Right on. 55 - 58 usually has those males coming in getting ready to make the beds. spawning is usually at 62 - 68 degrees. Water from 6 inches as deep as 10 feet. Usually fairly hard bottom and in or near brush, hardstem, reeds, old weeds , etc, but not always. I have a few areas where they come in very shallow as soon as the water hits the mid 40s to feed on minnows. If the temps stay on a steady rise they will often stick around as these areas are also spawning bays. 50 - 55 degrees or so will often have the specks staged around the first deep water near spawning areas.
It is not about the equipment you have to use,
It is about how you use the equipment you have. :D
