The Carouge basin is the point of convergence of the Orge, Blutin, Salmouille and Boële. The basin was dug in the 1970s to extract materials for road construction, and also to manage the floods of the Orge. Here you can see many species of birds, such as seagulls, cormorants and ringed plovers depending on the season. The path along the basin is safe and flat.

After having traveled about twenty kilometers along the barley starting from Morsang sur orge, this lake offered us a magnificent landscape, hidden between the trees. It was difficult to leave this place to come back home!

This water park is only the culmination of the Ollainville water treatment plant known as the Moulin Neuf, on a former industrial site that had been cleaned up and rehabilitated which had replaced the old mill. The site is next to the Syndicat de l'Orge, de la Rémarde et de la Prédecelle, which does everything in its power to ensure that the paths and routes in the Barley basin are practicable and maintained.

It is one of the many Orge retention basins between Breuillet (Port Sud basin), Egly (Trévoix mill basin), Brétigny (Petit Paris and Carouge basins) and Longpont-sur-Orge (Parc de Lormoy) and beyond. These pools, very well maintained and offering exceptional flora and fauna, make it possible to make loops of more than twenty kilometers quite easily (as long as one remains in the valley). A set of exotic and relaxing pools.
