course

The Cedron rises north of the village of Stružinec in the Central Bohemian Hills ( Středočeská pahorkatina ). On its upper course leading to the southwest, past Nehonín and U Kaplice, the brook is dammed in the ponds Černý rybník, Nehonínský rybník, Velká Kaplice, Nový rybník and Obecní rybník. In Jistebnice the Cedron turns to the west, along its course are Zvěstonín, Pohoří, Zbelítov, Hodkov, Slabov, Petříkovice, Kotaškov and Hronova Vesec. From the mouth of the Nadějkovský potok the brook is called Smutná and flows past Vozdrakov, Hromadov, Modlíkov, Micáskův Mlýn, Vratišov, Prachárna, Cmuntov, Vlksice and Dolejší Mlýn to the southwest. The rest of the run goes through Duškanka, Božetice , Kvěchov, Vlkovina, V Chlumu, Chobot, U Vyhnalů, Závist, U Krajíců, Hanov, Srlín, Kozín, Rataje , Haškovcova Lhota , U Viktorů, Radětice , Na Prádle, Pichamelnoušť, Cihamelnouš, and to the south. On the western outskirts of Bechyně the Smutná forms a deeply cut valley with several river loops. After 47.8 kilometers the Smutná flows into the Lainsitz at the foot of the Bechyně Castle .

At Kvěchov the Smutná is bridged by the Tábor – Písek railway. East of Sepekov , the river is dammed below the remains of the Skalice castle in the Chobot pond.

Smutný natural monument

The section of the river below the Chobot dam has been protected as a Smutný natural monument since 1985 over a length of two and a half kilometers to the road bridge between Sepekov - Opařany. The 4.35 hectare reserve includes natural meanders through alluvial forest.
