The Site is the second largest inland delta in southern Norway. Situated where the rivers Etna and Dokka flow into lake Randsfjorden, it includes large shallow areas, mud banks, numerous channels, bogs, meadows and islets dominated by shrubs and alder/shrub gallery forest. As one of the few unspoilt estuaries remaining in the region, the Site is highly important for biodiversity preservation, as it supports numerous nationally red-listed species and a rich invertebrate fauna. It also has an important function as a staging area for several migratory bird species and as a spawning site for many species of fish. The Site is valuable in terms of sediment trapping, nutrient fixing and flood control. The regulation of Dokka river and Randsfjorden lake for hydropower production negatively affects the Site by reducing the flow of water through the delta by half. The National Wetlands Centre at the Site performs a range of tasks, such as education, guiding, management and monitoring of bird populations and flora. Popular activities include birdwatching and fishing.
