Mother nature sets the mood for the spring run.
Best conditions usually occur when water temperatures hit 45-50 degrees. This temperature turns on the biological clock be it the IL river,Missisippi, or where ever. I fish the Missisippi,IL river,Kish, and the Rock. First I work the upperlip of a deep pool, with a jig and minnow slipping with the current. If after 30 minutes with no fish I will work the deepest parts of the pool it self.
