It would not with our slimmer healthier brothers but the shock of the cold can stop you breathing or even cause a heart attack with our plumper less healthy pilots.
But yes I too faced with landing in a forest would take a smooth lake or river anytime equally knowing that a short swim or maybe even standing up on the bottom and wading to the shore would see me safe.
A bit different to being 100-200 miles from land landing in a sea with 20 foot waves and freezing water
