well as Biebrza, Łyna, Drw˛ eca [49].
The floodplain lakes in Poland are poorly recognized in terms of the geometry
of basins. Significantly more publications concern biodiversity concerning both the
composition and variability of species in the lake waters in the Słupia [54], Biebrza
[55], Vistula [56], Warta [57], and Łyna [58].
Bathymetric maps of selected floodplain lakes together with their location have
been presented in Figs. 6.9, 6.10, 6.11, 6.12 and 6.13.
6.6 Changes in Water Relations of Floodplain Lakes
The water relations of lakes located in river valleys are a result of the degree of
transformation of the natural environment of their catchment areas. In natural and
quasi-natural valleys, the water balance of the lake basins results from the way they
are supplied (confluent, contrafluent, profundal, etc.) and their functional period
(potamophase or limnophase). In general, it can be stated that the valleys of the
