[4] According to the regionalisation drawn up by the Ministry of the Environment,[5] the Kashubian Lake District lies, as a whole, in the region of the Lower Vistula, and so its waters are subject to RZGW in Gdańsk.

[2] The mesoregion is able to be split in the following river basins: Radunia Reda, Łeba, Motława, Wierzyca, Słupia, and Łupawa.

In the division made by Augustowski, and by Kondracki, this region still includes the Wda and Brda river, which do not belong to mesoregion.

Unfortunately the costs limit the meteorological stations to local changes in temperature, pressure, the wind speed, and similar parameters.

The whole of the knowledge about the climate in the Kashubian Lake District comes from field research and meteorological stations found in health resorts.

Additionally, the Kashubian Lake District has a large variability in weather, which is quite characteristic feature to the region.

[9] The afforestation rate of the lake district of the Kashubian is quite significant in the comparison to neighbouring mesoregions; apart from the Tuchola Forest.

Among coniferous trees, the dominating is the Scots pine (Pinus silvestris) and the Norwegian spruce (Picea excelsa), in addition, the last of these kinds appearing in the region outside their natural range, mainly coming from fixing made by man.

[12] The oldest signs of mankind in the Kashubian Lake District originate from the older Stone Age.

[14] In the early Middle Ages, the lake district and neighbouring regions were ruled by the Duchy of Pomerania, which in 1294 as a result of the Union in Kępno joined to the Kingdom of Poland.

Later a period of battles had enrolled over Pomerania, causing losses in the economy in areas of the lake district.

The temporary detachment from Poland and from Germany caused the development of the region's own culture and the language, however Kashubians didn't create their own state.

Additionally, in a quite rapid pace a shipbuilding industry started growing, this caused many people to migrate from the region and into the Tricity.

When Poland had entered the European Union, this caused both financial benefits (EU funds for the development of the region) as well as an increase in the cultural diversity in the region, as many Kashubian institutions, and the Kashubian language was declared an official language – which was not possible during the times of the Polish People's Republic.
