In order to encompass all corners of the lake for count, all the participants divided into two groups, and handed out the telescopes and binoculars. One group went around the south side of the lake, whereas the other group went around the north side of the lake. During the count, participants also had the opportunity to photograph these swans.

Out of all counted swans, 70% of the swans were encountered the north side of the lake and remaining 30% of the swans were counted on the south side of the lake.
