As a representative example of an inland water system in northern Europe the Lake Puruvesi tends to suffer from nutrient and loads. Surface runoff caused by extreme precipitation or excessive, rapid snow melt produce nutrient leaching especially from heavily managed forests. Citizen science has potential to address to risk of eutrophication of Lake Puruvesi. Firstly, forest owners need to be engaged to the project to co-design and co-develop nature-based solutions including information about forest management options to reduce nutrient leaching. Secondly, to improve understanding and modelling  standard observational network should be enhanced. The extreme precipitation in the area is monitored throughout the year with, in particular, for this project established automatic precipitation station. Additionally, during the winter season a group of citizen volunteers measure manually snow depth and snow density in the catchment area of Lake Puruvesi. The precipitation and snow data collected with in-situ and satellite measurements are analyzed to indicate the relationships of the nutrient flows and precipitation in the area. Here we present the preliminary results from the measurement campaign from the period January-April 2020.
