In Trollhättan the Trollhätte canal starts, connecting the Kattegat (west coast) with lake Vänern. Just outside the center of town, there are several sets of locks. A first set of small locks from 1800, which are now derelict. A second set of locks from around 1844. A third set of locks from 1916, which are still in use today. About 10 freight ships per day pass the locks today, and throughout the summer months about 4000 leisure boats pass by.
