Abstract
This contribution presents a current occurrence of drought periods and declines of fishponds (including entire fishpond systems), in Poděbrady and Nymburk counties. Such relation is not straightforward, when we consider fishponds as reservoirs of water and energy.
Here we present, based on numerous historical examples, usefulness of a fishpond in periods of drought. We utilized recently levelled low water marks on, so called, Hungerstone in Děčín.
While our focus is on the decline of the "Blato" fishpond, established near 1790, formerly the largest fishpond in the area of today's Czech Republic, we also consider if the decline of fishponds is a consequence of drought periods.
