Privately owned lakes and ponds for sale in Île-de-France are rare, and it is better to know that before you start. The region’s largest water bodies are public: royal ponds built to feed the fountains of Versailles, lakes in leisure parks created from old gravel pits, ponds in state forests. The private market is concentrated in the outer ring of departments, above all Seine-et-Marne, and seldom takes the form of a pond sold on its own: a mill with its leat, a Brie property with an ornamental pond, a house with a pond on the edge of a forest, a former extraction pit converted to fishing. In the inner ring around Paris there is practically no private pond to buy. Available properties, put up for sale by owners, agents or notaires, join our nationwide selection of ponds and lakes for sale, also useful for widening your search to neighbouring regions.
In the price block below, benchmarks remain fragile, since few ponds without buildings change hands here, and almost all of them in Seine-et-Marne. You will then find an overview of water bodies department by department, followed by the checks specific to a heavily urbanised region: the industrial past of gravel pits, flood zones, pre-emption of natural areas and protected sites. Our practical guide to acquiring a pond completes this advice.
According to the ma-propriete.fr pond price observatory, which keeps only ponds, lakes and pools sold without buildings in the French DVF land registry data, 15 ponds were sold in Île-de-France between July 2020 and December 2025, at a median price of €21,875/ha† and an average of €25,065/ha, or about €2.19 per square metre at the median. The region sits below the national median for the period (€25,694/ha). With 1 sale in 2025, no regional annual price can be published: the full period remains the benchmark.
| Department | Sales 2020-2025 | Median price | Average price |
|---|---|---|---|
| Seine-et-Marne (77) | 10 | €17,955/ha† | €18,497/ha† |
| Essonne (91) | 4 | not published | not published |
| Yvelines (78) | 1 | not published | not published |
| Val-d’Oise (95) | 0 | not published | not published |
| Île-de-France | 15 | €21,875/ha† | €25,065/ha† |
| France | 2,053 | €25,694/ha | €32,291/ha |
In 2 departments, the price rests on 10 to 29 sales: the sample is too small for these average and median prices to be truly representative of the local market, and the regional price remains the soundest benchmark; in 3 others, fewer than 10 sales do not allow a price to be published. Measured against the total area, banks included, a pond’s value depends heavily on its size: small, well-equipped ponds cost more per hectare. The figures concern ponds sold on their own, without a house or a large wood.
On the listings side, 26 properties with a pond are offered on ma-propriete.fr across France as of 2 October 2026, 1 of them in Île-de-France. Their median asking price is €94,000 for a median size of about 2.6 ha. These asking prices apply to complete properties, often with buildings, a pond or hunting rights: they cannot be compared directly with DVF medians per hectare. Finally, remember the purchase costs, which you can estimate with our notary fee calculator.

The region’s largest department accounts for most of the supply. In the Bassée, upstream of Montereau, and in the meanders of the Marne, aggregate extraction for the Paris building trade has dug strings of lakes; some, back in private hands, sell as a fishing pond or as wildfowling ground. On the Brie plateau, ponds sit in the woods, as in the state-owned Villefermoy forest, or in château grounds, while the Fontainebleau forest and the Gâtinais mainly have small pools. The valleys of the Grand and Petit Morin add mills with their leats. Details are on our page of gravel pits and ponds in Seine-et-Marne.
Yvelines owes its large ponds to the water network built under Louis XIV to feed the fountains of Versailles. The Étangs de Hollande, between Le Perray-en-Yvelines and Les Bréviaires, and the Étang de Saint-Quentin, at Trappes and Montigny-le-Bretonneux, are its centrepieces; a joint syndicate manages much of this system of ponds and channels (rigoles), part of which is now a national nature reserve, the réserve naturelle nationale des étangs et rigoles d’Yveline. In the Rambouillet forest as in the upper Chevreuse valley, covered by a regional natural park, smaller ponds dot the valleys, as at the Vaux de Cernay. Private properties are mills, houses with an ornamental pond or ponds in woodland, and they rarely come up: see our water bodies for sale in Yvelines.
In Essonne, the Saclay plateau keeps two ponds laid out in the 17th century to supply the lower parts of the Versailles park; the Étang Vieux is now a bird reserve. Further south, the Essonne and Juine valleys hold peat marshes, a habitat rare in the Paris basin: the special protection area of the Itteville and Fontenay-le-Vicomte marshes, one of the department’s largest wetlands, is largely owned by the department as a sensitive natural area. To the south-east, the Gâtinais français, whose regional natural park extends into Seine-et-Marne, completes this landscape of wet valleys and pools. Private listings concern valley ponds and mills; see our ponds and marshland for sale in Essonne.
Val-d’Oise has few private ponds. Its best-known water, the Lac d’Enghien, is a medieval pond created by the local lord for fish and his mills, which became the heart of a spa town. In the Vexin français regional natural park, water takes the form of mill leats, village ponds and ornamental ponds in château grounds, while a former sand quarry in the Oise valley has become the Cergy-Pontoise leisure park. The rare properties for sale are mills or houses with a small lake or pond.
In the inner ring, there is practically no private pond for sale. Water bodies belong to the State, the departments or the towns: the Ville-d’Avray ponds dear to Corot and the ponds of the Meudon state forest, such as Villebon and Trivaux, in Hauts-de-Seine; the lakes of the Georges-Valbon park, part of which lies in a Natura 2000 site, in Seine-Saint-Denis; the Lac de Créteil, a former quarry turned leisure centre, in Val-de-Marne. These sites matter for quality of life, not for the property market. A buyer who wants a pond close to Paris will turn to the outer departments and often beyond, to Oise, Eure or Loiret.
For a former gravel pit, request the prefect’s decision ending extraction and the official record that the site was restored, and have the stability of the banks and the nature of any backfill checked. The Seine, Marne, Oise and Loing valleys are covered by flood-risk prevention plans that restrict shelters, jetties and fences. A gravel pit that the river floods may be classed as open water, with the corresponding fishing rules: have this checked. As everywhere, the pond must be lawful under the Water Act, and any works project must remain compatible with the Seine-Normandie basin plan (SDAGE).
Land pressure and nature protection go hand in hand: where the department has drawn a pre-emption zone for sensitive natural areas, it can acquire the property instead of the buyer. Listed or registered sites, common around châteaux and in the valleys, make works subject to authorisation, and wetlands, Natura 2000 sites and nature reserves regulate dredging and alterations. Finally, in urban settings, shallow ponds are prone to cyanobacteria blooms in summer: ask the seller what they know about water quality.
Whenever a pond, a mill or a property with water is put up for sale in Île-de-France by a private seller, an agent or a notaire, the listing appears on ma-propriete.fr. As supply is very limited, an email alert ensures you do not miss the next one; sort properties by price or size, or list your own. If trees matter as much as water to your project, see our woodland and forest plots for sale in Île-de-France.
