A couple of notable events that have happened in this location are when Zug and Zorran "accidentally" blocked the river with an old tramper in Trapped, and when Sunshine was trapped in a log jam fire in Up River. The river is also where Sunshine lived before he came to Bigg City Port. Sea Rogue and his uncle lived there too before his uncle was held into ransom by The Pirates to make Sea Rogue steal barges. It is also the home of Boomer after he was refurished into a house boat and now lives in Dun Tugging. Uptown, Mittsville, Top Town and the Munitions Factory are all located here.
- In an interview, it was stated that many of the planned episodes of Season 2 were to take place Up River because it was easier to film there.
