Geography
Its source is located on the plateau of Saint-Hubert. It passes through the villages of Poix-Saint-Hubert, Smuid, Mirwart, Grupont, Lesterny, Forrières, Jemelle, and the town of Rochefort, where it carves the Lorette cave. It joins the Lesse river at Éprave. The Lomme river is fed by the Lomme river basin, which is made up of predominantly peaty bogs. The Lomme river valley is home to the longest Karst in Belgium.
In 2010 the European Commission began a project to restore the Lomme river basin, in 4 years the project restored 430 hectares of hydrological networks.
