Published 16 August 2022 When you take a dip in a Swedish lake, it is not unusual to find you cannot see the lake bottom. Lake water coloured brown by organic material can be an inconvenience for swimming tourists, but mainly causes problems for the ecosystem and drinking water. Focusing on Lake Bolmen, researchers, public authorities and local organisations are now joining forces in a research pr
