This article is a continuation of the topic of artificial water bodies in Ukraine, which was started in our previous publication in 2020. It was devoted to accounting and monitoring of ponds at the local and national levels. Reservoirs play important role in water supply for various sectors of the economy. For this reason, much more attention is paid to reservoirs by the State Agency of Water Resources of Ukraine (Ukr. Derzhavne ahentstvo vodnykh resursiv Ukrainy), the Ministry of Ecology and Natural Resources of Ukraine (Ukr. Ministerstvo ekolohii ta pryrodnykh resursiv Ukrainy), scientists and specialists. The main tasks of the article are: to establish patterns of territorial distribution of reservoirs in administrative regions and river basins districts; to identify the role of large and small reservoirs in the balance of river runoff regulation. There are 1054 reservoirs in Ukraine, so it can be considered a country rich in reservoirs. The volume of the cascade of six reservoirs on the Dnieper River and the Dniester Reservoir is 85%, other reservoirs – 15% of the total number. At the same time, there are 1047 other reservoirs (middle, small and very small), which provide for regional needs and which have their own patterns of distribution throughout the country. The main trend in their creation was water supply of industrial regions, in particular Kharkiv, Donetsk, Dnipropetrovsk and others. About 28% of reservoirs are leased. These reservoirs also require clear accounting and monitoring at the national level, attention from water management and environmental organizations.

The purpose of the study presented in the article is to implement modern hydrographic characteristics of freshwater of the Shatsk Lakes (28 lakes in Volyn Polissya, Ukraine) by typing water bodies according to the requirements of the EU Water Framework Directive, assessment of the chemical composition of lake water and bottom sediments (sapropel), determination of the opportunity for their recreational use in the special status of the district as a national park. Despite the presence of the two large lakes (Svityaz - 26.2 km2 and Pulemetske - 15.5 km2), very small lakes with a water surface area of less than 0.5 km2 (64%) are dominating in the Shatsk group. Mineralisation of calcium-hydrocarbonate lake waters is 115-303 mg∙dm-3 and calcium-sulphate aqueous extract of sapropel is - 318-1451 mg∙dm-3. Using a Piper diagram, it was found that there is genetic homogeneity between surface and groundwater, indicating a significant share of groundwater in the water supply of lakes. There are eight species of sapropel deposits in 19 lakes of the district. A wide range of chemical composition and physical and mechanical properties of sapropel deposits of the Shatsk Lakes allow us to consider them as an important resource for agriculture and industry. We found that sapropel from Shatsk Lakes meets the requirements for therapeutic mud and can be used for therapeutic and health purposes.

The purpose of the research is to establish the total number of ponds in Ukraine and to analyse the territorial distribution in the administrative areas, as well as in the river basin districts, as the main hydrographic units of water management. Cadastral data of the State Agency of Water Resources of Ukraine regional offices as of 2019 was used in the research (as to Crimea, Donetsk and Luhansk regions we applied the data as of 2014). According the researches there are 50,793 ponds in Ukraine with a total water table area of 2,92899 ha and the volume of 3,969.4 mln m3 of water in 2019. The quantitative distribution of ponds across Ukraine is unequal. Most of them are concentrated in the central part of the country (10.5% of the total number of ponds in the country are in Vinnytsia region). Least of them are in Luhansk region (0.7%). Almost half of the ponds are located in the Dnieper River Basin (48.5%). The lowest quantity of ponds is in the Black Sea Basin (1.2%). The regulation of river basins districts (the rivers of the Sea of Azov, Crimea and Black Sea Basins) reaches 0.71–0.77. As of 2019, 28% of the ponds are rented out. In order to identify the real status of the ponds (both quantitative and qualitative), their recreational role, the environmental impact and the regulation of the hydrographic network in Ukraine, it is necessary to increase the attention to ponds monitoring.
