Source: de.wikipedia.org/wiki/LeerbachNatural Monument Leerbachquelle (Jannings Quelle)
The Leerbach spring near Leer at the foot of the Schöppinger Berg, also called Jannings Quelle after an old name of a neighboring farm, is an important natural monument in Münsterland.
At Schöppinger Berg there are rocky calcareous sand and limestone rocks of the Upper Campan on the clay-permeable, water-impermeable "Osterwicker layers" of the sub-campan. The water penetrates the upper layers and accumulates on the trough-shaped curved Osterwicker layers. On a source horizon at the height of about 90 m above sea level. NHN enters the water in several sources, of which the Leerbachquelle is the most productive, from the mountain. The spring pot measures eight to ten meters in diameter and has up to 14 water outlet points. The bed of the karst source  is between 25 and 100 liters per second, only in the extremely dry summer of 1976, the source dried up. The spring water has a little fluctuating temperature between 8 and 11 ° C during the year. Due to the constant conditions, a special flora and fauna has developed in the source area. The barriers around the biotope should be respected.
