The Wehebach dam is located between the Hürtgenwald in the Düren district and Stolberg (Rhineland) in the Aachen city region in North Rhine-Westphalia . It was put into operation in 1983 for flood protection , drinking water supply and low water elevation . Below the dam, the Wehebach flows further into the Inde and Rur . The dam belongs to the Eifel-Rur Water Association (WVER).
The reservoir
The Wehebachtalsperre reservoir has three arms: in the west the valley of the red Wehebach, to the east that of the Wehebach (also known as the white Wehe) and in the west-east axis the valley of the Thönbach.
The dam
The dam is a rock rubble dam made of slate and greywacke with a bituminous outer seal and an additional bituminous braking zone (bitumen sand) in the core. This was built in to protect against earthquakes . A withdrawal tower with an adjoining tunnel is used to withdraw drinking water. The flood relief is on the right slope. It has a fan-like, 24-meter-wide overflow with a 6-meter-wide chute that goes over the valley flank and ends in the stilling basin . The dam has an inspection passage in the hearth wall on the water side and two berms on the air side .
The drinking water treatment plant is located below the dam.
Tributaries of the Wehebachtalsperre
In addition to the main tributaries Roter Wehebach, Weißer Wehebach, Weberbach and Thönbach, the Wehebachtalsperre is fed by a number of other streams. The graphic arms of the Wehebachtalsperre shows an overview of the reservoir. Referring to the graphic, the Rote Wehebach feeds arm "1", Weißer Wehebach and Weberbach feeds arm "2" and Tönbach feeds arm "3".
Definition of Weißer Wehebach: In vernacular usage and shown on some maps, the upper section of the Wehebach, the section from its source to the confluence with the Wehebachtalsperre, based on the Roten Wehebach, is called the Weißer Wehebach. The Wehebach has a total length of 25,696 meters.

(*) = The confluence with the receiving water is inside the lake.
There are two rivers with the names "Roter Wehebach" and "Rothsiefen".
Touristic
An elevated vantage point directly on the dam offers a view over the barrier structure and parts of the lake. The only leisure activities allowed are hiking and cycling, as the lake is not approved for water sports due to its character as a drinking water reservoir. Due to its location in a wooded area, the reservoir offers the opportunity for mainly ornithological nature observations.
To the east of the dam are the remains of the ring wall of a Celtic refuge from the Iron Age .
At the influence of the white Wehebach there is a road bridge of the former Nideggener Straße or Schevenhüttener Straße. This, along with large parts of the road, was not dismantled, but left to the water and is accessible at low tide ( location ).
power plant
A cross- flow turbine with a nominal output of 0.053 MW has been operated for energy use since October 2011 . It stands in the outlet structure of the dam. With a flow rate of 100 to 200 liters per second, the annual consumption of up to 100 households can be covered.
