editOn the upper course of the stream is built the fishpond Velký rybník. It has an area of 36 ha (89 acres). The pond and its surroundings is protected as the Velký rybník Nature Reserve on an area of 103.7 ha (256 acres). The area of wetlands, reedbeds, waterlogged meadows and wet forest is an important migration route for migratory birds. More than 170 bird species were documented there.[5][6]
