Lake Meðalfellsvatn in Kjós is about 2 km² in size and has a maximum depth pf about 18 m. It is 46 meters above sea level. The rivers Sandsá and Flekkudalsá run to it, and the River Bugða falls out of it into Laxá in Kjós. The catch is mostly small char, but also some brown trout, sea trout and salmon. Salmon often migrates up to Meðalfellsvatn and people have caught salmon there from the middle of summer until the end of the fishing season. There are a lot of small char in the lake, making it very suitable for children and families. Good fishing places in the spring are off Grástein and Skógar, under the southwest slope, as well as at the mouth of river Sandsá. As the summer progresses, the fishing is widespread on the lake and most places are equally good.
