Lake Thingvallavatn monitoring project

According to reg. no. 650/2006 for the protection of water quality and biota of Þingvallavatn and its catchment, the lake and water within the catchment is defined as a sensitive receptor and water quality shall comply with the most stringent standards, i.e. class A (reg. no. 796/1999).

In year 2007 a monitoring programme was started to assess chemical and biological quality of Lake Þingvallavatn Iceland.

The programme is run by The Environment Agency of Iceland (Umhverfisstofnun), Landsvirkjun (the national power company), Reykjavík Energy (Orkuveita Reykjavíkur) and The Thingvellir National Park (Þjóðgarðurinn á Þingvöllum).

There are three major work tasks in the program:


1) physico-chemical factors in inlet and outlet water, executed by Institute of Earth Sciences (Jarðvísindastofnun), 
2) biological and physico– chemical factors in the pelagic habitat, executed by Natural History Museum of Kópavogur (Náttúrufræðistofa Kópavogs) and 
3) fish populations, executed by Institute of Freshwater Fisheries (Veiðimálastofnun).

Reports on the findings can be downloaded in Icelandic with English abstract.
