Finding lakes and ponds for sale in Finistère takes patience: the department is rich in running water, but private ponds offered on their own are almost impossible to find. The large lakes of the Monts d’Arrée, such as the Saint-Michel reservoir or Lac du Drennec, are public reservoirs, and the coastal lagoons, around the Baie d’Audierne in particular, are protected. What actually reaches the market is mill ponds, small leisure ponds and longères (Breton long houses) sold with a pond, from Cornouaille to the Léon. The lakes and ponds for sale across France help widen the comparison; this page gathers the Finistère properties listed by private sellers, agents and notaires.
The panel that follows this introduction sets out recorded pond prices, for the department where sales allow and for Brittany as a whole. Then come the points that matter to a buyer in Finistère: salmon rivers and watercourse classification, closed or open water status, and looking after a pond on granite. The main stages of a purchase, from viewing to signing, are covered in our guide dedicated 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, only 2 pond sales were recorded in Finistère between July 2020 and December 2025: too few to publish a departmental 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.

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, 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.

Finistère’s largest stretches of fresh water never change hands. The Saint-Michel reservoir, created between the two world wars among the peat bogs of the Yeun Elez to regulate the Elez for a hydroelectric plant, lies within the Armorique regional nature park (Parc naturel régional d’Armorique); anglers fish it for pike, perch and trout. Lac du Drennec, a reservoir on the Élorn between Commana and Sizun, supplies drinking water to the north of the department and the Brest conurbation. At Huelgoat, the lake beside the state forest is a former water store for the Locmaria-Berrien mines and still feeds the Moulin du Chaos.
On the coast, the lagoons behind the dunes are first and foremost nature sites. The Étang de Trunvel, between Tréogat and Tréguennec, is cut off from the sea by a shingle bank; its reed beds, protected by the Conservatoire du littoral (the national coastal trust), host large numbers of migrating birds every year. Inland, Rosporden grew up beside a stretch of water on the Aven, long held back by a mill dam and then split in the second half of the 19th century by railway embankments. That model, the mill pond, accounts for most of the rare private sales.
Ponds sold without buildings are virtually non-existent in Finistère: in a landscape of small farms, hedgerows and steep-sided valleys, a pond nearly always comes with a house. Listings tend to describe a restored mill with its leat and millpond, a Cornouaille long house with a pond dug below it, or an old Léon farmhouse whose watering hole has been enlarged. These properties attract buyers looking for a main or second home, retirees returning to the area and anglers who want a private pond for carp or rainbow trout. As local supply is so thin, compare with the ponds on the market in Ille-et-Vilaine, the Breton department where most change hands.
Finistère is salmon and trout country: the Aulne, the Élorn, the Ellé and the Odet hold Atlantic salmon, sea trout and eels, and most watercourses are classed as first-category (salmonid) fisheries. A pond connected to one of them falls under open-water fishing rules, with their seasons, minimum sizes and the requirement for anglers to join an approved fishing association; only closed water, where fish cannot pass naturally, leaves the owner free to manage the fishing. Classification of the watercourse for ecological continuity can also require a mill’s dam to be fitted with a fish pass or managed differently. In communes covered by the coastal protection law (loi Littoral), building around a pond is tightly restricted, and in the Armorique regional park the park charter also shapes local planning documents. A fishing hut or an extension should therefore never be planned without first reading the local plan (plan local d’urbanisme).
On granite and schist bedrock the water is naturally acidic and low in minerals: fish grow more slowly than in a lowland pond on limestone, and careful liming is sometimes carried out. Mill dams, often stone-built, need their masonry, sluice gates and tailrace inspected; a seized gate makes draining impossible. The oceanic climate limits summer drying-out, but winter rain puts the spillway to the test. Ask the seller about invasive plants such as water primrose or Brazilian waterweed, and about coypu damage to the banks; our article on caring for a pond helps you put a figure on this work.
The few Finistère ponds offered on ma-propriete.fr come from private sellers, agents and notaires’ offices; on such a narrow market, an e-mail alert tells you about each new listing as soon as it goes live, and the filters let you keep only properties with a house. Owners can list their property too.
