Tibbs River

The 90-km-long (56 miles) Tibbs River flows southwest from the northern border of Eleleno until it joins the Ivir River. The northern quarter of the riverbed is rock with several fordable locations. The remaining river is wider with marshy shorelines and a bed of thick silt. The primary source of the river is Lake Ugo, named in honor of Ugo Eleleno, who civilized the land.

The river is navigable along its entire length for shallow-bottomed boats. During the heat of summer boats have to be pushed or pulled through the most southern stretches where the depth can be only a few inches.
