Dead frogs are due to one or more of the following:

-Geezerhood
-Not enough food before winter
-Pond ices over without enough 02 available
-Pond ices over with too much rotting organic matter
in the water
-Frog settles in a pond that has taken a lethal dose
of pesticide or herbicide
- Frog settles down in an area that freezes solid,
only a few kinds of frogs have the natural 'antifreeze'
in their blood

Preventive
Keep a hole open in the ice, same as for fish. Larger
fish and frogs are the first to suffer poor water conditions.
Be vigilant about pesticide and herbicide in the water.
Monitor water conditions during the growing season.
Don't let chlorinated water or water with chloramines
in the water, use commercially available treatments.
