In the paper it is shown that the lakes of the North-Eastern Poland fulfil various functions in the groundwater phase of the water circulation. The value of the resultant of the groundwater supply to the lake, and in some cases also its direction, depend on the volume of the water undergoing a total exchange in the reservoir in the given year. In through-flow lakes the runoff increase coefficient also influences this value.

This article concerns the use of remote sensing methods to assess the potential of tourism and recreation of lakes by using unmanned aerial vehicles as a tool that offers new measurement possibilities in such difficult areas to research as river and lake systems. For the purpose of the study, air surveys over three lakes used for tourism and recreation purposes were planned and carried out. These were the following lakes: Swarzędzkie, Wolsztyńskie and Zbąszyńskie located in western Poland. The photos were taken with a RGB and a multispectral cameras. On the basis of calculated orthophotomaps and digital surface models, anthropogenic and natural values were assessed. The examples of the research show the versatile possibilities of using drones dependent on the type sensor used. Remote sensing performed from the deck of an unmanned aircraft is widely used in the study of lakes and is an alternative to existing land and water research methods.

The paper presents the dynamics of daily water temperature fluctuations in Lake Kierskie (West Poland) and determines the effect of air temperatures and wind speed on the variability of the parameter (water temperature). The analysis was based on hourly water temperature values from the period from May 2012 to January 2018. The data analysis permitted the description of the thermal regime of waters in the lake in the hourly cycle in reference to each month, and designation of months characterised by the highest and lowest stability of water temperatures. More than half of the analysed days was characterised by a change in water temperature not exceeding 1°C. The course of water temperature showed strongly positive correlations with air temperature, and weak correlations with wind speed. Water temperatures in the lake were correlated the strongest with air temperatures with a 24 h time step.

Geographical words referring to water, such as river, stream sea or lake, have been used in language since the earliest. As water is considered essential for life in general, the names of water reservoirs and watercourses became popular and frequently used items in all languages. The present study is focused on the English names of natural water reservoirs (sea, lake) and watercourses (river, stream) and their regional spread in the 12th–15th centuries. The Old English names of watercourses and natural water reservoirs, sӕ, flod and ea, either survived in Middle English in a modified form or were (rarely) replaced by loanwords as the effect of the Norman Conquest of England in the 11th century. The research is concentrated on texts selected from the Innsbruck Corpus of Middle English Prose (Marcus 2008), with some material coming from the OED and MED. The analysis will show the extent of the loss of the original Anglo-Saxon words or their spread, frequently with a modified meaning. The analysis will also include the statistics of the terms in question in prose texts representing the chief dialects of the period. As regards the method, the present author makes use of the traditional semantic theories (e.g. Lyons 1977) and the prototype theory (e.g. Geeraerts 1997).

The paper presents the names of 44 objects from the territory of Warmia and Mazury related etymologically to the German “Mühle” or Polish “młyn” and its derivatives as well as the Polish “wiatrak”. The analysis discussed names of 18 ponds, 9 lakes and 17 terrain objects.
