The paper presents the results of research into the hydrological features and geoecological state of small watercourses in the polder territories of the Kaliningrad region. The work is focused on the largest polder massif of the region located on the territory of the Neman lowland in the Slavsky urban district. There was carried out geoecological monitoring of surface watercourses in the following seasons: summer (July 15, 2020), autumn (October 15, 2020), winter (February 3, 2021), and spring (March 27, 2021). For the monitoring we selected watercourses that in their totality could characterize the river network of the polder massif as a whole: the rivers Zlaya, Shlyuzovaya, Nemoninka, and Osa. Subsequently, water samples were taken for hydrochemical analysis, and the hydrometric characteristics of the rivers were measured at background and control points. In order to more objectively characterize the hydrological features of the river network, in addition to the results obtained during the monitoring, we used data on long-term hydrological observations. The research provides information on the state of the watercourses and the influence of anthropogenic and natural factors on them. Monitoring of the geoecological state has shown that they are to a greater or lesser extent susceptible to pollution and, in general, have a ‘bad quality’ water class. The main pollutants identified in the course of research were: nitrites, ammonium, phosphates, total iron, and oil products. There are also inconsistencies with the norms of maximum permissible concentrations in terms of biological consumption of oxygen and dissolved oxygen that are noted during the period of activity of living organisms. The geoecological state was found to be linked to the water regime, weather conditions, natural and agricultural cycles. A non-standard course of the water regime phases was noted, namely: autumn-winter floods, not very pronounced high water, and summer low water. The current situation of the river network can be characterized as unfavorable but still having a potential for correction due to the properly selected environmental protection measures.

“…Как отмечалось в прошлых работах [1][2], речная сеть сильно уязвима к природному и антропогенному влиянию, которое носит сезонный характер, то есть меняется внутри года со сменой сезонов. Для выявления степени негативного влияния целесообразно произвести сравнительный анализ гидрохимического состояния по гидрологическим сезонам.…”

“…С учетом данных наблюдений за азотными соединениями по трем сезонам складывается следующая ситуация. В летний период их высокое содержание имело два потенциальных источника -сельское хозяйство и разного рода воздействие живых организмов [1]. Осенью из-за благоприятных погодных условий для флоры и фауны мы наблюдали схожую с летним сезоном их активность, но при этом концентрации азотных веществ существенно уменьшились [2].…”

“…Это в свою очередь может показывать отсутствие корреляции между разложением органики и действием гидробионтов с серьёзными превышениями концентраций азотных характеристик. Поэтому летом превышения по ним можно связать с вымыванием заложенных в период вегетации азотных удобрений, а отсутствие их осенью подкрепляет это предположение [1][2]. Эти аргументы указывают на значительное влияние сельскохозяйственной деятельности на водотоки территории.…”

The aim of the work is to research the chemical composition of surface watercourses in the Slavsky district of the Kaliningrad region in the winter hydrological season, and to compare the results with the data previously obtained by the authors for the autumn hydrological season and partly for the summer hydrological season. Watercourses and monitoring points for research have been identified: r. Zlaya, r. Shluzovaya, r. Nemoninka and r. Osa. In the winter season, water samples were taken, hydrometric characteristics were measured, and primary hydrochemical indicators were determined. On the basis of the obtained hydrochemical data, integral indicators were calculated to assess the quality of water, using combined lists of maximum permissible concentrations of pollutants. When monitoring hydrochemical indicators, it was revealed that the studied watercourses are, to one degree or another, subject to pollution. The water quality class in them varies from "moderately polluted" to "extremely dirty". When comparing the seasons, a tendency was revealed to improve the quality of water, which is associated with the water content of rivers, as well as with the cycles of natural and anthropogenic activity. The work has theoretical and practical significance. The data can participate in the planning of rational use of natural resources and the selection of measures to improve the geoecological state of the river network of the Slavsky region. The research can serve as a supplement to the formation of the general geoecological picture of the Kaliningrad region.
