Zooplankton is an important component in water ecosystem that has a distribution in spatial and time scale. The distribution and diversity of zooplankton as one biological indicator of quality of the water way. This study was aimed at looking at the description of the distributional pattern and the abundance of zooplankton and Beratan Lake. Five sampling stations were determines based on the deeps of the lake using the field survey method, i.e., LB 1, LB 2, LB 3, LB 4 and LB 5. The zooplankton sample was taken from each stations by using Chaoborus net NXX 10 (the eye of the net size was 132 µ, then the zooplankton was preserved with 4% formalin solution. After being identified, there was five species, 4 Cladocera species and 8 rotifera species . The highest of abundance for copepod group was Thermocyclops. Diaphanosoma was Cladocera group which was mostly found. Conochilus unicornis was the most dominant rotifer .
