Floods in June 2013 affected mainly Bohemia and partly Moravia. The streams across the Vltava River basin, in part of the Elbe River basin and marginally in the Thaya River got swollen.
The effect of the flood on the Botič stream was further amplified by release of water from the Hostivař Reservoir. Hundred and forty years water caused considerable damage to property and it is likely that it also changed the character and size composition of biota, especially fish.
This change should be reflected naturally in the diet of kingfisher, which nests and hunts here.
