In this paper we will present results from field measurements at the River Kymijoki gathered during winter 2011/2012.

River Kymijoki is located in southeast Finland, it freezes annually, and the catchment area of the river is 37 107 km2 which is about 11 % of the area of Finland. The lake percentage of the river catchment is 19 %. Aim of this first stage of the research project was to select measurement points and evaluate their suitability to present the River Kymijoki ice and water quality phenomena. Other goal for the project was to examine the collected data and process a comprehensive image of the River Kymijoki ice phenomena and water quality.
