March fishing means you will be enduring some weather conditions. You might have warm day today and very cold day tomorrow. You have to plan your trip based upon the weather including temperatures and wind. Something that helps in the spring is to fish deep, like 20 or even 25 feet in the big lakes. Deep crappie aren’t bothered as much by fronts and the barometer like they are when shallow. Trolling heavy jigs slowly along the bottom and to suspended fish can lead to success. –Brad Whitehead
