Czech cavers put a lot of work and effort into research. They worked hard!
Discovery from below has become too difficult, so they are looking for a connection to the cave from above.
From the neighboring cave, the Polish cavers are following the draft in the direction of Boka, but they are not yet very close.
During severe droughts, they went from the Volčanski Ruti village to the spring and asked the water spirit for rain.
On the way home it started to rain,
(Pavel Medvešček - Klančar, 2015, Iz nevidne strani neba, page 115).
The temperature of the water in the spring fluctuates between 0.1o C
(January - February) and 4.0o C (at the end of September and on
the beginning of October), because of the inflow of deep karst waters.
It almost made "frost bite" of my mouth when it was cold, but it was very tasty warmed up.

The maximum flow of the Boka should be around 150 m3/s (together
with torrential water from gutters). Then the spray completely
covers the bridge and soaks the pedestrian to the skin.

Between rocks and stones, the Boka stagnates in large pools.
On the outflow gravels the water sinks into them. When it flows, the pools are small or non-existent.
Thursday, 26th July, 2018.
A rockfall with a volume of several thousand cubic meters occurred under it.
Rocks and stones covered the pools under the waterfall. Since then, they are gone, the water flows through the rockfall.
The floods will wash away part of the rockfall and significantly change the conditions in the Boka and the Soča riverbeds below its confluence.
