The paper presents results of bathymetric measurements performed on three crater lakes located in the “Meteoryt Morasko” reserve in west Poland. The maximum depth of the largest of the analysed lakes (1695 m2) was determined to amount to 2.6 m. The parameters of the lake (surface area, depth, etc.) are largely determined by a ditch dug through the crater in the north-western part of the lake, affecting the maximum water volume accumulated in the lake.
