The spectacular spring creeks of the Sava River – Sava Dolinka and Sava Bohinjka, Slovenia


 
 
 
 

Where the Sava Dolinka is born – Zelenci Spring
Zelenci is a spring and eponymous nature reserve near the town of Kranjska Gora, in the far northwestern corner of Slovenia. It is the source of the river Sava Dolinka, a tributary of the Danube. At Zelenci, water from the underground stream Nadiza re-emerges through the porous bottom of a two-meter deep lake, whose waters are noted for their deep, brilliant green. Zelenci is considered the beginning of the longer of the two sources of the Sava, the longest Slovenian river at 221 km. The spring is actually the re-emergence of an underground creek called Nadiza, whose first source is at Tamar, but which spends most of its course underground after disappearing at the Ledine gravel basin near Ratece.
The porous chalk of the Zelenci lakebed permits a constant upwelling of groundwater in the form of tiny jets, a phenomenon unique in Slovenia. The lake formed by the springs has a constant year-round temperature of 5–6 °C. From the lake, the water flows into a stream, which empties eastward into the "Blata" ("Muds"), a 200 m wide and one km long shallow marshland. The actual riverbed of the Sava Dolinka does not begin until after this, at Podkoren beside the slopes of Mount Vitranc.

Thousands of spawning fish in crystal clear water – Savica and Sava Bohinjka

The Sava Bohinjka is a headwater of the Sava River in northwestern Slovenia. At 41 kilometers in length, it is the shorter of the two headwaters that become the Sava River in Radovljica, the other being the 45-kilometer-long Sava Dolinka. The Sava Bohinjka originates under the Komarca Ridge at an elevation of 805 m, from springs fed by the Triglav Lakes Valley. Until it reaches Lake Bohinj, the river is known as the Savica ('little Sava'), and features the 60-meter-high Savica Falls (Slap Savica) at its source. It then flows through the Ukanc Gorge, before flowing into Lake Bohinj. It flows from Lake Bohinj as the Sava Bohinjka to Lake Bled, before meeting the Sava Dolinka near Radovljica.
The Sava Bohinjka is home of many species of fish, especially Brown trout, Grayling and Huchen, and the introduced Rainbow trout. But the most spectacular to observe are the Chub, when at the spawning season they enter the shallow water of the river to spawn on the gravel ground.
