Cottesserbeek and Beversbergbeek
Cottesserbeek
You are near the Cottesserbeek here. It flows upstream into the Geul ult. The Cottesserbeek is also called the Grensbeek because it forms almost the entire border between the Netherlands and Belgium. At the junction with the Cottesserbeek, the Geul flows into the Netherlands.
A few hundred metres upstream from this peak is a measuring point of the Limburg Water Board. The amount of water that flows into the Netherlands via the Geul is measured there every day.
Length 1.8 kilometres.
Average discharge 8.5 litres per second. Average flow rate 0.15 m/second Characteristic always water-bearing
Berversbergbeek
Downstream we pass Hoeve Bervers. The stream that flows right past it bears the name of that farm: the Berversbergbeek. This stream rises at the edge of the forest of the Vijlenerbos at 150 metres above N.A.P. to then flow into the Geul at 120 metres above N.A.P., From several sources on the edge of the forest a small pond first arises. The spring water then dives freely I as a stream down with a steep drop over a short distance (130 metres over a length of 1,800 metres). Along the source stream are moist hayfields and a few marshes. Higher up, poor ditches, wooded banks, hedges, pools and sunken roads beautify the landscape.
Rich flora and fauna
Along the source stream grow, among other things, rough bedstraw, few-leaved gold-veil and pointed hawkweed. Due to the alternation of moist and dry conditions, it is an ideal habitat for amphibians. For example, the alpine newt, the palmate newt, the midwife toad and in some places the equally rare fire salamander can also be found here. The transition between the forests and the stream valley is a suitable habitat for mammals such as the hazel dormouse and the Daubenton's bat.
