Located at an altitude of 154 meters1, the pond covers an area of 0.8 hectares. The “Ponts-Quentin stream” flows into the Rompu pond — coming from the Holland ponds located about 1 km upstream to the east — and comes out to flow, about ten kilometers further to the west, in the Vesgre, having previously changed its name twice: first under the name of “Etang-Neuf stream” then under that of “Grapelin”. The Ponts-Quentin stream passes under departmental road 138 before flowing into the pond, which justifies the undulation of the road and its bend. The pond is part of the Rambouillet national forest, a private state domain. As such, its management is ensured by the National Forestry Office (ONF). Wikipedia
