These icy weather conditions almost cost this person his life!  Thank God he got out alive!  The next person(s) might not fare so well, should there be another accident.  The City/County probably ought to add reinforcements above the pond so  this doesn't continue to happen!  They should at least install a sign indicating this potential hazard lies ahead, WARNING drivers to take great caution in icy weather.  Since it's happened twice, it'll probably happen again.
