France's most watery golf courses, and why hectares are the wrong unit

Water is the hazard that costs a stroke, not merely a bad lie. It is also the one most often mismeasured, because the first instinct is to count hectares — and in hectares the ranking is wrong.

Here are France's 3,646 traced water hazards, and the reason they have to be counted one at a time.

A third of France's water sits in twenty-three polygons

Twenty-three polygons exceed 10 hectares. On their own they carry 37.6% of all traced water surface in France.

They are not playing hazards. They are lakes, rivers and stretches of sea that the course runs alongside, traced because they border the land rather than because a ball can be lost in them.

Surface	Declared type	Course
164 ha	river	Club de golf d'Étretat
99 ha	stream	Golf de La Grande Motte
76 ha	river	Lac au Duc, Ploërmel
69 ha	river	Bluegreen l'Ailette
39 ha	lake	Golf de Spérone
32 ha	lake	Golf du Fort
28 ha	river	UGolf Albi Lasbordes
22 ha	lake	Domaine du Gouverneur

The first on that list is worth pausing over. Étretat's polygon covers 164 hectares and spans 1.8 km north to south, 2 km east to west. Its centroid sits west of the course — that is, offshore. The survey files it as a river.

It is the English Channel.

A ranking of France's wateriest courses built on surface would therefore put Étretat top of the country, for a body of water on which no ball has ever been played. That is why everything below counts zones, never square metres.

With those twenty-three giants removed, the median French water zone measures 1,087 m² — a pond thirty metres by thirty. The largest 10% exceed 7,900 m².

The ranking, by zone count

As with bunkers, a hazard count only holds on clubs where the number of holes surveyed is known: the 217 courses with a single 18-hole card and exactly 18 traced greens. The same rules apply — surveyed tracings only, type other excluded, polygon rather than point.

#	Zones	Water in play	Course
1	28	30,243 m²	Rougemont-le-Château, Territoire de Belfort
2	25	4,667 m²	Golf Hermitage, Grand Est
3	21	94,043 m²	Bordeaux Villenave d'Ornon
4	21	51,656 m²	Golf des Étangs, Auvergne-Rhône-Alpes
5	19	57,908 m²	Green Parc Illies, Hauts-de-France
6	19	14,544 m²	Vire la Dathée, Normandy
7	18	3,457 m²	Golf Du Rochat, Jura
8	18	7,143 m²	Golf Hippodrome, Occitanie
9	17	43,859 m²	Golf Saint Thomas, Hérault
10	17	202,302 m²	Rhuys Kerver, Morbihan

The median French course carries 6 water zones. Rougemont-le-Château lines up 28, more than one per hole and a half.

Compare the two columns again. Hermitage is 2nd by count with 4,667 m² of water; Rhuys Kerver is 10th with 202,302 m², forty-three times more. Two opposite ways of wetting a course: many small ponds, or a few large expanses.

And 47 courses hold none at all

Of the 574 French courses whose hazards are surveyed, 47 carry no water zone at all. Not a pond, not a ditch holding water.

They are mostly mountain and dry-ground courses, where water does not stay put and where natural drainage makes a decorative pond expensive to maintain.

Water, unlike sand, does make difficulty

Our most bunkered courses ranking ended on a null result: sand has no relationship with rated difficulty, r = −0.006. Water does.

Water zones	Courses	Average slope
1 to 4	33	129.4
5 to 9	28	133.3
10 or more	29	134.3

The correlation is r = 0.268. Weak, but positive and consistent where sand's was nothing. Five slope points separate the driest courses from the wettest.

The explanation lies in the nature of the penalty. A bunker costs a good player half a stroke and an amateur a stroke and a half — the gap between them stays moderate. Water costs a penalty stroke plus the distance, to everyone, and an amateur finds it far more often. That is precisely what slope measures: the gap between the bogey golfer and the scratch golfer.

Caution is still warranted: this comparison rests on 92 courses, those in the clean subset that also carry an identified men's back tee.

Lakes, streams and rivers

Type	Zones	Share
Pond or lake	2,363	64.8%
Stream	1,190	32.6%
River	93	2.6%

Two thirds of France's water is a standing body — a dug pond, a pool, an artificial lake. The stream, which crosses the ground without having been asked for, accounts for a third. Rivers are rare, and it is in that category that most of the giants in the first table sit, the Channel included.

Method

Source: the FlyAway production database, 17 August 2026. Hazards drawn from the surveyed tracings, not archived, type water, excluding community contributions and manual additions — 3,646 zones across 527 courses.

The ranking covers the 217 courses with a single 18-hole card that is not a doubled nine, carries a par of 68 or more and holds exactly 18 traced greens, for the reason set out in our bunker article: hazards being surveyed per club, a multi-loop club would count its zones more than once.

The surfaces quoted systematically exclude polygons above 100,000 m². The "water in play" column is therefore a figure net of those giants, and the raw national total is never published as such.

Every course named has its own page in the French course directory.
