In this article, the results of detailed experimental investigation of main ions in waters within a small river basin are considered. The data were obtained on the base of comprehensive hydro-logical and geochemical monitoring of natural waters along semi-movable or expeditionary field studies during warm periods of 2011 and 2012. According to main ions, water samples were split onto seven genetic water classes as 1) cyclonic rain, 2) intermittent rain, 3) throughfall, 4) talus flow, 5) low-water streamflow (specific discharge is less 2.5 l/s×km 2), 6) low flood streamflow (specific discharge is more 2.5 and less 16 l/s×km 2), and 7) medium flood streamflow (specific discharge is more 16 and less 100 l/s×km 2). Also, there were identified the four main groups of riverine dissolved macro-compounds that differ in terms of type of their dependence with flow rate. They are a) the compounds directly dependent with flow rate, b) the compounds inversely dependent with flow rate, c) the compounds independent evidently with flow rate, and d) the compounds that are charac-terized by complicated (fuzzy) dependence with flow rate.
