The Bohinjka is a short, 41 km alpine river that begins where the Jezernica outflow from Lake Bohinj meets the Mostnica, and runs to the Sava Dolinka confluence at Radovljica around 411 m. The lake acts as a giant sediment trap and hydrograph smoother — the Bohinjka inherits far steadier flows than a rain-fed Julian Alps river of comparable size, and its clarity recovers within hours of a spate. Above Bohinjska Bistrica the channel runs as partly-confined pool-riffle and glide on limestone and dolomite cobble. Downstream it tightens into the Soteska gorge between Jelovica and Pokljuka — a confined bedrock and boulder step-pool cut where the river penetrates a limestone ridge. The bed is stable and well-armoured; the main wading hazard is polished, algae-slick bedrock in the gorge section.
