The Iešjávri (also Jiešjavri ) is a lake in the northern Norwegian province ( Fylke ) Troms og Finnmark . The Iešjohka river is an outflow from the lake, which in turn flows into the Karasjohka .

Ecological condition

The maximum depth is 41 meters, with visibility being given as ten meters in 2018. In the 442 km² catchment area there are neither agricultural areas nor dense buildings. A study in 2018 by the Norsk institutt for naturforsking (NINA) showed that the ecological condition of the lake was very good. According to the report, the values are almost exemplary. The pollutant values were classified as very low. The water temperature in Iešjávri reached 15 ° C in July. One of the reasons for the low temperature value is that the lake is located in a windy area.

Eight different types of fish live in the lake, the most common of which are arctic char . There are also ten species of aquatic plants in Iešjávri. The NINA tried to justify this rather low number with the strong waves on the bank due to the windy conditions.

Surname

The name is North Sami and means "big lake". The Norwegian name for it would be Storvatnet .
