The sampling sites (station 1-20) were located along or across the three main channels of the Wichter Ee. The investigation was carried out in March and in September 1998 with a motorboat. Due to the water level being too low, stations 8, 19 and 20 could not be sampled in March and staton 3 not in September. A 0,1 m² van Veen grab was used for sampling. At each station, two macrofaunal grab samples were taken and sieved over 0,5 mm mesh size. Species number, numerical abundance and biomass were each calculated as means of the two samples at each station.
