Purpose. The study is purposed at assessing the intra- and inter-annual dynamics of nutrients concentration (compounds of inorganic nitrogen, phosphorus and silicon) in the Chernaya River waters. Methods and Results. The quarterly monitoring data on the water hydrochemical characteristics in the lower reaches of the Chernaya River and in the Chernorechenskoe reservoir obtained by Marine Hydrophysical Institute of RAS in 2015-2020 were used. The data obtained made it possible to study the distribution of inorganic nitrogen, phosphorus and silicon compound concentrations in the Chernaya River waters during the period under study, as well as its seasonal and interannual changes. As compared to 2010-2014, the ammonia nitrogen levels in 2015-2020 increased on average by 2.7 times. The mean long-term inorganic nitrogen outflow with the Chernaya River waters was 3 2.46 t/year in 2010-2014 and 27.8 t/year in 2015-2020, phosphorus and silicon - 0.23 and 57.93 t/year in 2010-2014 and 0.18 and 62.21 t/year in 2015-2020, respectively...
