Analysis of the hydro/chemical regime and spatial regularities of the water composition changes in the Vasyugan Bog North-Eastern part between the Bakchar and Iksa rivers is presented. It has been noted that the chemical composition transformation with water class, group and type during the year is a special feature of the high bog hydro/chemical regime. Within the bog limits three clusters have been identified by bog waters chemical composition characteristics on the basis of the cluster analysis. Reliable differences between the tree clusters have been determined by the mineralization amount, Са2+, Mg2+, Feобщ, NH4 +, NO3 - ions, humic and fulvene acids, Сорг and СО2 content. Analysis of the seasonal indices has demonstrated that during the vegetation period two significant maximal peaks of the bog water seasonal wave of chemical composition occur, namely in March and September. It has been noted that that the near-ground air temperature sum increase more than 10 ºС is accompanied by the pH increase in the high bog water, increase of СО2, ammonia, sulphate, iron ions, and organic matter (humic and fulvene acids, Сорг).
