Water spirits

When fishermen go to catch fish, they cut a hole in the ice on the lake, and they must pour a little bit of vodka from a bottle into the hole, then drink some themselves. This is said to please the water spirit, and it will send many fish to the hole.

If the fishing catch was good, one fish was thrown back as an offering to the Sea God.

If the Sea Elder was seen while out at sea, they tried to quickly sail to shore, as no good was to be expected then.

If the fishing catch at sea was good, some fish were thrown back into the sea, and the Lord's Prayer was recited. The fish were thrown back to entice the water spirit.

Before fishing, offerings were made to the sea god to ensure a good catch. Wool, fishing tackle, and other items were sacrificed to the Sea God.

In the lake lived the Lake God, who provided the fish catches.

Upon leaving the sauna, thanks were given:

Thank you, Water Father,
thank you, Water Mother,
thank you, Mother Mary!

There is some kind of whirlpool in the water (in a lake or elsewhere). If you happen to get there, the Nixie drags you in.

You must not look into the well, the fairy might pull you in.
