It looks like among both amateurs and researchers of the Eurasian lynx an opinion is wide-spread that the species strictly avoids cold water, in particular crossing cold waters of streams by swimming. Before camera-trapping by dealing with lynxes already quite a lot (study on population dynamics and diet in connection with changes in prey supply), we think like that, too.
Nowadays by using camera-traps and checking the question, we can say that lynxes are able to cross cold water by shorter or longer swimming. Also, it can walk up to 300 meters, at least, in cold water with legs and belly waterlogged. At the same time, we still fully agree that lynxes anyway prefer to be dry.
To argue that lynxes used crossing cold waters, we would like to demonstrate several examples.
Also, we registered regular swimming of two adult male lynxes across a medium sized river in the cold season, when the river is not ice-bound. It was swimming minimally for 30 meters. Both males were regularly photo-documented on both sides of the river, and there is no any bridge nearby. See the river below.
