[3] The cooling scheme varies with the time of year, with Licheńskie, Ślesińskie and Mikorzyńskie being included in June but excluded in October.

[5] In the mid 1990s, eel grass (Vallisneria spiralis), a non-native species, made its appearance in three of the lakes and a decade later was present in the littoral regions of four lakes, growing so vigorously as to exclude other vegetation in many shallow parts.

When the discharges from the power station into Lakes Licheńskie, Ślesińskie and Mikorzyńskie cease in the autumn, common roach numbers diminish from 28–56% of the total fish stock in June to 1–2% in October.

It is probable that the roaches migrate to the warmer lakes nearer the power stations in autumn.

[4] A number of animals more familiar from marine or brackish environments are also present in the Konin Lakes; these include the flatworms Bresslauilla relicta, Otomesostoma auditivum and Macrostomum rostratum.
