Water itself is not a great conductor of electricity. It's usually the minerals in the water that determine it's conductivity. Check the resistance between distilled water and salt water... there must be charged particles within the water (either ions or electrons) and these particles must be free to move. In water (H2O) the molecules are free to move, however, they carry little charge. Water itself contains 1*10-7 mol/Liter positivly charged H+ and the same amount of negativly charged HO- (ph 7)... that results in a conductivity of aproximately 0,055 µSiemens/cm (18,2 MOhm )for pure Water at 25 °C.

As water slowly freezes, it tries to exclude most ions from the growing solid, and they end up concentrated in the remaining liquid that usually evaporates. Since the ice is partly de-ionized, plus the molecules and ions cannot move most of the time, it would actually be less conductive.

Electricity can be passed through water only if it contains some dissolved impurities like salts which can give ions. In pure water, electricity cannot be passed. In case of ice, ions cannot move (impure ice) so electricity is not passed. Ice conducts electricity only about enough to dissipate static electricity.
If it's far colder than freezing, it might not even conduct that much.
