Lake Fish Kills

Some fish populations in the state could be hurt by this nasty winter. The State Department of Natural Resources says it's typical for lakes and ponds to have some fish deaths in the winter, but one official says this winter, they're seeing more lakes and ponds affected. Jim Wahl says a few lakes are experiencing lower-than-normal oxygen levels. A few lakes with a history of winter kills are now installed with aeration systems, which can help keep the lakes from freezing.
