I think this spring is going to be tough. In my opinion spring can be a very unpredictable time for crappie. One day they might be shallow only to have move out the next. Weather plays a huge roll if the weather is unstable as it always is in spring fishing will be hard. If the weather stays consistant it should be excellant this is a opinion based on my home waters.
Hopefully it wont warm to quick and be more of a gradual climb up in temps this year. It will stay cold and then warm up quick thats the pattern we been seeing the past few years.
