Region: Southern

Height: 12 ft (4 m)

River: ├×j├│rs├í

Urri├░afoss is Iceland’s largest waterfall in volume, with a high river drop rate of 12,700 cfs (360 cms). The waterfall is located on the ├×j├│rs├í, the longest river in Iceland. In Icelandic, Urri├░afoss translates to “Trout Waterfall.” The ├×j├│rs├í is a famous river for salmon and trout fishing. Even seals are reported to travel up the river to Urri├░afoss to catch salmon.┬á

In terms of height, Urri├░afoss is relatively small, standing at only around 12 ft (4 m). However, it stretches across the ├×j├│rs├í river, creating several small islands with an average width of 750 ft (229 m). Ice can build up on the waterfall upwards to 98 ft (30 m) during cold conditions, causing the river to overflow.

The river is also set on the edge of the ├×j├│rs├írhraun lava field. This lava field resulted from the greatest lava flow since the Ice Age.

As mentioned, Urri├░afoss is the most voluminous waterfall in the country, and this is after nearly a 50% reduction due to 5 established dams on the ├×j├│rs├í. However, there is a proposal for a hydropower station to be built at the lower end of the waterfall. In terms of energy, the volume of water flow around Urri├░afoss would make it an ideal resource. Unfortunately, if this were to be constructed, this could be the end of Urri├░afoss. This has sparked many protests to save the waterfall and protect the ecosystem of the ├×j├│rs├í, as this area is where the most freshwater marine life of the river can be found.
