As much as many people are glad to see the warmer temperatures return this week, it could weaken ice on lakes and farm ponds that many ice fishermen like to use. Scott Voney with the State Conservation Department says watch out for ice that is cloudy, it might have frozen and thawed, weakening it. Good, clear ice at least four inches thick is needed to support a fisherman’s weight. And he says look for dark spots with “spider legs” radiating from the spot on lakes and ponds. Voney says if there is enough ice, this should be a good time of year to fish for bluegills.
