The Sutla (Croatian) or Sotla (Slovene) is a river flowing through Slovenia and Croatia, mostly forming their border. It is a tributary to the Sava, itself a tributary to the Danube. It is 89 kilometres (55 mi) long and has a watershed area of 584 square kilometres (225 sq mi).
|Sotla / Sutla|
|• elevation||580 m (1,900 ft) |
|135 m (443 ft) |
|Length||88.6 km (55.1 mi) |
|Basin size||584.3 km2 (225.6 sq mi) |
|Progression||Sava→ Danube→ Black Sea|
The Sutla flows through the following municipalities:
- in Slovenia: Rogatec, Rogaška Slatina, Podčetrtek, Bistrica ob Sotli, Brežice
- in Croatia: Đurmanec, Hum na Sutli, Desinić, Zagorska Sela, Klanjec, Kraljevec na Sutli, Brdovec
The division of the Sutla/Sotla basin area between Croatia and Slovenia is inconsistent in sources; Croatian sources claim either 343 km2 (132 sq mi) or 455 km2 (176 sq mi), while Slovenian sources claim either 477 km2 (184 sq mi) or 451 km2 (174 sq mi).
Kozje Park (Slovene: Kozjanski park), established in 1981 as Trebče Memorial Park (Spominski park Trebče), is located in Slovenian territory west of the Sotla. It covers 206 km2 (80 sq mi) of the landscape of the Kozje Hills (Kozjansko hribovje), including wetlands along the Sotla. It is the habitat of over 120 bird species and of about 950 higher plant species.
The earliest known mention of Sutla was in 1028, as Zontla. It has been suggested that the names Sutla and Sava are related, but this is uncertain. Another theory is that the name Sutla comes from the Indo-European root *su, meaning 'swine'.
