The Langevensche Loop (also: Langevense Loop) is a dug watercourse used to drain agricultural land.
The approximately 8-kilometer-long stream begins near the hamlet of Ulfterhoek, part of Sevenum. It flows northeast, eastward along the Reulsberg.
East of Melderslo, the stream turns right towards a nature reserve called Schuitwater and is from there known as Broekhuizer Molenbeek.
This branch will be closed in 2024 to keep foreign water out of the Schuitwater. The storage and discharge capacity of the Boabel will be increased for this purpose.
A branch of the Langevense Loop, the Boabel, flows north around the Schuitwater and also flows into the aforementioned Broekhuizer Molenbeek. This latter stream may be partly of natural origin and flows into the Meuse River.
Among the fish species are the small sand loach and the small mud crawler.
