Water quality and discharge data of Kuonanjoki sub-catchment of Lake Puruvesi

The water quality and discharge has been monitored using continuous device in Kuonanjoki sub catchment of Puruvesi. Following parameters have been monitored: chlorophyll-A, cyanobacteria, electrical conductivity, water temperature, oxygen, total and dissolved organic carbon, turbidity, suspended solids and total phosphorus in addition to discharge and velocity of the stream. Presented data is the latest validated data from period 24.10.2019 - 4.11.2021 (interval of 30 min.). Monitoring has been conducted by Luke as part of the Horizon 2020 project Operandum (https://www.operandum-project.eu/the-project/) and South Savonia Ely center.

Kuonanjoki catchments is part of the Lake Puruvesi catchment, locating in eastern part of Finland. The size of Kuonanjoki catchment is 73 km2, including forest (75% of land area), of which 30 % is peatland forest, in addition there is agricultural area (4%) and water bodies (21%). The former human activities such as ditching of peatlands, have caused increased nutrient (e.g. phosphorus and nitrogen) and suspended solids loads into the lakes of the catchment, and further increased risk of eutrophication and siltation of lakes. Hazard of increased leaching of nutrients and suspended solids may be accelerated by heavy precipitation events caused by climate change.
