Pustý rybník (Desert Pond) – the mystery of an extinct pond
Pustý rybník is now a peat bog, but was it once a pond? This is what many researchers have tried to discover since the 18th century.
At the watershed of the Hradčanský potok (Hradčany Stream) and the Břehyňský potok (Břehyně Stream) is an area long called Desert Pond (Wüste Teich in German). It is a plateau covered by a peat bog with several springs of groundwater, which is divided into three parts: the Upper, Middle and Lower. The peat subsoil consists of fine-grained aeolian sands stored in the Quaternary. In the 18th century they were processed in the glassworks near Strážov. How was the peat bog formed? According to oral tradition, there was once a pond whose southern dam ran along today’s road to Strážov. In the north the pond was connected to today’s Držník Pond. If it is true, there would have had to be a 4-metre high dam at its north end. However, there is not a trace of the dam. Therefore, there has probably never been such a large pond.
