Lake Jasna (Kranjska Gora)
Lake Jasna is a small (2.2 ha), very shallow lake in a former gravel pit at the confluence of the Velika and Mala Pišnica near Kranjska Gora. A long peninsula splits it into a northern half under 2 m deep, which warms to around 25 °C in summer, and a cooler, clearer southern half up to about 2.5 m fed by a stream. Schools of large fish wait near the footbridge at the tip of the peninsula and in the deepest south-eastern part. A loop of both halves takes about an hour; in summer bathers stir up the silt and spoil visibility.

- Unverified: Unverified: the only dive source is the Slovenian diving federation's atlas sheet (published GPS, but data from 2010s). Jasna lies at the entrance to Triglav National Park and we could not confirm whether the lake is inside the park boundary; inside the park diving is allowed only at designated places with the park's consent (ZTNP-1 Art. 13), and the park's 2012 letter names only Lake Bohinj and the Soča at Kršovec. Confirm with Triglav National Park / Kranjska Gora municipality before diving.
- Tips: Very easy, shallow dive, best outside the bathing season or in the cooler southern half; bring a compass. The lake freezes in winter. Check local rules before diving (see the unverified note).
