The new pond in Nalžovské Hory is fed by the Nalžovský stream. Its area is over 31 hectares, and in terms of size, it is the fourteenth largest in the Pilsen region. Its length is almost one kilometer and at its widest point it is over five hundred meters. If we wanted to go around the pond, we would walk almost three kilometers. The dam is approximately three hundred meters long and about ten meters high. Several hundred-year-old oak trees grow on the embankment.
