by three main sources:
  • Snowmelt from the Massif Central in spring, which explains the higher levels from April to June
  • Cévennes rain events, sometimes intense in autumn, which can cause rapid and unpredictable floods
  • Natural springs and groundwater, which maintain a minimum flow even during droughts
• What sets the Ardèche apart from other rivers in the south of France is its low-water support: a system managed by EDF that releases water stored in the Villefort, La Palisse and Le Gage dams and Lake Issarlès to maintain a minimum navigable flow even in the height of summer.
• The result: trips haven't been cancelled for lack of water in recent seasons, but a low level changes the experience, as we'll see below.

The official Tourist Office webcam

• The Gorges de l'Ardèche Pont-d'Arc Tourist Office provides a live webcam pointing at the river, viewable on the Tourist Office's official website.
• It's the simplest and most visual source: in a few seconds, you can see whether the river is low, normal or in flood.

• A calm green/blue river with visible sandbanks = low but navigable level.
• A river filling the whole bed, brown/ochre in colour with a visible current = high level; check with the operator before booking.

Vigicrues: real-time hydrological data

• The official Vigicrues website publishes real-time hydrological readings from the Vallon-Pont-d'Arc station.
• It shows the river's level, expressed in metres, along with a history that lets you track how the water level changes over several days.

• Below +0.50 m for the 7, 24 and 31 km trips, and below -0.30 m for the 12 km route, navigation is generally still permitted.
• Beyond certain thresholds set by prefectoral order, trips may be prohibited for safety reasons.

The operator: the most reliable day-to-day source

• A call or message to your operator on the morning itself is the most reliable method.
• The teams are out on the river every day and know the real conditions : not just the level, but also the clarity of the water and the state of the rapids and chutes.
• A normal reading on Vigicrues can sometimes hide cloudy or sediment-laden water after heavy local rain.

Low level: summer, dry spells (level below 0 m)

The trip is still possible, but the experience changes:

• Some rapids become more technical, the channels narrow and call for more precision in your line
• You can touch the bottom on certain shallow stretches, especially on the 12 km route between Sampzon and the base
• The sandbanks and natural beaches are more extensive: perfect for swimming breaks
• The water temperature is higher (22–26°C in July–August), which is lovely for swimming
• Paddling takes more effort on the flat sections, as the current is weaker

Ideal level: spring and autumn (level between 0 and +1 m)

This is the setup that regular paddlers prefer:

• The current naturally carries the canoe: less effort on the flat sections, a smoother rhythm
• The rapids are well formed, with a clear flow of water and readable lines
• The gorges are lush and the wildlife active: this is when you see the most birds
• The river is cooler (15–19°C), so a wetsuit is usually needed in April
• The 24 and 31 km trips are more enjoyable, as the current cuts down the paddling time

High level: after rain, floods (level above +1.5 m)

Counter-intuitively, a high level doesn't mean ideal conditions for beginners:

• The current becomes strong and fast: correcting your line is harder
• The rapids grow and become less readable: usually simple passages can turn serious
• Some natural beaches are submerged, and there are fewer places to stop
• The water is cloudy after run-off from rain: underwater visibility is nil
• Beyond a certain level, the prefecture can close the river to navigation

April

• High to moderate level, cool water (12–15°C)
• Wetsuit recommended
• Very good paddling conditions, quiet river
• Ideal for experienced paddlers

May

• Moderate to high level, water rising gradually (15–18°C)
• Ideal conditions for all levels
• Best time for the 24 and 31 km routes
• Numbers still reasonable

June

• Moderate level, pleasant water (18–22°C)
• Excellent conditions, lively river
• The transition between spring and summer
• The regulars' favourite time

July–August

• Low but stable level, warm water (22–26°C)
• Busy
• Perfect conditions for families and beginners
• Beaches at their largest
• More physical paddling on the flat sections

September

• Level rising again, water still warm (19–22°C)
• Numbers dropping noticeably
• Ideal conditions in every respect
• Our teams' favourite time of year

October

• Moderate to high level, cool water (14–17°C)
• Wetsuit advised
• Autumn colours on the cliffs
• The river almost deserted
• Sporty conditions

Can the Ardèche become completely unusable due to drought?

• No. The combination of regulating dams and the natural springs of the Massif Central guarantees a minimum flow throughout the season.
• In more than 20 years on the river, our team has never had to cancel a trip for lack of water.
• At a low level, the trip is more physical on the flat sections, but it isn't impossible.

What happens if the water level rises suddenly during our trip?

• Cévennes floods can be quick, but operators monitor weather and hydrological bulletins constantly.
• If a rise in the water is forecast during your slot, the departure is postponed or cancelled beforehand.
• On the water, evacuation points are spread along the route, and the instructors and teams know these exits and can bring groups ashore in the event of a sudden alert.

How do you read the level on Vigicrues : what does 0 metres actually mean?

• The 0 level corresponds to the gauge's reference point, not a dried-up river.
• It's a conventional zero set by the hydrological services.
• In practice, you can paddle without difficulty between -0.30 m and +1.50 m depending on the route.
• Above +2 m, the prefecture can restrict or prohibit navigation.
• Operators generally publish these thresholds on their website or share them directly on request.

Is September really better than July for a first family trip?

• In terms of comfort: September wins on almost every count.
• The water is still 19–22°C (pleasant for swimming), the river is far quieter than in the height of summer, the light is beautiful and the air stays pleasantly warm.
• The only advantage of July–August for families is the certainty of very warm water and a well-oiled organisation.
• For those with the flexibility, September remains our recommendation.

Our booking falls on a prefectoral closure day : what happens?

• If the prefecture decides to close the river, your trip is rebooked or refunded in full.
• No reputable operator goes ahead with a trip on a closed river.
• We let you know as soon as the decision is announced.
• For any practical questions, our FAQ page covers the most common situations.
