It belongs to the department of Isère. It is bounded by the canyons of the Drac and Ebron. The lake was created in 1961, when the 145-metre-high dam was built. The lake is 10 kilometres long; in some places it is up to 300 metres wide. This lake is often windy and wavy. It is considered to be one of the best places for windsurfing and kitesurfing in Europe. It is also an important site for fishing, as it has a great variety of fish species. Swimming in the lake is permitted.The lake is bordered by the following municipalities: Avignonet, Cognet, Marcieu, Mayres-Savel, Monteynard, La Motte-Saint-Martin, Roissard, Saint-Arey, Sinard, Treffort.

The Chemin de Fer de La Mure (La Mure railway) is a former coal-carrying electrified railway in (and owned by) the Department of Isère near the city of Grenoble, France, which lost its regular public passenger service from 2 February 1950 (although miners' trains continued until autumn 1962). It lost most of its freight traffic – apart from anthracite coal – in 1952, and even the anthracite ceased from 18 October 1988. However, the local tourist office had been chartering seasonal tourist passenger trains from 8 September 1968 and these developed steadily over the years, the line becoming one of the finest tourist railways in Europe with views over dams and lakes, and mountain scenery. Since 1 February 1998 the concession to operate the line and its tourist trains has been held by CFTA, now Veolia. The line can be reached easily by road from Grenoble, or by trains on the SNCF line towards Gap. On 26 October 2010, shortly before the end of the season, a landslide destroyed the Viaduc de la Clapisse and parts of a tunnel entrance. In June 2017, the General Council of the Department of Isère announced that the company Edeis had been chosen to repair the railway and take over its operation, with the aim of having it operational again for the 2020 season. Half the line eventually reopened in July 2021, from the top at La Mure as far as the viewpoint at Le Grand Balcon.
