Altitude: 240–250 m above sea level
Area: 100 ha (northern deposit), 124 ha (southern deposit)
Material: fly ash from the Opatovice power plant

 

In the 1970s-1990s, coal ash was transported in the form of water suspension to an ash pond east of Dříteč village (southern deposit), where a lagoon of 140 ha and up to 16 m deep was created. This area has been used as a golf course since 2007 after reclamation (drying, soil covering, grassing).

Fly ash and gypsum, a waste product of desulphurisation, is still deposited on the northern deposit, south of Bukovina. Part of the area was flooded until 1996. At present, the areas are gradually being reclaimed, partly they are being spontaneously overgrown with ruderal vegetation. The most significant population of the Natterjack Toad in East Bohemia is likely to disappear due to the reclamation.
