ICE COVER

Ponds and Lakes
Water freezes at 32-degrees F, but it is
most dense at 39.2-degrees F. During winter,
and before ice forms, the entire pond or lake
may be at this temperature. As the surface
waters cool more, the colder water layer stays
at the surface. If the surface water remains
calm and stays at 32-degrees F, ice begins to
form. The layer of ice is "floating" on top of
the lake-like an ice cube floating in a cold
drink. The ice forms from the surface down,
the colder the weather, the thicker the ice.
The water beneath the ice is insulated from
the cold and often remains at 39.2-degrees F.
Under the ice, the level of activity and
metabolism of fish is less than during other
times of the year. Using less energy means
fish can eat less. Fish may sometimes use
their stored energy reserves over the winter.
Other times, they may eat but do not use
much energy to find food. Bluegills eat
plankton and other invertebrates that remain
active during the winter. Small ice fishing
lures and flies imitate these food items. If
you know anything about ice fishing, you
know that fish don't move far or fast.
Fish may also move to deeper water
where temperatures are slightly warmer.

Young fish find refuge among vegetation or
other cover. Carp and bullhead catfish lie
still on the bottom or may bury themselves
in the mud. Sunken logs or human-made fish
structures offer protection for others.
Small increases in water temperature
may result in an increase of activity. A clear,
sunny day can warm the water just a few
degrees. The water entering a lake or pond
may also be warmer. Fish will move to the
warmer water. The fish and things they eat
will be gathered at these spots. Activity is
higher at these spots than other places due
to the warmer water and abundance of food.
Finding these places is the key to ice fishing
success. The opposite also is true, and a small
decrease in water temperature causes fish to
slow down. When this happens, anglers say
the fish are "turned off."
