Looking for lakes and ponds for sale in Côtes-d’Armor? Water is plentiful here, but ponds sold on their own are rare: on the granite and schist of the Argoat, inland Brittany, the dense web of streams was mostly dammed to drive mills, feed the Nantes–Brest canal or supply drinking water. What comes up for sale is therefore often a mill pond sold with the mill house, a leisure pond dug in a meadow, or land with a pond on the edge of woodland, from the Penthièvre to the Loudéac area. This page brings together the ponds and lakes for sale in the department, listed by private sellers, estate agents and notaires.
Straight after this introduction, a price panel shows what ponds actually fetch in the department and across Brittany. Further down you will find what sets the ponds of Côtes-d’Armor apart, who buys them, and the checks specific to a Breton water body: the mill’s water rights, the status of the stream and the condition of the dam. For the overall process, from the preliminary contract to the first draining, see our guide to buying a pond.
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, 17 pond sales were recorded in Côtes-d’Armor between July 2020 and December 2025, at a median price of €50,935/ha† and an average of €56,223/ha. This figure rests on 17 sales — too few for the average and median to reflect the department’s market faithfully, which is why they should be read alongside regional prices. With only 1 sale in 2025, the department does not allow a reliable annual price. In Brittany, 109 ponds sold over the same period at a median of €32,902/ha, and the regional median reached €26,201/ha in 2025† across 15 sales; the national median was €25,235/ha in 2025.

Prices are calculated over the whole area sold, water, dams and surroundings included: per hectare, small equipped ponds cost much more than large lakes. These statistics cover ponds without buildings; a house or an adjoining wood changes how the price is formed.
On the listings side, 26 properties with a pond are offered on ma-propriete.fr across France as of 2 October 2026, 2 of them in Brittany. Their median asking price is €94,000 for a median size of about 2.6 ha. These are advertised prices for whole properties, sometimes with a house or a pond, not recorded sale prices per hectare like those in the DVF database. Finally, remember the purchase costs, which you can estimate with our notary fee calculator.

The department’s ponds are above all a hydraulic legacy. The great lake at Jugon-les-Lacs, in the Arguenon valley, is now a well-known fishing venue; downstream, the Arguenon reservoir continues this chain of water bodies. In the centre, the Bosméléac lake, built in the 19th century on the upper Oust, used to feed the Nantes–Brest canal through the Hilvern channel, while at Glomel the Korong pond acts as the canal’s reservoir at its highest point. Lac de Guerlédan, held back by a dam on the Blavet, marks the border with Morbihan, where the ponds for sale in Morbihan form an equally thin market. None of these large lakes is for sale, but they sum up the nature of the market: ponds shaped by people and nearly always connected to a watercourse.
Alongside these public works, the private supply is made up of small units: former mill ponds whose dam has survived, farm ponds enlarged from cattle watering holes and turned over to fishing, and leisure ponds dug in a damp valley bottom. They mainly hold carp, tench, roach and pike; the streams that feed them are often home to brown trout and eels, which has a direct bearing on the legal status of the dam.
Sales of ponds without buildings are few, and most transactions cover a package: a longère (a traditional Breton long house) or a mill, a few hectares of meadow and woodland, and a pond. Local anglers want a fishing pond that is easy to keep an eye on, within reach of Saint-Brieuc, Dinan or Lannion. Another group, from other French regions or from abroad, the United Kingdom in particular, looks to central Brittany for a quiet house with a pond, away from the pricier coast. If the adjoining wood also appeals to you for game, the hunting properties in Côtes-d’Armor round off the search.
In a department where almost every pond touches a stream, legal status is the first question to settle. For a mill pond, ask for the documents that establish the water right: a mill “fondé en titre”, dating from before the French Revolution, keeps its legal capacity as long as its essential structures have not fallen into ruin, whereas a more recent pond must have been authorised or declared under French water law. Next, check how the watercourse is classified: if it is listed for ecological continuity, the authorities can require a fish pass, adapted sluice management or a bypass channel. Finally, the Loire-Bretagne river basin plan (SDAGE) bans new ponds in catchments that contain designated “biological reservoirs” and in areas already dense with ponds, so a lawful existing pond has a value that would be hard to recreate elsewhere. The valley bottoms and wet meadows around it are often listed in the commune’s wetland inventory, which restricts filling and drainage.
Many pond dams in Côtes-d’Armor are old, built of earth and dry stone. Have them checked for watertightness, for trees on the crest, whose roots open up leaks, and for a working sluice or “moine” (the monk outlet used to drain the pond). Coypu burrows weaken banks and dams, so ask the seller how they are kept in check. Silt builds up quickly in ponds fed by streams that drain arable land, and nutrient-rich water encourages algal blooms in summer, sometimes cyanobacteria. Before buying, find out when the pond was last drained, where dredged silt can be spread and what a flood spillway might cost; our article on routine pond maintenance covers each of these items.
Pond listings for Côtes-d’Armor on ma-propriete.fr are posted by owners, agents and notaires’ offices; filter them by price, by size or by whether a house is included, and switch on an alert to hear as soon as a new water body appears. Sellers can list their own property too. If the woodland around the pond matters as much as the water, browse the woods and forests for sale in Côtes-d’Armor; to compare with the rest of the peninsula, see ponds for sale across Brittany.
