The one thing I have heard a lot about is, snow storms entice the fish to bite. In some aspects this can be true. We all know that Barometric Pressure will have an effect on fish. This still stands true during ice season as well, so keep that in mind. During a snow storm there are obviously cloudy skies blocking the sun. On days that it is cloudy you can definitely find better fishing than on a clear blue sky day. The cloud cover will reduce light penetration, and very often when there is low light penetration the fishing becomes good. Many think that with the snow and ice this reduces the light causing the bite to be better all the time. This is false. If you have a foot of snow and ice on a blue bird sky day the fishing more than likely will not be all that great. Once you see some clouds rolling in on the horizon though, I would bet that the activity would increase dramatically. I came across an interesting writing by Bob Jensen on this matter that I would like to share.
Written by Bob Jensen:
I was on the ice recently with ice-fishing expert Tony Roach. We were on Mille Lacs Lake in central Minnesota and for days prior to my arrival, Tony and his guests had been pounding the walleyes, lots of'em, and big ones.
Our day on the ice coincided with a sizable drop in air temperatures and high blue skies. Tony knew right away that the bite might be off a bit, but you can't catch'em if you don't drop a line through the ice, so away we went.
Tony is a proponent of drilling lots of holes and covering lots of ice, kind of like trolling on the ice. We would fish a hole maybe five minutes, keeping a close eye on the sonar. If a fish didn't show up, we moved.
If a fish was seen on the sonar, but didn't eat our bait, we moved.
We moved a lot that day.
Tony had us on fish. I could see fish on my Humminbird 55 ICE unit come up and look at my bait, then slowly drift away. This sonar does an outstanding job of revealing fish just a few inches off the bottom. We tried smaller baits, bigger baits, different colors, different jigging actions: We tried everything we could to get bit, and every now and then we did get a walleye to eat our bait. But we saw a lot more fish than we caught.
We tried different areas, and saw fish in most areas. However, one area had quite a few more fish.
In the early afternoon, we noticed clouds building on the horizon. The wind picked up for a while, then calmed down. The weather was changing. Tony suggested we get back to the area that had the most fish. He wanted to be on the best spot when this weather system arrived.
A little later in the afternoon, when the cloud cover was heavier, the walleyes went on the bite. Action picked up noticeably. It was another lesson that weather does affect fish under the ice. If you're one of those folks who likes to fish through the ice, keep in mind that weather will affect the bite. If you're on the ice and notice a change in weather, keep your bait where the fish are. That's the only way to get bit
Good Luck this ice fishing season! Tight Lines and Happy Fishing!
