History:
Tista canal follows the Tista River from the sea to Tistafossen. From the start obviously the thought was to build locks beside the waterfall and connect the canal to Femsjøen and the Halden canal. But that was a very difficult and way to expensive task.
The Tista canal was built in 1909 and there are two lock stations. The first, Porsnes, is located about one kilometer from the sea, just upstreams the Halden center. Skonningsfoss is located a further kilometer upstreams. The whole canal is about 3,5 kilometers long. Upstreams it ends at the bottom of the waterfall Tistedalsfossen. Here the canal was connected to a log flume from Femsjøen and the place is called "Gryta".
Skonningsfoss locks have been out of use since 1979, while Porsnes still can be used.
Poersnes lock has one chamber and an elevation of 2,5 meters and Skonningsfoss two chambers, each with an elevation of 3,5 meters. All locks are 32 meters long, 7 meters wide and with a depth of 2,5 meters.
The upstream gates are the only reminders of Skonningsfors lock. The chambers have been rebuilt to salmon ladders.
Porsnes lock may possibly still be used, but there are low modern bridges built across the chamber.
