Iowa wildlife officials are warning that this winter's extensive ice cover on lakes and ponds will worsen the fish kills that are a normal part of winter.
Fish die each winter when oxygen in the ice-covered water becomes depleted. This winter's ice started earlier and grew thicker than has been the case since at least 2008, according to the Iowa Department of Natural Resources.
