I know it happens in some coastal areas such as the Baltic Sea or the Adriatic Sea, but I mean the biggest European freshwater lakes such as Ladoga in northwestern Russia or Vänern in Sweden.
Well, I know heavy snowfall by lake-snow events as they experience in North American Great Lakes don't occur, but I'm wondering about light snowfalls by lake-snow effect there.

What dou you think?

I don't know much about lake effect snow at all, but I guess that since Vänern is large enough to increase sunshine totals by 10%, I think it probably can manage at least some lake effect snow.

Didn't someone on here say the big Swedish lakes can produce lake effect snow?

Minor lake-effect snow, but not Michigan level of course.

However, in Örebro quantities of snow appear to be a bit more than 1 cm/mm quite often.

"Even our big lakes, Vänern and Vättern, generate their own small sized lake-effect snow, which is shown clearly on this radar picture that is from 10:00 today in the forenoon"

I do remember that snowfall. Örebro was covered from top to bottom in wet snow and it was slip-a-geddon outside

yes, they can.

In Sweden, the phenomenon is most common along the coastline between Söderhamn and Stockholm and between Västervik and Mönsterås. But the snow guns can also occur along other coastal stretches in the country where cold air flows out over open water, such as along the Gulf of Bothnia, Lake Vättern (Vättersnö) and especially Lake Vänern (Vänersnö).
A notorious snowmaking affected Gävle area in early December 1998, when it fell in one day 136 centimeters of snow, which paralyzed all transport links in the area.

a recent example of this was in december 2012, when kilagården 20km south of lake vänern got 75cm in a day (highest daily snow-depth increase ever recorded in västergötland), under a NNE-flow.

Never heard about this effect. I have googled a little bit. According to Wikipedia this effect even occurs in the Sauerland in North Rhine-Westphalia. The lakes there are very small.
