The lake provides drinking water, supplies and generates electricity and offers a range of watersports. Swimming is allowed only in marked areas and the water temperature is usually warm enough from June to September. Sailing and windsurfing are very popular and there are a number of sailing schools as well as companies hiring out boats and windsurfing boards. The best resorts for sailing and windsurfing are Insenborn, Lultzhausen and Liefrange. Further lakes where waterports can be pursued are at Echternach, Remerschen and Weiswampach.
Trout is a popular catch.
Many country hotels have their own fishing grounds which are open to guests, and where the chef will be pleased to cook the day's catch. Fishing licences are required and issued by the District Commissioners of Luxembourg, Diekirch and Grevenmacher, as well as by different communal administrations. Contact the Luxembourg National Tourist Office for details. The mild, sunny climate of the Moselle is ideal for wine-making. White wines such as Riesland, Rivaner and Elbling are the most popular.
