With yacht on Trollhätte Canal
The Trollhätte Canal
The Trollhätte Canal is 82 km long. 10 km of which are manmade, the remainder being a natural waterway – The Göta Älv River. The difference in level between Lake Vänern and the sea is 44 m. This change is catered for by six locks: one in Lilla Edet of 6 m. four at Trollhättan of 32 m. total and one at Brinkebergskulle of 6 m. Double bottoms in the locks ensure an even distribution of the water. This makes for gentle water movement, during both filling and draining. 8000-12000 m3 of water is required for each lock operation. Minimum water depth in the main canal is 6,3 m and the treshold depth of the locks is 5,7 m at the lowest water level.
The Locks
The opening of the first locks, in 1800, allowed ships with a freight capacity of 140 tons to pass through. Today, nearly two hundred years later, a modern Vänermax freighter carries up to 4000 tons in regular traffic. These ships are 89 m long, have a beam of 13,4 m and a draught of 5,4 m. Annually over 3,5 million tons of goods are shipped on the canal. The development of new and larger ships has also increased the canal’s capacity. With today’s ships it is possible to double the capacity of the canal without large investment.
With a boat on Trollhätte Canal
All locks and bridges along the canal is under CCTV surveillance. The opening of bridges and locks are therefore controlled remotely from different stations along the channel, for example in Lilla Edet, Trollhättan and Brinkebergskulle.
Before raising the bridge, pleasure craft are to keep as close to the bridge as possible, in order to decrease the time the bridge is raised. Bridge and lock openings are announced via electronic signs.
There are some important phone numbers you will need with you when you are travelling along the channel. These can be found in the overview map below.

Waiting times at locks: Commercial traffic precedence.
At highway bridges: During heavy traffic, boats gather in wait for bridge to open.
At railway bridges: Rail traffic control openings of railway bridges.
