The lake is well appreciated by fishermen for its large population of fish. Every season has its own charms, which attract the eye of many photographer. Relaxation and change of scenery guaranteed!

The dam and the Lake of Pannecière

After de big floods of the Seine river, like the one that struck Paris in 1910, it was decided to create dams in other to be able to regulate the water level of the Seine and its tributaries.  The construction on the barrage of Pannecière was started in 1939, and after being interrupted twice due to the 2nd World War it was finished in 1949.

The dam is built in the Yonne valley, where the granite provides the lake its watertight foundation. The dam is of the type: "à voûtes multiples et contreforts " (multiple vaults and buttresses), it has 13 vaults, is 49m high and has a length of 352m.

A hydro electric plant, exploited by the E.D.F. (a French energy provider), was put into use in 1950. Four departments (Paris, Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne) are grouped in a public institute called " Les Grands Lacs de Seine " which is responsible for the dam.
