• Practical example:

The Wiehl dam gives a good example for the practical operating conditions of a dam. The Wiehl dam serves primarily as a drinking water supply and a means for flood protection, and secondarily for energy production. In addition, a minimum flow of 100 l/s has to be guaranteed downstream of the Wiehl dam. The first priority is the drinking water supply. In order to ensure sufficient water quality in the reservoir, additional discharges used for energy production are stopped when the reservoir volume falls below 70% of the total volume. As both the minimum discharge and the turbine discharge leave into the Wiehl, it would also be uncalled-for to maintain the minimum discharge if water was simultaneously discharged through the turbine. This results in a reduction of a discharge A (minimum discharge) by the amount of discharge B (turbine) as described above.
