“…Lakes are one of the main components of natural water retention. Current research [54] analysing the course of natural components affecting changes in surface areas of lakes, i.e., precipitation and air temperature (and as a consequence increase in evaporation) showed an increase in the latter with relative stability of the former. Such a situation should be considered unfavourable and requiring further detailed research (among others with consideration of teleconnection patterns) aimed at the development of solutions hindering the reduction of easily available water resources accumulated in lakes (e.g., through the expansion of hydrotechnical infrastructure, etc.…”

Abstract:The objective of the paper was the determination of the effect of teleconnection patterns (North Atlantic Oscillation (NAO), Arctic Oscillation (AO), East Atlantic pattern (EA), East Atlantic/Western Russia (EAWR), and Scandinavian pattern (SCAND)) on changes in air and water temperature in Polish lakes. Correlations of circulation indices with air and lake water temperature were analysed in the monthly cycle. Deviations of values of such components in different phases of the analysed atmospheric circulations types from mean average from the years 1971 to 2015 were also determined. The research showed a variable effect of the atmospheric circulations types. The strongest effect on water temperature was observed in winter, when AO and NAO circulation showed particularly evident influence. Deviations of water temperature from mean values from the analysed multi-annual period generally oscillated around 1.0 • C, reaching a maximum value of 1.4 • C. The presented research shows the complexity of processes determining changes in lake water temperature, the course of which depends on many factors with both regional (e.g., ice cover on lakes) and local range (conditions of water exchange, human pressure).

“…This is important in the context of the observed and confirmed with numerous climate warming studies [32][33][34]. The transformation of the current thermal conditions has and will have evident consequences, among others for lake ecosystems [35][36]. Undertaking measures potentially mitigating the effect of climate change on lake ecosystems requires the availability of possibly detailed data concerning their thermal regime.…”

One of the basic parameters of water ecosystems is temperature. Its value and distribution are of key importance for the course of biotic and abiotic processes occurring in rivers and lakes. The issue of correlations of thermal conditions with the above elements is discussed by various scientific disciplines [1][2][3][4]. Proper interpretation of the occurring correlations requires possibly detailed data concerning water temperature. Such information is collected in various ways, and covers, among other things, surface measurements [5] and measurements performed in deeper parts of waters [6].In the case of lakes in Poland, the history of measurements of water temperature dates back to the end of the 19th century [7]. Systematic observations of water temperature in lakes, however, commenced in the 1950s [8]. The measurements were coordinated by the State Hydrological-Meteorological Institute, which was later transformed into the Institute of Meteorology and Water Management (IMGW). Data concerning temperature refer to stationary (point) measurements of near-surface waters. The number of observation sites over the years has changed, partially due to frequent reorganisations Pol. J. Environ. Stud. Vol. 26, No. 5 (2017), 2159-2165 AbstractThis paper presents a comparative analysis of thermal images from Landsat satellites with in situ measurements of water temperature based on the example of three analysed lakes in Poland (Łebsko, Gardno, and Jamno). The coefficient of determination R 2 in the first two lakes reached a value of 0.95, and in the third case 0.87. The obtained results suggest high coherence of both of the sources. Satellite data obtained with such coherence with in situ measurements can be considered to be of high quality. The fact opens a new chapter concerning continuous monitoring of surface temperature of lakes in Poland, which can be considerably expanded in comparison to the current state (the measurement network is currently constituted by several tens of relatively large lakes). The issue addressed in the paper refers to a dynamic development trend in research based on teledetection information. So far, however, such methodology has not been used for detailed research on lakes in Poland. The availability of information on thermal conditions in reference to a possibly high number of lakes is of key importance in the context of the observed climate changes and the resulting transformation of water ecosystems. Continuous monitoring offers a basis for the development of applicative solutions, potentially reducing the effects of global warming.

“…rapid floods and occurrence of low flows. It should be emphasised, however, that lakes as concave landforms with positive matter balance (overgrowing, filling with sediments) successively lose their retention capacity [15][16][17][18]. Changes in water resources accumulated in lakes overlap with climatic fluctuations, manifested in water level fluctuations [19,20], or direct human interference [21,1].…”

Abstract. In the context of the observed climatic changes, unfavourable extreme situations occur increasingly frequently, manifested by, among others, the occurrence of droughts and floods. In the case of Poland, the central part of the country, in administrative terms covering the Wielkopolskie Province, is considered a region with a deficit of water resources. Such a situation was and is determined by a combination of natural and artificial factors. The former ones result from low precipitation and high air temperatures. The latter are the effect of intensive economic development, including large-scale meliorations. Measures mitigating this unfavourable phenomenon are related to the expansion of small retention. Its scale in Wielkopolska is the largest in the country -both in terms of the number of objects and volume of accumulated water. The key component of increasing retention is damming of lakes. According to the presented results, considerable reserves are still available in its scope. With the assumption of increasing water level in lakes by 0.2 m, it could cause an increase in water resources by 31 million m 3 , and assuming such an increase at a level of 0.5 m, by 78 million m 3 .
