If you have not seen it, there is an interesting article in the March In-Fisherman magazine titled “When the Whites Run”. If you are looking for tactics and techniques for catching silvers the In-Fisherman article provides some good pointers.
I was just looking through my journal from last year and there was a good white bass run going on about 22 April. If you are looking for early season fishing action chasing white bass just after ice out may be the best bet.
