“…51 Since 2013, the water levels of Burabay and Shortandy Lakes have been steadily increasing while Ulken Shabakty water levels remained approximately stable ( Figure 5). There are similar trends between long-term water level changes in endorheic lakes of Canadian praries 34 and BNNP lakes. The higher lake levels a century ago in both regions are attributed to wetter conditions.…”

“…9,34 van der Kamp et al 34 reported a 9-m decline for Redberry lake between 1918 and 1986,while Kazhydromet estimated the drop of Ulken Shabakty' water level to be more than 10 m since the middle of last century to 2000. 9 The decline in Canadian prairie lakes levels is associated with land-use changes leading to a decrease in runoff to the lakes, and an increase in evaporation, as a result of rising air temperatures especially in the spring-time period.…”

The changing water cycle: Burabay National Nature Park, Northern Kazakhstan

Water resources in Central Asia are scarce, so complicated issues arise from this. Kazakhstan is a Central Asian landlocked country, which has mostly closed drainage basins, characterized by endorheic lakes that do not drain to the oceans. These endorheic lakes are very sensitive to climate change and anthropogenic influences. Very few studies have been conducted on the hydrological cycle of the small endorheic lakes. This work reviews the endorheic lakes within Burabay National Nature Park (BNNP), Northern Kazakhstan. BNNP is a small ecozone consisting of terminal lakes watersheds covered by mixed forests and grasslands. These endorheic lakes have been drying out during the last one hundred years or so with the water level decrease accelerated in the past few decades. According to historical observations , on the one hand precipitation amounts did not significantly change, while on the other hand, air temperature steadily increased. The lake level decrease is most probably caused by a water budget deficit, with evaporation exceeding the precipitation inputs in the long term. The direct anthropogenic impact (water abstraction) plays a minor role in the deterioration of water levels, with most significant impacts through localized land-use changes such as road and building construction in the catchments. The future of the park's sensitive ecosystems in a changing climate is uncertain; therefore, BNNP requires modern ecohydrological monitoring methods and analysis tools to improve our understanding of its hydrological cycle variability, and to enable us to develop adequate adaptation and mitigation measures.

“…Changes in lake water volume are calculated based on the fluctuations of water level in the lake which are a function of the balance between precipitation on the lake, runoff to the lake, evaporation, abstraction and groundwater outflow from the lake [11]. Water volume in Badovc Lake on January 01, 2014 was 9,509,000 m …”

This paper aims to evaluate the water balance for Badovc Lake, Kosovo based on the hydrological monitoring made in the period 2013-2014. The recent bathymetric data showed that the current maximum volume (corresponding to height of 649.75 asl) of the lake is 25,590,000 m 3 , being 1,000,000 m 3 less than the initial volume due to the sedimentation on the lake bottom. The average annual rainfall in the dam was 860.7 mm being higher than its historical value (642.0 mm). The overall water inflow into the lake was 22,577,663 m between the above water volumes may be considered as "water loss" from the lake. This amount of water represents around 17% of the total volume of lake, or around 35% of its current water abstraction. The hydrologic balance of the lake watershed will further clarify the factors that are responsible for this "water loose" from the lake. In addition, the results of this study will help the authorities to better manage the water intake.

“…Changes in the water volume of Lake are calculated based on the fluctuations of water level in the Lake which, in turn, are a function of the balance between precipitation on the lake, runoff to the lake, evaporation, abstraction and groundwater outflow from the lake (Van der Camp et al, 2008). Water volume in Badovc Lake on January 01, 2014 was 9,509,000 m³ while on December 3aa2, 2014 it was 16,853,000 m³ that corresponds to water level 637.15 m and 643.60 m (a.s.l) and surface water area of 0.92km 2 and 1.38km 2 , respectively ( fig.…”

This paper aims to evaluate the water balance and possible water losses for Badovc Lake -Kosovo based on the hydrological monitoring made during the year 2014. A decrease of 1,000,000 m³of the lake physical volume, due to the sedimentation on the lake bottom, was revealed by the recent bathymetric survey which found that the current maximum volume (corresponding to height 649.75 mabove sea level (a.s.l)) of the Lake is 25,590,000 m³. The average annual rainfall of the basin was 860.7 mm, whereas the overall water inflow into the Lake was 22,577,663 m³. The annual amount of the calculated evaporation from the Lake surface was 849,535 m³ (or 644.50 mm), while an annual infiltration rate of 94,608 m³ through the clay screen was reported. A quantity of 10,550,615 m³ water was abstracted from the lake during 2014. A residual water volume of 11,082,905 was evaluated considering the above cited inflow and outflow quantities (22,577,663 m³ and 11,494,758 m³, respectively). On the other hand, the positive volume (7,344,000 m³) of the Lake in 2014, calculated according to water level variations, was3, 682, 905 m³ less than the above residual water volume. This difference between the above water volumes is considered as "water loss" from the Lake and it represents about 17% of the total volume of Lake, or 35% of its current water abstraction. This water loss from the lake was attributed to water infiltration through cracks that involved geological formations of the lake bottom and beneath its dam, possibly towards the nearest Hajvalia mine.
