Serrig Lock and Hydroelectric Power Plant

The Serrig barrage is Germany's largest river barrage on a natural river course.

The Serrig barrage was built between 1981 and 1986 and has a lifting height of 14.5 m. The underwater is at 142.00 m above sea level and the storage target is at 156.50 m above sea level.

The barrage has two lock chambers, the larger of which is 190 m long and 12.07 m wide. The smaller one is 40 m long and 6.70 m wide. The average rate of climb is 1.40 m per minute, resulting in a filling time of around 10.2 minutes.

A hydroelectric power station is part of the barrage. The output of the two bulb turbines is 12 MW.

Very impressive system and a magnet for spectators who watch the lock process in the immensely deep lock chambers.
