Maintaining good condition of dam reservoirs in urban areas seems increasingly important due to their valuable role in mitigating the effects of global warming. The aim of this study is to analyze possibilities to improve water quality and ecosystem condition of the Paprocany dam reservoir (highly urbanized area of southern Poland) using current data of the water parameters, historical sources, and DPSIR (Driver–Pressure–State–Impact–Response) and 3D modeling concerning human activity and the global warming effects. In its history Paprocany reservoir overcame numerous hydrotechnical changes influencing its present functioning. Also, its current state is significantly influenced by saline water from the coal mine (5 g L−1 of chlorides and sulphates) and biogenic elements in recreational area (about 70 mg L−1 of chlorate and to 1.9 mg L−1 Kjeldahl nitrogen) and in sediments (222.66 Mg of Kjeldahl nitrogen, 45.65 Mg of P, and 1.03 Mg of assimilable phosphorus). Concluding, the best solutions to improve the Paprocany reservoir water quality comprise: increasing alimentation with water and shortening the water exchange time, restoration of the 19th century water treatment plant, and wetlands and reed bed area revitalization. The study also proved the applicability of mathematical models in planning of the actions and anticipating their efficiency.

Depth Analysis

Reservoirs are formed through the artificial damming of a river valley. Reservoirs, among others, capture polluted load transported by the tributaries in the form of suspended and dissolved sediments and substances. Therefore, reservoirs are treated in the European Union (EU) as “artificial” or “heavily modified” surface water bodies. The reservoirs’ pollutant load depends to a large extent on the degree of anthropogenic impact in the respective river catchment area. The purpose of this paper is to assess the mutual relation between the catchment area and the reservoirs. In particular, we focus on the effects of certain land use/land cover on reservoirs’ water quality. For this study, we selected twenty Polish reservoirs for an in-depth analysis using 2018 CORINE Land Cover data. This analysis allowed the identification of the main triggering factors in terms of water quality of the respective reservoirs. Moreover, our assessment clearly shows that water quality of the analysed dam reservoirs is directly affected by the composition of land use/land cover, both of the entire total reservoir catchment areas and the directly into the reservoir draining sub-catchment areas.

Abstract There is still a controversy about the environmental impact of fishponds, especially on their ability to retain nutrients. This paper presents some basic rules of nutrient cycling in running and stagnant waters and the biotic and abiotic transformation of nutrients delivered to dam reservoirs and fishponds. Based on these common properties of eutrophic stagnant waters, some critical remarks are presented on papers that claim to prove the capacity of fishponds to retain nutrients (mainly nitrogen) during fish production and after pond drainage. Finally, some ways of reducing negative environmental impacts of fishpond effluents are described as an indirect evidence that such impacts really pose a threat to water quality

Modelling Studies

The empirical and modelling limnological studies of the reservoirs of the Vltava Cascade spanning over 30 years have demonstrated the major differences between stratified throughflowing reservoirs and lakes. The most significant limnological differences are caused by the generally deep outflows due to the extreme position of the maximum depths, and high flow rates causing flow-driven gradients. Limnological conditions in dam reservoirs are very sensitive to the theoretical retention time of water in the reservoir (RT), in particular in the range RT < 200 days. The primary effect of the high inflow rates is the weakening of stratification, due mainly to increasing bottom temperatures leading to deeper mixing, which results in lower surface temperatures. The hydrophysical changes subsequently affect the fate of chemical constituents and the primary production; the effects are propagated to higher levels and fed back to both chemical and physical water quality. A reservoir being second or successive in a cascade differs limnologically in that it is affected by the dominantly hypolimnetic releases of the upperlying reservoir. The differences in hydrophysics, hydrochemistry and hydrobiology have been specified and the findings are, in general, supported by modelling studies.

The paper presents the water classification of four small retention reservoirs on the basis of selected physical and chemical indicators, such as: conductivity, pH level, dissolved oxygen, calcium hardness, general hardness and alkalinity. Three reservoirs (Ożanna, Kamionka and Cierpisz) are within the limits in terms of average values for the second class of water quality. Water in the Nowa Wieś reservoir does not qualify as second quality class of surface water. These reservoirs have had very irregular seasonal variations of water quality. Unambiguous correlations have not been established. Aggressive properties of water have been tested on the basis of Langelier (IL) or Ryznar (IR) indexes and calcium carbonate saturation [pHs]. Waters in the Ożanna and Nowa Wieś reservoirs do not have aggressive properties. Both the Kamionka and Cierpisz reservoirs are characterized by corrosive and leaching aggressiveness.
